.Updated Aviation Discussion.

DISCUSSION
After a fairly active afternoon in northern Klamath, Lake, and eastern Douglas county. things are starting to settle down. Only a handful of lightning strikes are being observed in central and northern Klamath County and storms should diminish in the next couple of hours. There was one severe thunderstorm Warning that was issued earlier this afternoon that covered an area between Chiloquin and Chemult on highway 97 and just east of highway 97.
There were reports of dime size hail in Klamath Falls and A Pilot gas station in Chemult. However the report in Chemult was west of where the heavier cell was located. There was a post on X formally known as twitter with a picture of hail close to the size of a golf ball in Chiloquin.

The upper low is slowly moving into the Bay Area and the orientation of precipitation is starting to pivot from southeast to northwest towards east to southeast to west to northwest. The latest high res guidance continues to show more stratiform like precipitation setting up over northern California and southern Oregon later this evening through the overnight hours. Precipitation amounts will be highest in northern California, and less farther north in southern Oregon.

A few updates were made for this evening to reflect the latest radar and high res guidance which shows limited activity until late this evening, followed by increasing steadier precipitation overnight tonight. Precipitation will continue Sunday, but will gradually diminish from northwest to southeast as the upper low slowly moves east. Please see the previous discussion for more details from Sunday through next week. -Petrucelli



AVIATION
14/06Z TAFs...A mix of MVFR/VFR conditions persist across most of the region this evening along with widespread terrain obscurations. A broad area of rain is pushing east to west across areas mainly east of the I-5 corridor and isolated thunderstorms continue east of the Cascades. Low pressure responsible for this weather will continue tracking inland into California and this will maintain shower/thunderstorm activity overnight into Sunday, though the focus will shift south and southwestward as the upper level flow changes.

Along the coast, a mix of IFR/LIFR conditions persist, though ceilings are expected to lift to IFR overnight tonight. /BR-y



MARINE
Updated 740 PM Saturday, April 13, 2024...Low pressure will continue affecting the region through Sunday, bringing gusty northwest winds to the waters through the remainder of the weekend.
These gusty winds combined with a westerly swell will maintain steep seas with conditions hazardous to small craft for all areas beyond 5 nm from shore through the weekend.

Conditions improve by Monday morning as the upper low moves further south and atmospheric stability builds. Improved conditions will be short lived, however, as a thermal trough develops on Monday afternoon and could remain in place through midweek or longer. This pattern would bring another round of gusty north winds, along with steep to very steep seas, especially south of Cape Blanco by Monday afternoon. /BR-y

Updated AVIATION discussion

SHORT TERM...Well-defined low pressure spinning offshore of the north-central California coast early this afternoon. This system will cause active weather across our forecast area this afternoon through Sunday evening with numerous showers and also the potential for thunderstorms. Current radar is fairly benign at the moment with a corridor of showers extending from the Mt. Shasta region NW through Jackson and into Douglas/Coos counties. Several lightning flashes have recently accompanied a cell in NE Jackson County near Butte Falls and is crossing into SE Douglas County.
Model guidance continues to show broad southeasterly mid-level flow, which will continue to advect moisture into the area through this evening. Outside of the showers, high clouds are prevalent across the area, including over the East Side. This may be delaying convection somewhat, but surface heating will continue this afternoon and this will allow the atmosphere to become more unstable. Steep mid-level lapse rates, modest CAPE and ample shear supported by the left exit region of a 60-80kt upper level jet will allow convection to develop in the next couple of hours.
The convection will move NW at a pretty good clip with storm motions of 25-35 mph. Convection allowing models (CAMs) are showing at least a slight chance (>15%) of thunder across a large portion of the CWA (all but the immediate coast and SW Siskiyou County). But, the highest thunder probabilities (>50%) extend from northern Modoc into western Lake/Klamath and over to eastern Douglas County. The Storm Prediction Center has highlighted these areas as a marginal risk for severe thunderstorms. The stronger cells in those locations will have the ability to produce strong, potentially damaging wind gusts, hail and brief heavy rainfall.
Given the strong shear expected and recent model soundings also showing a decent rotational component, if a supercell were able to get going, even a tornado cannot be ruled out (2-5% chance). Time frame of greatest risk: 22-02z (3-7pm). While any thunderstorm could produce gusty winds and small hail, the most likely areas for severe thunderstorms will be across northwest Lake/northern Klamath and into eastern Douglas counties.

This convection should morph into an area of showers and embedded thunder this evening, eventually pivoting southward across SW Oregon and becoming a steadier rain area in NorCal overnight. This area of steadier precip will change to snow in some areas tonight into Sunday morning as snow levels drop from 5500 feet this evening to around 4000 feet tonight. How low the snow levels get will depend somewhat on precipitation intensity. If precip rates are consistent enough, a changeover to snow may also occur around Mt Shasta City (after midnight) and wet snow could mix in down to as low as 3000 feet by Sunday morning. The overall forecast in those areas remains unchanged, however, with a winter weather advisory in effect for at least some minor winter impacts, especially over higher passes by Sunday morning. Snow amounts by Sunday morning (11 am) look to be in the 2-6 inch range, with some of the higher passes, like Cedar Pass on Highway 299 east of Alturas possibly receiving a little more than 6 inches. Other passes that are expected to be impacted by snow Sunday morning -- Highway 97 near Grass Lake, Highway 89 near Snowman Summit/Pondosa and Highway 139 south of Tionesta to Adin. The higher pass on Sawyers Bar road west of Etna and Highway 3 south of Callahan could also see some impacts. I-5 should be OK, though wet snow could bring a bit of accumulation on non-paved surfaces.

Most areas will be damp/wet Sunday morning, but the upper low should finally get a kick eastward Sunday afternoon. Precip probabilities (highest in the morning 50-80%) west of the Cascades decrease to 15-40% in the afternoon (highest south end of Rogue Valley and in the foothills). It'll remain wet/showery all day into Sunday evening in NE California and over the East Side and and there's still a chance of thunderstorms. Upper ridging will dry things out Sunday night.

LONG TERM
PREVIOUS
Sunday through Friday, April 14-19, 2024...(Issued 435 PM PDT Fri Apr 12 2024)

Sunday afternoon, shower chances remain highest from the Cascades eastward with PoPs generally in the 40-70% range, except up above 80% in Modoc and eastern Lake counties due to their closer proximity to the low. Snow levels in NorCal should rise some again Sunday afternoon to above 5000 feet. In addition, there is still a slight chance (20%) of thunderstorms over the far East Side. PoPs diminish (to 10-30%) Sunday afternoon west of the Cascades as heights begin to rise; some sunny breaks are probable as well. Isolated showers probably linger into Sunday evening over the far East Side. High temperatures Sunday will be at least a few degrees below normal in most cases, but as much as 10-15F below normal in NorCal.

We expect things to calm down Sunday night through Monday night as the low finally exits to the east and an upper ridge noses in. A few sprinkles/flurries are possible (20% chance) in far northern sections of Douglas County, but most likely it will be dry. The rest of the region will be dry with moderating temperatures, but still remaining at least a few degrees below normal Monday afternoon.
While it looks to remain above freezing west of the Cascades, much will depend on cloud cover Monday night; low temperatures could be in the mid 30s in the valleys west of the Cascades.

Tuesday onward appears to be a largely dry period, but with upper level pattern variations that make the temperature forecast a little less certain. Initially, an upper trough swinging through to the north on Tuesday may make for some breezy conditions during the afternoon, but precipitation chances remain low and mostly to our north. It could get chilly Tuesday night with patchy/areas of frost by Wednesday morning in some valleys west of the Cascades. The overall trend after that is toward milder temperatures, with the latest model clustering showing some semblance of upper ridging, a thermal trough and a period of offshore flow. NBM indicates high temperatures getting back to above normal levels as early as Wednesday, but then especially Thursday/Friday with highs in the mid to upper 70s west of the Cascades. -Spilde

AVIATION
14/00Z TAFs
Active weather continues this afternoon, especially for areas east of the Cascades. Thunderstorms continue to move to the northwest across northern Lake and Klamath counties while smaller cells are popping up over Modoc and eastern Siskiyou counties. Other less intense showers are expected to continue over Jackson and Douglas counties this evening. While showery activity will likely continue through the night, thunderstorm chances will decrease quickly overnight.

Precipitation chances overnight and tomorrow are the highest (80- 100%) over Siskiyou and Modoc counties. Snow levels are expected to lower to 3500-4500 feet, which may bring snow showers over higher terrain. Rain or snow showers may locally lower ceilings and visibilities as well as obscure terrain. Scattered precipitation is expected to continue through the TAF period but start to decrease in areal coverage by Sunday afternoon. -TAD

MARINE
Updated 820 AM Saturday, April 13, 2024
A low pressure system is currently situated near the Bay Area. Light showers are expected over the Pacific through the weekend, but the threat for thunderstorms has shifted onshore, and is less than 10% over the Pacific.

North winds will become more northwesterly throughout today and will increase in speed. The combination of gusty winds and westerly swell will result in steep seas with conditions hazardous to small craft for all areas beyond 10 nm from shore through the weekend.

Conditions improve by Monday morning as the upper low moves further south and atmospheric stability builds. Improved conditions will be short lived, however, as a thermal trough develops on Monday afternoon and could remain in place through midweek or longer. This pattern would bring another round of gusty north winds, along with steep to very steep seas, especially south of Cape Blanco by Monday afternoon. -Miles/Smith
