Marine Weather and Tides
12/16/2019 NOAA is having trouble with requests that include wind gusts. I am posting graphs without wind gusts until it gets fixed.
10/9/2019 Updated the Marine Zones.
9/4/2019 Fixed the weather maps due to NOAA moving them.
7/25/2019 New feature in the Airports section gives a link to 5 minute updates for data reports.

AVIATION. 18Z TAF CYCLE NWerly surface winds will help usher in drier air this afternoon, essentially shutting off the moisture tap we've seen the past several days. Thunderstorm development today will remain east of terminals this afternoon. Therefore expect VFR conditions with ceilings FEW120 FEW250 and northwest winds AOB 10 knots.
PREV DISCUSSION. 154 AM MDT Mon Aug 10 2020 .
SYNOPSIS. A westward shift in the upper-level ridge will interrupt the 2020 monsoon across the Borderland as it brings in a much drier airmass for the work week. Monsoon moisture will get pushed south of the region as drier air moves in from the west and north. This will mean few to no storms across the region for most days this week. The presence of the upper high will also mean we are in for a period of well above normal heat as we see a streak of 100 degree afternoons across the lowlands that should last into next weekend. Lowland highs will average in the 102 to 105 range, as overnight lows stay warm and mild. Heat, not storms, will be the significant weather concern for the week. Moisture and storms should be on the increase next weekend.
DISCUSSION. SHORT TERM. Today and Tonight . A broad area of high pressure continues to gradually shift back to the west and strengthen overhead. Due to the changing position of the ridge, our winds look to become northwesterly today. This means that our moisture tap will be cut off and drier air will push in. Dewpoints are forecast to drop into the upper 30s to mid 40s this afternoon and PW values will decrease to less than three-quarters of an inch. Also, CAPE basically looks to be nonexistent, with the exception being over the mountains. With all of that being said, precip chances are expected to become very limited starting today. A few hi-res models show short-lived scattered cells developing this afternoon across portions of the lowlands. However, I think we'll struggle to get any storms to form outside of the higher terrain. Slightly higher dewpoints and minimal CAPE values will be present in the Sacramento Mountains, so the best storm chances are forecast to be there. Kept low PoPs in for Otero and Hudspeth Counties in case something drifts down from the mountains behind an outflow. High temperatures will warm another degree or two this afternoon resulting in most of the lowlands topping out at or above the 100 degree mark.
LONG TERM. It appears we got an early start to the drying and stabilization of the airmass over the Borderland on Sunday, as we saw a dramatic drop in the coverage of showers and storms across the region. This trend will continue and persist through most of the week ahead as upper-level high pressure stays parked directly over our forecast area. The monsoon moisture plume will cut off with the bulk of the moisture staying south of our region due to the circulation around the high importing a drier, more continental airmass in from the atypically dry SW and Great Basin regions. The GFS and the NAM models differ significantly on the magnitude of the drying; the GFS with PWATs around 0.75" and the NAM around 0.90". None the less, with warm air and subsidence aloft, PWATs below 1.00", and surface dewpoint mixing down into the 30s and lower 40s each afternoon this week, the airmass be likely be too stable and too capped to generate more than a couple of (mainly) mountain storms each afternoon.
The big weather message for the week will be HEAT. Temperatures will be well above normal with highs generally 10+ degrees above mid-August normals. This means most of the lowlands will see 100 degree afternoons each day this week. Overnight lows will also tend to be mild, with urban areas keeping the heat, and staying in the mid to upper 70s. Therefore, it is quite possible that Heat Advisory criteria will be met for the TX Rio Grande Valley, and El Paso.
Late in the week (FRI/SAT) models suggest a further westward jog of the the upper high, as weak shortwave troughs track east across the mid and upper Plains. This should allow for a reintroduction of moderate low-level moisture back into our region on east winds behind door boundaries that will push into our region from the east. We will begin to include POPS, although low, back into the forecast by Friday/Saturday. However the coverage does look to stay mostly isolated in nature, and temperatures appear to stay quite warm.
FIRE WEATHER. An area of high pressure will shift back west over the Borderland starting today and persist through at least mid to late week. This will usher in drier air and limit any afternoon storm chances to the higher terrain. Min RHs will drop to 10-15% through Thursday and high temperatures will top out above 100 degrees in most lowland locations each afternoon. Winds look to remain fairly light, except for around any thunderstorms that develop where gusty, erratic winds will be possible. Vent rates will generally be fair to good.
