Area Forecast Discussion National Weather Service Medford OR 335 PM PST Wed Mar 3 2021

SHORT TERM. (Tonight through Friday night) . Our current episode of late spring weather occurring here in late winter is nearing an end. There will be a change in our weather pattern on Thursday as a broad trough over the northern Pacific moves southeast. There will be a gradual cooling trend, including lowering snow levels with mainly mountain snow on Friday night. But, more notably, moderate to heavy rain at the coast and in western Siskiyou County Thursday night through Friday, and strong, gusty southerly winds across much of the area Thursday through Friday.

There are model differences in timing of a slow moving cold front, but growing agreement in its strength. Thus, High Wind Watches for the coast, Shasta Valley, and Lake County from Thursday into Friday have been upgraded to Warnings, and a Wind Advisory issued for the Rogue Valley. Winds look to remain gusty during Thursday night, but likely strongest during the day-time hours of both Thursday and Friday.

The NAM remains about 6 hours slower than the ECMWF, while the 12Z GFS was in-between but the 18Z run has sped up to closely match the ECMWF timing.

One of the other forecast adjustments was to hold off on any mentionable probability of rain in the Rogue and Shasta Valleys until Friday afternoon, and reduce expected amounts (as well as in the Umpqua Valley) with the effect of the downslope southerly winds.

Rain is likely at the immediate coast by the end of Thursday afternoon with progression only to the Coast Range by sunrise Friday morning, and the Cascades by Friday evening, continuing across the east side Friday night into Saturday morning. Storm total precipitation of about 2 to 3 inches is expected at the coast, a quarter of an inch to an inch for most inland west side locations, and a tenth to a half inch for the east side. The impact of snow is a signficant forecast challenge with the warmth of ground temperatures, and (to an extent) late season longer days/shorter nights as important factors. As mentioned above, Friday night will be the main period of interest for snowfall impacts with snow levels forecast to drop from around 5500 feet to a range of 3000 to 4000 feet. For an event total, 3 to 6 inches of snow are expected for the Cascades and generally an inch on the east side. Higher amounts (around 6 to 12 inches) are expected for the high peaks of Siskiyou County, generally above 5000 feet.

LONG TERM. (Saturday through Wednesday) . Not much has changed in the overall scheme of things. Confidence is high the active pattern will continue during the forecast period. However it may not be all that bad overall this coming weekend. It won't be completely dry, but there could be larger periods of dry time. By next week, storms originating from the Gulf of Alaska will drop down into the Pacific northwest. Typically these result in cooler and unsettled weather.

Saturday, the upper trough shifts east of the area during the morning and we could actually catch a relative break in the action from Saturday afternoon through Saturday evening as weak ridging builds into the area. This break could carry over to Saturday night before the next front arrives Sunday. However the operational ECMWF and GFS suggest the front on Sunday will weaken as it moves inland, thus limiting the amount of precipitation, especially inland away from the coast and coastal mountains. This is also being supported by the ensembles and individual ensemble members.

The pattern will become more active Monday through Wednesday as an upper trough from the Gulf of Alaska drops over the forecast area with multiple systems moving through. The exact timing this far out will likely change over time. However we are confident they will be continued cool and wet. Not only the operational ECMWF and GFS show this, but so do the individual ensemble members of the ECMWF and GEFS. Precipitation amounts during this time are not expected to be significant at any one time during this period which will help to limit road snow concerns, especially during the daylight hours. Some snow will accumulate at night for the higher passes and possibly the lower passes on I-5 between Grants Pass and Canyonville. However, since its early to mid March, the longer daylight hours and higher sun angle should result in little or no road snow for the lower passes at least during the daytime. -Petrucelli

AVIATION. For the 04/00Z TAF Cycle . Along the coast and just offshore, VFR is occurring along the coast, with MVFR CIGS occurring offshore. The MVFR CIGS are expected to return to the coast tonight before lifting back to MVFR Thursday morning. Gusty winds from the south or southwest will begin tomorrow morning lasting through the day.

Inland westside . expect VFR to continue through the TAF period with the exception of some MVFR/IFR CIGS banking around the terrain in the Umpqua Basin and possibly at KRBG. Gusty winds will also be occurring in most north-south oriented valleys, especially funneling into the Rogue and Shasta Valleys. Despite the increase in winds in the Umpqua Valley, wind shear may be possible in the Illinois Valley and at KRBG, although confidence was too low to add them to the TAFs.

Elsewhere, VFR conditions will prevail through the TAF period. South winds will increase at Klamath Falls towards the end of the TAF period. -Schaaf

MARINE. Updated 200 PM PST Wednesday 03 Mar 2021 . Buoy data outages continue, preventing comparisons of the forecast to current conditions, so the forecast this afternoon is based almost entirely on model data.

Light northerly winds will shift to the south this evening as high pressure weakens and a strong, slow moving frontal system approaches from the eastern Pacific. The storm will move into the region tonight into Thursday, with strong Gales and periods of Storm force winds expected Thursday and Friday, along with very steep wind driven seas in excess of 20 feet. While Storm conditions should remain beyond 10 nm from shore, Storm force gusts are possible elsewhere, especially in the vicinity of headlands and capes.

Combined seas are now expected to peak in the 20 to 27 foot range Thursday night into Friday morning as those very steep southerly wind seas combine with moderate northwest swell at 17 seconds. The highest combined sea heights are most likely to occur about 20NM west of Bandon and the lowest along and near protected portions of the coast.

Wave models continue to decrease the threat of long-period large swells early next week, but steep seas appear likely, with seas in excess of 10 feet expected for much of the week as additional systems pass through the region. -BPN
