Area Forecast Discussion . Updated National Weather Service Billings MT 1023 AM MDT Wed Sep 23 2020
UPDATE. Minor tweaks made to line up RH values for tomorrow with neighboring offices. Rest of forecast in good shape. BT
Today through Thursday night .
Light rain showers continue to follow the front through far SE Montana early this morning, and should fully be out of the area over the next couple hours.
A weak overnight trough will help keep temperatures slightly cooler today and allow humidities to not drop below 20 percent at most areas. However, upper ridging returns in full force for the the latter half of today and into Thursday to bring temperatures spiking back to the upper 80s and allow for another very dry day. Following close behind it will be another, more potent cold front that looks to pass through in the late afternoon and evening. Prominent pre-frontal mixing looks to occur and allow west winds to gust up to 40 mph around the foothills and areas up to Billings, then the frontal passage will bring a secondary burst of winds to much of south-central Montana, also gusting up to 40 mph, making this a critical fire weather day. Hence have kept the Fire Weather Watch going. However, an atmospheric river allows some light rain to follow behind the front, mostly occurring overnight into Friday. Vertz
Friday through Tuesday .
Overall not much change to the going extended forecast. Pacific moisture still on track to fill in behind Thursday nights cold front, with scattered showers forecast for Friday into Saturday. Atmospheric River off the Pacific follows the northwesterly jet over the area Sunday and Monday with a continued chance of showers, though they may be more concentrated in narrow bands. Ridge builds strongly over the Pacific coast on Tuesday shifting moisture fetch east of the area ending precipitation chances.
Temperatures behind the cold front will be much cooler than those over the past week or two, but still only reaching normal for this time of year in the 65 to 75 degree range.
Precipitation amounts in the various blends have all dropped a good deal since yesterday for the Friday-Saturday time frame. That said the ensemble means for both the Euro and GFS continue to advertise 0.05-0.15 inches of precipitation possible during this time frame. Snow levels still drop to around 8000 feet Friday night which could bring some light accumulations to the Beartooth Highway into Saturday morning.
With the northwest flow and trof aloft through the extended good mixing should allow stronger winds to work to the surface, especially in the afternoon/evening hours. Increased winds closer to CONSMOS to account for this. Should see northwest gusts 20 to 35 mph just about each day from Friday through Monday. Chambers
VFR conditions will prevail over the next 24 hours. West winds near KLVM look to gust up to 25 kts during the afternoon. Gilstad/Vertz
