SHORT TERM
Tonight and Sunday Our prolonged period of above normal and dry weather will come to an end over the next 24 hours. The ridge of high pressure that had been in place for days is getting pushed to our south as an upper level trough digs into the PacNW. As such, afternoon satellite imagery shows gradually increasing cloud cover over the region. We do have some occasionally breaks where the sun is able to peek through but clouds will continue to increase as the evening progresses. Still seeing some lingering fog in the Bear Lake Valley but surface obs and satellite show this not being as widespread as it was so allowed the Dense Fog Advisory to expire earlier this morning. The aforementioned trough will push a cold front through the region late tonight and into the overnight hours which will bring a brief period of snow to just about everyone across eastern Idaho. Throughout the day, hi-res CAMs have shown the line of precip along the front a bit more organized in nature compared to 12-24 hours ago. That being said, there still isn't that much moisture associated with it so most valley locations are only expected to see a quick dusting, perhaps an inch at best if a few spots overachieve. We'll probably only see snow in the valleys for a brief period of 2-4 hours. Any accumulations of note will mainly be limited to the higher terrain of the central mountains and eastern highlands and even this is 1-3 for areas located between 6kft-7kft in elevation. Above that, totals could be a touch higher but impacts, obviously, won't be felt by too many. Given the forecast snow amounts remain light, no need for any winter weather highlights. Winds will increase as well later tonight and remain breezy into the day Sunday. Expecting locations in the Snake Plain and Magic Valley to see 15-25 mph winds with gusts 30 to 40 from late tonight and into Sunday evening. The front will usher in colder air behind it so temperatures will return closer to normal tomorrow with highs mainly in the 30s and area lows ranging from the single digits (mountains) to teens and low 20s elsewhere. McKaughan
LONG TERM
Monday through Saturday Northerly flow with a couple of weaker storms clipping the Divide will keep showers going into Tuesday. Amounts will be very light and may end up being nothing more than occasional flurries. There will be a decent range in temperatures across central and eastern Idaho. Closer to the Divide, highs will remain in the 20s, while closer to 40 across the Magic Valley and lower elevations of the South Hills. By the end of the week, look for more rain and snow across the area. It is a matter of timing with the next storm moving into the western US. About 60-70% of the clusters agree with a faster system similar to the ECMWF for Thursday and Friday.
Our Blend of Models has precipitation both days which seems plausible with the differences in the models and ensembles.
Another storm will be right on its heels for the weekend. Overall, a much more active pattern than what we've seen in the past week or two. Keyes
AVIATION
VFR conditions in place this afternoon with light winds and gradually increasing cloud cover ahead of an approaching cold front. CIGs will gradually lower throughout the evening and especially during the overnight hours. As the front moves through, a brief period (2-4 hours) of snowfall is likely to impact all terminals across eastern Idaho. Since the 18Z TAF forecast, hi-res models are showing a more organized line of snowfall associated with the front compared to earlier. As such, subsequent forecasts will likely need to swap out VCSH for -SN and a brief period of MVFR or even IFR VSBYs to account for the brief period of light snow. At KDIJ, snow could linger post FROPA through much of the day Sunday while KSUN should be clearing out (clouds and precip)
by midday. Valley terminals should be done with snow after the main FROPA so not expecting much precip after 12Z or so. Winds will begin to increase during the overnight hours and continue for much of the day Sunday in the 15-20kt range with higher gusts namely at KPIH, KIDA and KBYI. McKaughan
