Area Forecast Discussion National Weather Service Spokane WA 230 AM PDT Tue May 11 2021

SYNOPSIS. A gradual warming trend is expected this week with high temperatures climbing well into the 70s and low 80s by Thursday. Above average temperatures have the potential to linger into the weekend. The majority of the Inland Northwest won't get any rain this week, but a few weak disturbances will produce some hit and miss showers mainly over the mountains Tuesday and Wednesday as well as Friday into the weekend.

DISCUSSION.

Today through Wednesday night: A weak shortwave trough of lower pressure is sagging in over the northeast portion of the region early this morning out of BC. Weak echoes have been developing on radar over the Northeast Mountains to the Northern Panhandle with this feature as it interacts with a little bit of mid level instability. It's unlikely that much if any of this precipitation is actually measuring at the surface with dew depressions of 10-15 degrees at the surface. Much like the past few days, we will see the cumulus development over the higher terrain of northeast Washington and in the central to northern Idaho Panhandle with afternoon heating. Temperatures up at 500 mbs will only drop down to around -22 to -24 Celsius, which doesn't appear to be cold enough to achieve the charge separation for lightning. I can't completely rule out a stray lightning strike, but appears the the better chances for thunderstorms will be into Montana.

Then we will get a weak frontal band that moves across Wednesday into Wednesday night. There will be little reflection of this front down at the surface. Models aren't depicting any cold air advection translating down to the surface. The fingerprint of this front will remain at upper to mid levels for the most part. It will strengthen the cross Cascade gradient with winds becoming breezy through the Cascade gaps late in the afternoon on Wednesday and into Wednesday evening; however, much of the rest of the region will just see a lot of mid to high level cloud cover. Precipitation with this front will be limited to the northern mountains with up to 0.05 of inch or less expected at any one location.

We will see partly sunny skies today and then mostly cloudy on Wednesday. Most areas will continue to warm up a bit on Wednesday despite the cloud cover. The Methow Valley, Omak, and Republic will be a couple of degrees cooler on Wednesday, but across the basin and into the Idaho Panhandle temperatures will warm 3 to 5 degrees with highs in the 70s to low 80s.

Thursday through Monday: Flat ridging continues through Thursday. Spread in the ensemble members after Thursday reflect uncertainty in timing, positioning, and intensity of whatever trof type features pass thru after. Whichever the case the expected lowering of 500mb heights resulting from features moving through merits a gradual cooling trend through this interval after the daytime highs peak Thursday/Friday. A spotty reintroduction of pops for showers involving possible trof passage Saturday followed by brief shortwave ridging Sunday then another possible trof passage Monday. Pops are highest for the Saturday trof passage and even then a good portion of the East Slopes of the North Cascades and lowland and basin locations are likely to remain dry. Breezy Southwest/west winds are a possibility with the Saturday trof passage. /Pelatti

AVIATION. 06Z TAFS: Light winds and VFR conditions are expected through the night and into Tuesday. A shortwave disturbance dropping down out of British Columbia will produce showers over the mountains of northeast Washington and into the northern Idaho Panhandle through Tuesday afternoon including airports in Colville, Bonners Ferry, and Sandpoint. /SVH
