Area Forecast Discussion National Weather Service Spokane WA 255 AM PDT Sat Jun 22 2024

Warm and dry conditions will occur into Saturday with temperatures warming into the 80s and 90s. A dry cold front on Sunday will create elevated to critical fire weather concerns over portions of central and eastern Washington with widespread breezy to windy conditions. This will likely be followed by temperatures cooling back down towards normal values by Monday. Another warm up arrives on Tuesday and Wednesday before the next weather system arrives on Thursday.


Today through Sunday night: A layer of mid- to high-level clouds passing through this morning will give way to clear skies by the afternoon as a ridge of high pressure continues to strengthen over us. Temperatures will be 3 to 5 degrees warmer today than they were yesterday, ranging from the low 80s to upper 90s across the region.
These will be the warmest conditions we've seen yet this season, so remember to stay hydrated and take breaks in the shade or in air conditioning as needed if you're spending time outdoors!

Heading into tonight the ridge will shift eastward into Montana as a trough approaches the coastline of British Columbia just to our north. Winds will pick up as our region gets caught under the pressure gradient between the incoming trough and the departing ridge. Sustained westerly winds of 10 to 25 mph and gusts of 30 to 45 mph are expected.

In addition, early Sunday morning a dry cold front will sweep through the Inland Northwest, ushering in cooler, drier air.
Relative humidity values will drop to 12 to 25 percent behind the front with the driest areas being the Columbia Basin into the Palouse, the West Plains, and South Stevens, Pend Orielle, and Ferry Counties. With the combination of gusty winds through the day on Sunday and a dry airmass in place across Central and Eastern WA, the primary concern for Sunday will be elevated fire weather conditions.
Rapid fire spread may occur with any new and existing fires. A Fire Weather Watch has been issued from 1 PM to 8 PM PDT Sunday afternoon and evening.

The greatest area of uncertainty with this forecast is how low relative humidity values will drop in the Eastern Cascade Valleys Sunday afternoon. A marine layer west of the Cascades may seep over into the eastern valleys keeping relative humidity values above critical thresholds, but it's hard to say at this point. /Fewkes

Monday through Saturday: After the dry frontal passage on Sunday, Monday will see temperatures drop a bit further to near seasonal normal for late June (low to mid 70Fs). The pressure gradient will relax and breezy winds will taper off throughout the day. Given the cooler temperatures and lighter winds, the concern for Fire Weather should decrease as we move into early next week.

Under a zonal westerly flow through Wednesday, the Northwest will begin to load up the next upper level weather feature. Temperatures will gradually warm through mid week, however there are still disagreements in just what will take place Wednesday. The spread in forecast temperatures is quite large indicating uncertainty in the strength and timing of an approaching weather disturbance. Current forecast temperatures is near the 50th percentile which seems fitting with such a large spread of model solutions. An overwhelming 65% of the ensembles bring a weak trough along the WA/Canadian border while the remaining model guidance maintains a ridge of high pressure centered over the Northwest. By Thursday and Friday, there are much more certain and clear solutions indicating the frontal system will bring a return to cooler (near seasonal normal)
temperatures and chances for showers/storms across the northern counties of eastern Washington and north Idaho.

Thunderstorms: Wednesday, Thursday, and Friday the best chances for thunderstorms will be north of Omak to Deer Park to Spirit Lake. The far northern communities will see 10-15% chance for thunderstorm activity in the afternoon and early evening hours each day. For outdoor events late in the week and into next weekend, Spokane to Coeur d'Alene has the potential (10% chance) for isolated thunderstorms in the afternoon and evening hours Friday and Saturday. There lies uncertainty still. /Dewey

06z TAFS: The air mass under a shortwave ridge of high pressure will be dry and warm this weekend. For tonight through Saturday evening, surface winds will be light and clouds will generally be above 10 thousand feet.

FORECAST CONFIDENCE AND/OR ALTERNATE SCENARIOS: High confidence in VFR conditions through 00z Sunday. /GKoch -----------------------

Confidence descriptors: Low - Less than a 30 percent chance Moderate - 30 to 70 percent chance High - Greater than a 70 percent chance
