WEDNESDAY, May 22 Discussion
GOOD to EXCELLENT smoke dispersion conditions are expected Wednesday as the broad upper level low pressure area wobbles over Central OR/WA and drapes a warm front across Central ID and MT. Latest model runs have backed away from a widepsread soaking. Now it appears that the areas most impacted by precip will be NW MT and the N ID panhandle...ahead of the Warm front. Transport wind flow will be from the S in most locations, with temperatures above normal from SW MT eastward and below normal west of Missoula (due to cloud cover).
Extended Outlook:
Right now it appears that the low will now linger over the Pacific NW/SW Canada for several more days and will give all areas West of Central MT another round of precip Thursday night-Mid day Friday. Some clearing could briefly occur Friday afternoon. Saturday and Sunday appear to be warm, dry days for most locations...though some scattered wet storms will be possible in the afternoon. Transport wind flow will continue to be from the SW during this period and smoke dispersion will remain GOOD to EXCELLENT. Looking out in to the latter extended...there are no significant issues that would hamper smoke dispersion. The periodically moist SW flow pattern will continue as another Low pressure area drops sout from the Gulf of Alaska. The overall pattern suggest a continuance of warm, unstable, and somewhat moist conditions that will lead to the development of scattered afternoon thunderstorms each day.

THURSDAY, May 23 Discussion GOOD to EXCELLENT smoke dispersion conditions are expected Thursday as the broad upper level low pressure area continues to wobble over OR/WA and keeps the atmosphere well mixed over ID and MT. Showers again will be on the increase in the afternoon and especially the evening as another batch of significant moisture moves up in the moist southerly transport wind flow which will be light across ID but transition to breezy as you cross the Divide into E MT. Extended Outlook: Right now it appears that the low will now linger over the Pacific NW/SW Canada for several more days and will give all areas West of Central MT another round of precip Thursday night-Mid day Friday. Some clearing could briefly occur Friday afternoon. Saturday and Sunday appear to be warm, dry days for most locations...though some scattered wet storms will be possible in the afternoon.
