Discussion...look for scattered to numerous showers and
thunderstorms today as an upper level low with associated sub-
tropical moisture moves into southeast Idaho. Models continue to
indicate a 10 to 15 degree drop in temperatures from Sunday across
the area today. Models are showing the majority of the
precipitation moving in from our south northward along the eastern
Highlands where .25 to .5 inch of rain is expected. Look for a
decrease in precipitation Tuesday where just isolated showers and
thunderstorms are expected. A stronger disturbance moves through
the area on Wednesday bringing a better chance of showers and
thunderstorms. Expect a drier trend Thursday into early Friday.
Models continue to show another system approaching from the
southwest Friday into Saturday bringing back good precipitation
chances. Weak high pressure ridging builds in late Sunday bringing
a drier trend Sunday afternoon through Monday afternoon. Wyatt

morning...triggering a rain showers/thunderstorms and rain risk at all airdromes. This should
continue through the evening hours...then clear from west to east.
Northerly or light and variable wind this morning will shift to a
westerly component for the afternoon and early evening. Outside of
thunderstorms and rain significant impacts to ceilings or visibilities expected.


Fire air mass change will end the hot and dry
temperatures with thunderstorms and higher humidity/lower
temperatures. Red flag will continue for the selected elevations in
the Idaho-Utah border region where fuels have reached critical
dryness. More showers and thunderstorms are expected at least each
afternoon and evening from Tuesday through a low in the eastern
Pacific ejects some shortwave impulses into the westerly flow that
sets up after this main storm. There still appears to be a break on
Friday...then more showers and thunderstorms for the weekend. Messick
