A cool upper level trough is apparent on weather satellite just off the northwest coast this morning, with the speckled nature of the interior clouds indicative of an unstable air mass in the cusp of this trough. Latest weather models are in good agreement and consistent over multiple runs in ejecting this trough inland and through the forecast area over the next three days with today bringing the breezy and gusty transition period as the cold front passes through. High temperatures will be a bit cooler with temperatures this afternoon in the mid to upper 50’s.

On Tuesday in particular, as the center of the trough begins to transit east, just about anywhere in the forecast area will be subject to a shower or two with a 40% chance in the Wenatchee Valley with afternoon high temperature sin the mid 50‘s. The nature of these showers will be typical spring time shallow convective storms with brief periods of rain/snow/graupel and maybe even a rumble of thunder or two in the late afternoon. The most consistently breezy period will be today with gust potential up to 30 mph or so on exposed terrain.

Mostly sunny on Wednesday and for most of Thursday with afternoon high temperatures about normal for this time of year into the mid 50’s.

A wet weather pattern will take Thursday night right through the upcoming weekend with anywhere from a 20-30% chance of rain showers each day with afternoon highs generally in the mid to upper 50’s.
