Another cold frosty morning this Wednesday with clear skies, dry air and light winds. Temps bottomed out in the teen and twenties early this morning. Sunshine with a light SE wind through the afternoon will see temps rebound into the 40's to near 50. Some increasing high clouds during the afternoon. High pressure will be pulling off the coast with a milder wind from the south Wednesday night with increasing and thickening cloud cover overnight. Clouds will be in place Thursday with temps gradually rising into the Lwr 50's by the afternoon under a developing southerly breeze ahead of an approaching cold front with incoming rain.
A light rain or showers will develop ahead of the cold front during the mid afternoon hours on Thursday. A steady rain will overspread the region Thursday night through early Friday morning. The heaviest rain will likely happen during this time through Friday's morning commute. Rain will be ending Friday morning, but it could take until the midday depending on a wave of low pressure along the front which would keep the rain going much of the morning. Either way, it will be a good soaking rainfall with upto .75" to 1.5" of rain expected. A drier Friday afternoon with some breaking sun across the interior and highs still holding around 50-54 degrees, before cooler air arrives Friday night and Saturday.
A weak area of high pressure will be close enough to us to make for a sunny day Saturday with high clouds and cooler highs in the mid 40's. Another weak front will approach Saturday night and early morning hours Sunday. This may kick off a few rain or snow showers with it's passage. Some accumulating snows will be possible in our Northern mountains. Breezy cold WNW winds following in behind this front will give Sunday a brisk chilly feel with partly sunny skies. A cool upper low will swing in for the afternoon, promoting clouds in the mountains and interiors. Breezy NW upsloping winds will keep the snow showers going in the mountains where several inches of snow will be possible by Monday morning. A cold shot of air will be in place for the Monday Tuesday time frame with highs struggling to get into the Lwr 40's for highs.
If you are wondering about Thanksgiving, it is is looking fair and sunny with a moderating airmass from the early week chill. High pressure over the Canadian maritimes and Light onshore winds with highs in the 40's and Lwr 50's possible inland.
