Much Cooler Air Pours in After Rain Stops
Below-Normal Temps Linger Thereafter

Josh Larson @ 12:05 AM

Today's morning rain will taper off by early afternoon as a strong cold front barrels through the region. In its wake we'll see windy conditions and falling temperatures for the remainder of the day. It looks like below-normal temperatures will linger until at least the first half of next week, but any flakes during this period will be confined to the mountain areas.


Confidence: HighRainy AM; windy & cooler PM. Look for cloudy skies and periods of rain along with temperatures in the low to mid 50s through the early afternoon. After the cold front clears the area we'll see partial clearing and gusty westerly winds 15-30 mph along with temperatures falling into the mid 40s by evening rush. Becoming mostly clear and breezy overnight, with lows dropping to the low to mid 30s in most spots.


Forecast Confidence: MediumSunny, breezy & cold. As strong high pressure builds into the region Friday behind today's cold front, we'll look for abundant sunshine, breezy NW winds 15-25 mph and high temperatures struggling to eclipse 50 degrees; it will feel even cooler in the shade or when the wind blows. Clear and quite cool Friday night, with lows ranging from the upper 20s across the coolest suburbs to the mid 30s downtown.

The Weekend

Confidence: High-Very HighSeasonably cool. With high pressure in control this weekend, we'll look for dry weather, partly to mostly sunny skies (and mostly clear nights) along with cool temperatures. We'll look for high temperatures within a few degrees of 50 degrees both afternoons along with overnight lows ranging from the low 30s across 'burbia to near 40 downtown.

Pattern Overview

The main weather story over the next week or so will be the much cooler temperatures behind a strong cold front which will push through the area today. A trough aloft will establish itself over the northeast over the next several days, and as strong high pressure builds into the area on Friday into this weekend, we'll generally see temperatures some 5-8 degrees below normal (especially the daytime highs). Cooler than normal temperatures will linger through at least the first half of next week, but there are indications that milder temperatures -- closer to their seasonal norms -- will return in time for Thanksgiving.

Next week's forecast
Forecast highs/lows: 53/40 (normal = 55/38)
Forecast precip: Below-normal

Confidence: High-Very High Look for partly to mostly sunny skies on Monday with high temperatures in the low 50s and overnight lows ranging from the mid 30s to the low 40s. Tuesday and Wednesday should feature times of clouds and sun with slightly milder temperatures in the low to mid 50s with overnight lows ranging from the mid 30s to low 40s. From this far vantage point, the outlook for Thursday and Friday calls for mostly cloudy skies with a chance of rain both days along with highs in the 50s and overnight lows in the 40s.
