One More Day of Mild Weather Today
But Following 7-10 Days Look Cool

Josh Larson @ 10:00 AM

We'll look for one more day of mild temperatures today, but a cold front that will move through later today will bring noticeably cooler temperatures for Friday and the weekend. By the start of next week, a reinforcing shot of cold air will build into the region, likely keeping our temperatures below normal through at least the end of the work week.

Today


Confidence: HighPartly cloudy; mild. Though at times we may see more clouds than sun, especially during the first half of the day, as a cold front pushes through, southerly winds should allow high temperatures to near 70. Late in the day, winds will shift to out of the NW along with partial clearing by sunset. Clearing and cooler overnight, with lows from the upper 30s to the mid 40s downtown.

Friday


Forecast Confidence: MediumNoticeably cooler. In the wake of today's frontal passage, temperatures on Friday will be some 10+ degrees cooler under mostly sunny skies and breezy NW winds 10-20mph at times. Look for high temperatures in the mid to upper 50s with clear overnight skies allowing for overnight lows to drop into the mid 30s to the low 40s downtown.

The Weekend


Confidence: High-Very HighPleasantly crisp. With high pressure firmly under control on Saturday, look for abundant sunshine with high temperatures within a couple degrees of 60 and overnight lows in mid 30s across the coolest suburbs to low 40s downtown. An upper-level area of low pressure looks like it will bring plenty of clouds to the region on Sunday with a slight chance of a sprinkle in some spots. High temperatures will stay in the mid to upper 50s with overnight lows from the upper 30s to mid 40s.

Pattern Overview


Though the first day of November (today) will feature temperatures nearly 10 degrees above average, a cold front will cool temperatures to slightly below normal levels for Friday through the start of next week. And by Monday it looks like a strong trough will build into the eastern US, which is likely to bring a reinforcing shot of cold air that will bring the coolest temperatures we've seen so far this season. I would not be too surprised if high temperatures don't make it much above 50 degrees by the second half of next week. Bottom line: after today it looks like we'll see a period of at least 7-10 days of seasonably cool (and largely dry) weather.

Pictured: the GFS forecast model predicts a strong trough of low pressure over the eastern US by Tuesday of next week; note the cool 850mb temperatures seeping into the eastern US from Canada, which will lead to below normal temperatures for our area.

LARSON'S LONG-RANGE


Next week's forecast
Forecast highs/lows: 56/39 (normal = 60/42)
Forecast precip: Below-normal

Confidence: High-Very High Look for mostly sunny conditions on Monday with high temperatures in the upper 50s and overnight lows mostly in the 40s. Tuesday looks to feature continued mostly sunny skies with highs near 60 and cooler overnight lows ranging from 30-40. The forecast for Wednesday calls for partly sunny skies, breezy conditions and cooler afternoon highs in the mid 50s with overnight lows in the 30s. From this far vantage point, the outlook for Thursday and Friday calls for partly to mostly sunny skies with high temperatures from 50-55 and overnight lows in the 30s once again.
