Cold high pressure stays in control today. Really, it looks to stay that way for the next few at least.  Eventually, the jet stream flattens out across the eastern half of the United States, and that spells tranquil weather for the upcoming period.  It’s just too bad it couldn’t be about 10-15 degrees warmer!  Black Friday shoppers: enjoy another day of bright blue skies today before moisture levels begin to climb and we see an increase to our cloud cover heading into the weekend and early next week.

Today (Friday): Not a bad day to get out and take advantage of the deals to kick off the start of the Christmas season or otherwise enjoy the extra-long weekend.  Temperatures remain on the cool side as high pressure over the Great Lakes continues to control our weather. After perhaps some morning clouds particularly north, we’ll have plenty of sun. Less of a breeze, too — only 5-10 mph from the north. That helps it feel warmer even if temperatures struggle up to within a few notches of 40 degrees for our highs. Confidence: High

Tonight: It’s clear and cool as we head through the night, though skies may turn partly cloudy toward morning.  Prior to then, we’ll have had plenty of opportunity to cool off. Overnight lows should reach the low-to-mid 20s across the region.  Winds turn to come from the southeast overnight at around 5 mph. Confidence: High

Tomorrow (Saturday): We’re likely looking at more clouds than sun, thanks to southeast winds and a bit more moisture moving in. That should again hold temperatures down.  If we can break into the sun for a bit, mid-40s are possible, but most spots should find afternoon highs topping out in the upper 30s or lower 40s. Confidence: Medium-High

Tomorrow night: Skies stay on the mostly cloudy side, with a few peeks of starlight coming through here and there.  Sub-freezing temperatures are again likely, as overnight lows dip to the mid-to-upper 20s. Confidence: Medium-High

It’s only fitting that we stay on the cool side as we start meteorological winter on Sunday. On  Sunday through Tuesday, it’ll both look and feel like winter. Well, maybe more fall-like compared to what we’ve recently been through, but still chilled. While we’ll see periods of sun, it looks like the balance of time we’ll see clouds overhead as well.  With no big weather system moving through to boot out this stale cool air mass, it’s in no hurry to go anywhere.  That leaves us with daytime highs only slightly moderating into the mid-40s, maybe a bit higher by Tuesday. Overnight lows are mainly in the upper 20s/lower 30s through the stretch. Confidence: Medium-High
