PM Update: After another mild day, cooler tonight and Thursday Posted at 05:00 PM ET, 12/05/2012 Much of the area set high temperatures overnight before cooling a bit around sunrise, then slowly climbing again throughout today. Afternoon readings in the 50s to near 60 are still above normal, though not quite as much as our really warm days of late! You'll certainly notice the cooler air filtering in as we get into the evening, and we've got a colder than normal day tomorrow, but that doesn't look to last long as warmer air is already on the horizon. Through Tonight: It's brisk out there as temperatures fall off more than recent nights, and winds continue to blow around 10-15 mph, particularly early night. Those winds decrease around and after midnight though, and skies are mostly clear throughout. Lows make it to a range between the upper 20s and mid-30s. Tomorrow (Thursday): We won't have anything to think about weather-wise except for chillier temperatures. Skies are mostly sunny, and winds aren't too bad either, only around 5 mph with some higher gusts most of the day. While it's much cooler than it has been recently, highs largely in the mid-40s aren't otherwise overly notable this time of year. See Dan Stillman's forecast through the weekend. New storm sensors: Remember last week's atmospheric river? Well, a new suite of storm sensors should help forecasters better expect impacts along the West Coast. As atmospheric river storms are responsible for about 25-50 percent of yearly rainfall in some areas, any additional data should be valuable. The first portion of the network is expected to be installed in California later this month.
