Grab Your Blanket

As winter approaches, the days and nights grow colder and colder as the sun’s position above the horizon gets lower and lower. At night, the temperature is also dependent on the presence of clouds. On a clear night, radiation from the earth’s surface escapes efficiently to space. On a cloudy night, the clouds act as a blanket that traps radiation. Tonight, as the clouds clear out, temperatures will plummet into the upper 30s°F, the coldest night we have seen yet this fall. Temperatures this week will be generally colder than average, as cold air from the north dominates our region.

Rain showers will end this afternoon, followed by cold, dry weather Wednesday and Thursday. The chance for rain returns Friday, with continued below average temperatures.
