October 28, 2012 Leave a comment
Much of the area saw some sunshine this afternoon as the clouds finally started progressing eastward. Cold advection will continue tonight and tomorrow as the pressure gradient increases due to the combination of high pressure to the northwest and very low pressure associated with Hurricane Sandy. Expect blustery conditions during the day tomorrow with 925 mb winds of 30 to 35 knots and solar induced mixing leading to sustained surface winds of 20 knots with gusts to 30 knots possible. A Wind Advisory has been issued for tomorrow as a result. A Wind Advisory could also become necessary for Tuesday as well since similar conditions are expected.
Highs tomorrow could be up to 15 degrees below normal with a slow increase in daily afternoon highs through the next several days. Overnight temperatures should put on the brakes in the mid to upper 30s for tonight and Monday night for most locations as winds will remain in the 5 to 10 knot range during the night. These winds should preclude frost formation until Wednesday morning when winds will relax. The colder spots across northeast Alabama could see lows near freezing on Wednesday and the frost potential will need to be monitored. Dry northwesterly flow will continue over the region into Friday with temperatures slowly rebounding closer to normal by the weekend.
