AFTER A VERY WET COUPLE OF DAYS, DRY AND COLD WEATHER MOVES INTO THE MID-ATLANTIC STATES JUST IN TIME FOR THE THANKSGIVING HOLIDAY WEEKEND… A SLOW MODERATING TREND IN TEMPERATURES IS EXPECTED LATER IN THE WEEKEND

The low pressure system that brought all the wet weather on Tuesday and Wednesday is moving through the Canadian Maritimes. It is now a deep cyclone¬†as there are numerous isobars surrounding the system. Isobars are lines of equal barometric pressure. The more isobars that surround a cyclone, the more intense the storm is. Rainfall totals in my Virginia Beach neighborhood were around two inches. However, well to our west, there were much higher rainfall totals. Winds were quite strong especially on Wednesday afternoon as the low began to pull away. Winds are much lighter now as high pressure builds in. It’s a cold high so temperatures this Thanksgiving Day are going to be below normal. There’ll be lots of sunshine, however. Temperatures will slowly moderate and by Sunday, highs should be closer to normal. There is some uncertainty in the extended forecast as computer models differ in the location of an expected low pressure system developing off the Carolina coast. The exact position and intensity of this potential system will determine our weather early next week. I’ll have an update on Saturday.
