FORECAST DISCUSSION
Normal high: 63°F. Normal low: 41°F.
A rather quiet Tuesday on Delmarva leads to some big temperature swings and windy conditions over the next several days that could end up early next week with the coldest temperatures of the season so far.
High pressure is in charge over the Mid-Atlantic Tuesday evening, meaning clear skies and light winds overnight. Good radiational cooling conditions will lead to a seasonably chilly Wednesday morning, starting out in the upper 30s.
As the high slides to the east and a dry cold front approaches from the northwest, we're going to see southwesterly winds becoming increasingly gusty throughout the day Wednesday. Winds could gust to 40 mph or more in the afternoon. Conditions on the waters around Delmarva could become dangerous, with Gale Watches posted for the waters for Wednesday afternoon into Thursday morning. The gusty winds will push afternoon temperatures up to near 70°F.
That dry cold front crosses Delmarva Wednesday night, leading to a wind shift to the west-northwest and a significant drop in temperatures. Thursday, while mostly sunny, will feel almost blustery at times, with afternoon highs likely not climbing out of the 50s thanks to the gusty winds.
Temperatures will recover as we head into the weekend, with highs in the seasonable low 60s Friday, climbing into the upper 60s by Sunday. A series of rather weak cold fronts will keep low chances for stray showers in the forecast all three days, but no day is expected to be a washout.
A stronger front Sunday night will usher in a deep upper trough that could bring our coolest temperatures of the season so far; temperatures next Monday might struggle to get out of the 40s with a gusty northwest wind.
In the long range, temperatures are expected to average below normal, and precipitation near normal for November 11 - November 17.
