WHAT HAS CHANGED
- 6 AM Update to Aviation section with 12z TAFs
- The rain system next week looks to arrive later, possibly beginning Tuesday evening
KEY MESSAGES
1) Dry weather with above normal temperatures through the weekend under high pressure.
2) Potential for a system moving in early next week, bringing another round of wetting rainfall.
DISCUSSION
KEY MESSAGE 1...Dry weather with above normal temperatures through the weekend under high pressure.
KEY MESSAGE 1 DESCRIPTION...
The ridge of high pressure will keep winds light, skies mostly clear and temperatures above normal through the weekend. Highs will be in the low to mid 80s this weekend for inland locations, and cooler along the coast with a sea breeze developing each afternoon. Cannot rule out early morning patchy river valley fog with radiational cooling.
KEY MESSAGE 2...Potential for a system moving in mid next week, bringing another round of wetting rainfall.
KEY MESSAGE 2 DESCRIPTION...
High pressure lingers over the region this weekend, as a low pressure system slides off the east coast early next week.
Generally, low pressure east of the Carolinas moves northeast in the Atlantic, east of Nova Scotia. To the north, another low pressure over Canada moves eastward, with a cold front that will approach our region Monday but likely stall before reaching us.
Meanwhile, low pressure over the Great Lakes region will move east towards the area early next week bringing the greatest chance for wetting rain between Tuesday night and Thursday. Some thunderstorms are also possible with this system. Ensembles currently show a 50-60% chance of at least 0.5" of rainfall.
