Premium Weekly Outlook: More active, progressive pattern this week

/1 Comment/by

Good morning and happy Monday! Overall it was a beautiful weekend, especially as lower humidity settled into the region on Sunday. But a more active, progressive weather pattern is expected this week. This comes as a strong heat ridge begins building over the Rockies and Western Plains this week and the AO/NAO remains positive with lack of high-latitude blocking. This pattern will allow some ridging to build into the region this week with heat and humidity building. Multiple disturbances are expected to move from the Great Lakes/Ohio Valley through the Northeast and Mid-Atlantic, with threats for showers and thunderstorms this week.

First off,  high pressure will be moving off the Mid-Atlantic coast, with a return southerly flow developing over the region today. Mostly sunny skies are expected this morning, then some clouds will be increasing and filtering the sunshine as a warm front approaches.  Humidity will begin increasing later this afternoon as dew points rise into 60s. More lift and instability ahead of warm front may lead to a few isolated showers or thunderstorms popping up over the region later this afternoon. Temperatures will rise into lower to middle 80s area wide. South-southwest winds today will allow for sea-breezes to keep coastal sections in the 70s much of this afternoon.

Premium Weekly Outlook: A Look into Christmas and Hanukah Weekend

/by

After brief mild surge in the 50s over much of the region yesterday, another artic airmass has moved back over the region today. Despite only some high cirrus filtering sunshine, temperatures for the rest of this afternoon will likely only reach the lower 30s. This is airmass is not cold as last week. But it’s another reminder that we are still only in December.

Another very cold night is store for tonight. High pressure building over the region, will result in mostly clear skies and calmer winds later tonight. This will allow for more radiational cooling, especially for the suburbs.  The only cavet for ideal radiation cooling conditions will be with more high clouds early tonight with a weak shortwave trough passing through. But these clouds should move out overnight.  Temperatures will likely drop well down into the teens and lower 20s over the much of the region. Some of the interior valleys and the Pine Barrens may drop into the signal digits, if skies clear out enough.
