Premium weekly outlook: Very warm start, cooler air to follow

/by

The anomalous warmth we spoke about last week? It’s finally here! Sunshine will mix with clouds occasionally this afternoon, but by and large, high pressure will remain in control of the weather throughout the Northeast United States. Forecast model guidance suggests that 850mb temperatures of 12-14+ C will surge northward toward the Mid Atlantic states, with southwest winds drawing in warmer air at the surface. Temperatures will rise in the upper 70’s to near 80 this afternoon, with the possibility of some clouds later this afternoon and evening as a weak disturbance passes by. Otherwise, clearing is expected later tonight underneath high pressure and light winds. The interior valleys will drop into the 50’s, but this will be much warmer than the past several nights. Radiational cooling and warm air advecting in the mid levels could cause moisture to be trapped in the low levels — leading to low clouds and patchy fog in spots through Tuesday morning.

Sunday Overview: Warming Trend For Early This Week

/1 Comment/by

A beautiful Autumn weekend continues today, with high pressure still in control. But a warming trend will start today with more southwest winds, as high pressure begins to shift further south and east of the region. Highs will be in the upper 60 to lower 70s with plenty of sunshine today. These temperatures are already slightly above normal for this time of year. Clouds will be on the increase tonight as a weakening cold front approaches the region.  Some isolated or widely scattered showers are possible later tonight and tomorrow morning.  But with limited lift and moisture, these will likely be on light side.

The cold front likely washout day during the day tomorrow, as ridge from the southwest, begins building over the region. Clouds should break for more sunshine by the afternoon and unseasonable warm airmass will be in the region with temperatures well above normal. West-southwesterly winds will cause temperatures to rise into middle to upper 70s to near 80 over many parts of the region tomorrow afternoon. Some other highlights, for this upcoming week:

Monday Musings: Cold air, high pressure settles in

/by

Behind the ever-surprising Hurricane Matthew, which offered a last-minute change in track this weekend after several before that, high pressure and more benign weather will finally settle in during this week. While many are taking the day to relax, in recognition of Columbus Day, the chill and blustery winds have the air feeling just like Autumn should, if not a bit colder compared to average.

Much of the same is expected this evening, as the cold airmass settles overhead. High pressure will bring clear skies and calming winds, which will set up ideal radiational cooling conditions throughout the area tonight. We’ve got the highlights below:
