Sunday Morning National Radar – College of DuPage

A storm system exiting the four corners region is intensifying over the Great Plains this morning. This storm is dominating the forecast for the next couple days as evidenced by the current hazards outlook from the National Weather Service.

Current Hazards Map – NWS

Consistent with many early spring storm systems, heavy snow and occasional blizzard (pink and purple) conditions are expected north of the storm center while a severe weather outbreak is expected across Dixie Alley (see below). Further northeast across the Great Lakes and Northeast states, High Wind Watches (golden yellow) have been issued for tomorrow.

SPC Day 1 Convective Outlook

The Storm Prediction Center in Norman, Oklahoma has issued a large Moderate risk (level 4 of 5) for today’s severe thunderstorm potential across the southeast. The ongoing convection across eastern Texas in the radar loop at the top, will grow and mature downstream in an environment favorable for damaging thunderstorms, including tornadoes.

Sunday Afternoon Temperatures – WeatherBell, LLC

A rather delightful Sunday is in store for the northeast today with temperatures approaching 60 F for southern and central New England. Cooler temperatures across Maine where snow still covers the ground.

Monday

As the storm system across the southeast matures and moves north it will create a very wet and windy Monday for New England.

Monday Simulated Radar Loop – College of DuPage

Early after Midnight heavy rain and downpours will move up from the south and be with us for most of the day.  During the afternoon the rain will become more scattered in nature and an occasional rumble of thunder may be heard.  At the same time, a strong low level jet will move through the region.  Winds just above the surface will be quite strong.

925 mb Wind Speeds Monday Afternoon – College of DuPage

Wind speeds only a few thousand feet above the surface will be roaring along at upwards of 100 mph. During the heavy downpours, these winds may mix to the surface and cause damage. Below is an image from the NWS Boston office with anticipated wind gusts tomorrow.

Monday Wind Gust Potential – NWS Boston

The potential for power outages is relatively high tomorrow, especially the further south and east one resides.

Rest of the Work Week

The remainder of the week looks relatively quiet. An ocean storm passes far enough offshore that little precipitation is expected.  Overall temperatures still look relatively cool with highs in the 50s for the most part. Maybe teasing 60 for a day or two.

Another central and northern New England snow threat for the weekend?
