High pressure will gradually build into the region today and the impact of the just-departed coastal storm will diminish as the day goes on. Winds will start the day on the brisk side - though not as bad as yesterday - and they’ll become nearly calm later tonight. With clear skies and nearly calm winds in the overnight, temperatures are likely to drop to the mid and upper 30's by tomorrow morning and frost is possible for the first time in many suburban locations. An area of low pressure with tropical characteristics will pull out of the Gulf of Mexico early this weekend and slide to our southeast by early Sunday. There is a very good chance that this system becomes a named tropical storm (Nestor) and it should throw some rain our way late Saturday night and Sunday. A strong frontal system is then destined to reach us by Tuesday night and it should result in more rainfall for the Mid-Atlantic region.

Last winter began early in the Mid-Atlantic region with significant accumulating snow in many spots before Thanksgiving Day and November turned out to be a colder-than-normal month. The rest of the winter season, however, was fairly mild with temperatures averaging slightly above-normal in the I-95 corridor and snowfall was generally near normal-to-slightly below-normal. In Philly, for example, the coldest month relative-to-normal was November (2018) with monthly average temperatures 3.9 degrees below the normal. The warmest month relative-to-normal turned out to be December (2018) with +2.8 degrees departure from normal. As has been the case in recent years, winter was hard to shake off at the end of the season as there were more cold air outbreaks and even accumulating snow as late as the middle of March.
Numerous factors have been examined for this year’s “Winter Outlook” including sea surface temperature anomalies, solar activity, teleconnection indices, and a comparison with analogous years that featured somewhat similar oceanic conditions. The all-important Pacific Ocean looks like it will feature a large pool of warmer-than-normal water this winter in the northeastern part of the ocean and a weak (slightly positive) El Nino in the equatorial region.

On the heels of yesterday’s soaking rainfall, an intense coastal low will continue to impact the region today with wind gusts of 40-50 mph and scattered power outages are certainly on the table. In addition, today will turn out to be one of the coolest days so far this season with temperatures holding in the 50’s and with much lower wind chill values. The breeze will stick around tonight and Friday and then will die down on Friday night allowing for temperatures to fall into the upper 30’s in some suburban locations. Low pressure will pull out of the Gulf States this weekend and it could produce clouds and rain here later Sunday into Monday.

High pressure will build into the region today and provide us with decent weather as we close out the work week. Low pressure will form over the northern Gulf by this weekend and then pull to the northeast and this system could result in some shower/thunderstorm activity around here. With the increasing chance of some rain this weekend will come a bit of a warm up and temperatures could reach 80 degrees for highs by Monday.

A weakening frontal system will continue to produce some clouds in this area as well as the chance for showers and thunderstorms. By later and on Friday, central Florida may begin to be influenced by developing low pressure over the northern Gulf region and this system will push deeper moisture into the region. As the low pulls out of the Gulf this weekend, it could result in numerous showers and thunderstorms for the Florida Peninsula.

A vigorous upper-level low is dropping southeastward across the Great Lakes today and will interact with a powerful jet streak over the Tennessee Valley to help set off the formation of a strong coastal storm. This low will intensify this afternoon and tonight and will bring a soaking rainfall to the Mid-Atlantic region and the Northeast US – the likes of which haven’t been seen in many weeks. Winds will become an increasing problem as well and could gust past 50 mph later tonight and on Thursday in the Mid-Atlantic/NE US following the departure of the strong storm and possibly to hurricane force along coastal regions of southern New England. As some colder air wraps into the system on Thursday, there is a threat for a changeover to snow in some of the higher elevations of northern New York and New England.

A vigorous upper-level low will drop southeastward across the Great Lakes today and will help to set off the formation of a powerful coastal low along the Mid-Atlantic coastline. This low will bring a soaking rainfall to the NYC metro region today on the order of 2+ inches and the winds will become noticeable as the storm undergoes intensification. The storm will continue to intensify as it rides up along the Northeast US coastline later today into tonight bringing with it heavy rainfall, strong winds and ultimately, even a change to snow in some of the higher elevations of northern New York and New England. Following the storm, winds will be quite strong here on Thursday with gusts to 40 mph and temperatures will struggle to escape the 50's in many spots.

A vigorous upper-level low will drop southeastward across the Great Lakes today and will help to set off the formation of a powerful coastal low along the Mid-Atlantic coastline. This low will bring a soaking rainfall to the DC metro region today on the order of 0.75-1.00 inches and the winds will become noticeable as the storm undergoes intensification. The storm will continue to intensify as it rides up along the Northeast US coastline later today into tonight bringing with it heavy rainfall, strong winds and ultimately, even a change to snow in some of the higher elevations of northern New York and New England.
