Real WX Services Level 3 Alert For Late March 31st into the 1st Of April.

As we have been talking about some time now ..the region is getting ready to deal with a Spring Season Nor’easter that is going to have more Winter like effects over parts of the region.  This forecast is based on a blend of the ECM/ECM means and the GFS Means.

Low pressure is going to develop off the coast of Hatteras and move up and along the eastern Seaboard. If you are generally along the coast you can expect rain out of this system and in the order of 1-2 inches depended on where you are located.

Before this happens however..another area of low pressure may bring some QPF into the region starting later this evening and that will probably be in the form of rain..if you are in higher elevations it is possible that this may take a more wintery form. The real show though is going to be on Thursday Night into Friday…

As this low pressure moves up the coast it is going to deepen rapidly. This will allow dynamics to come into play with the upper levels being colder will pull the colder air down towards the surface resulting in locations going from rain to a heavy wet snow. This is the type of snow that will cling to trees and powerlines so it is possible that locations may lose power as well as have some fallen trees.

Winds will be another issue as they may be in the range to 15-25 MPH with gusts as high as 35 MPH which in heavier snow will cause visibility problems.

final

As usual this time of the year the highest amounts will be in the higher elevations. Because this show will be falling in the overnight hours it is also very possible this will cause some slippery roads. Majority of the accumulations should be however on the grassy areas.

Stay tuned as the models still remain in less agreement then they should be.
