Today’s
Northeast weather discussion.
The surface shows
a few shortwave troughs and that moisture starved cold front moving through;
radar is showing a few isolated showers, but that’s about it. Temperatures ahead
of the front will be mild. Behind the front seasonal temperatures will return
for the next couple of days.
Tuesday into
Wednesday a warm front will lift into the region. With the front temperature
will temporarily warm along with some rain showers.
The pattern
change.
A Feature in
the polar jet around Hudson Bay, is going to slide south and east into the Gulf
of Maine, this will then act as a block, forcing the system in the southern Plains
to move into the Midwest then force it to reform over eastern Pennsylvania or just
off the Coast, then it will move over New York State into northern New England
and Canada. This will bring rain showers later in day on Wednesday for western
parts of the region, the cold front will continue to move east during the night
into Thursday. This will be bringing
needed rain to a large part of the region. General rainfall amounts look to be
0.50 to 1.25 inches but there could be localized amounts of around 2 inches.
Colder air will be streaming in behind the front, this will bring snow to the Appalachians, and will change rain over to a mix for some of the lower elevations, with a mix/snow for the higher elevations, later Thursday into Friday morning. The higher elevations of New York State and northern into Central New England could see measurable snowfall. Who sees the mix will depend on how much cold can get in here and the exact track of the low.
The colder northwest wind coming over Lake Erie and Lake Ontario, will support some Lake Effect snow bands for Saturday into Sunday. Those Southeast of the Lakes should see some measurable snowfall. How much will again depend on the temperature profile over the Big Lakes. There could be a decent amount snow in localized spots of the snowbelts, but right now it doesn't look to be a blockbuster event.
The cold pattern
coming will be stick around for a while, so cooler temperatures will be
generally in store for 7-10 days. Then we should see the pattern for mid-December
take hold that I talked about in the Winter Outlook.
Tropical discussion
Sara has dissipated,
and is no lower being tracked by the NHC. Her remnants will bring heavy rain
for the northern Gulf Coast as well as Florida.
A little snow would be nice.
ReplyDeleteI have to reread the winter outlook
ReplyDeleteI thought that it was going to be cold for December.
