Days of sub-normal temperatures appear to be winding down. Weekend temperatures here could flirt with 70-degrees amid howling southerly winds expected to gust to 40 mph or higher at times. That huge temperature rebound, while welcome, isn't likely to last very long. Temperatures are expected to be in free-fall by early next week as cold air, predicted to produce sub-zero degree wind-chills and more than a foot of snow in sections of Montana in coming days, spreads eastward.
Wednesday marked Day #13 below normal---the longest string of sub-par days to occur here in more than 3 years.
Temperatures the past six days have failed to warm out of the 40s and the extended cool spell has produced a November 2012 open more than 9-degrees colder than the same period a year ago.
Our prediction of a 52-degree high Thursday would make this the first day in 18 to reach “normal” temperature territory and is just the beginning of a four day temperature rebound expected to last through Sunday.
Mid-Atlantic and New England hit by hurricane force gusts, as well as huge waves and above normal tides--- plus accumulating snow Wednesday; New York’s Central Park records a 4" accumulation
The latest storm to slam the East Coast did so with a decidedly wintry twist.
Not only were winds roaring and did coastal areas witness rising tides and a pounding from 10 to 15 ft. waves for the second time in little more than a week, but snow began falling heavily in New York City north into southern New England late Wednesday. Four inches of snow had accumulated in Central Park by late Wednesday night, while 10" was down farther north at Willingford, Connecticut and 9-inch totals were reported from Monroe, Hamden and Seymour---also in Connecticut. Two inches of snow fell at Elizabeth, New Jersey.
Tides averaged four to 8 feet above normal along the Jersey shore and wind gusts from that area north past Boston reached storm force. The most powerful gust reported reached 76 mph at Cuttyhunk, Mass. Gusts hit 66 and 65 mph respectively at Harwich and Fairhaven---also in Massachusetts.
Possibly thundery Chicago warm frontal passage Friday night sets the stage for a very windy, unseasonably mild weekend; September-level temps will average nearly 20-degrees above normal!
Haze, lows clouds and the areas fog which greet area residents as Thursday dawns are to burn off as the day proceeds, allowing sunshine and temperatures to increase.
Readings in the Chicago area are to reach the low 50s Thursday, the low 60s Friday, and near 70 Saturday and Sunday.
Weather history shows the "typical" year may see another three 60s beyond this date. That same data indicates Nov. 17 has been the historic average first measurable snow date.
Powerhouse storm's front side southerly surface flow to join with south winds at jet stream level to produce potent warming Saturday into Sunday
The new storm rolling out of the Rockies is to produce howling winds here Saturday into Sunday. Those south winds are to blow from the surface all the way into the overhead jet stream, assuring maximum transport of mild air into the area.
A 71-degree high Saturday would tie the 1963 record set in 1949
Various temperature forecast techniques place the odds of a 71-degree high Saturday and a 69-degree reading on Sunday at high levels. Saturday's 71-degree record set 63 years ago in 1949 appears within striking distance thanks to this atmospheric set-up.
Cold air hits Monday shifting rain to snow; wave running up cold front has to be monitored ---sticking snow not out of the question if current computer model scenarios play out
Monday could prove interesting as the area cycles back into cold air. Rain is possible here---and could mix with or change to a period of wet snow either late Monday or Monday night.
