Chilly Start with a Cool, Damp, Cloudy, Shower Around NYC Today!
Drier and Warmer Weather on the Way!
Drier and Warmer Weather on the Way!
A pesky, slow-moving low pressure system with very strong upper-level support continues to be the primary player in the
weather pattern across much of the Eastern Region... The pool of cold air aloft associated with this system has been quite
impressive --- some of the higher elevations in West Virginia, the western Panhandle of Maryland and across central
Pennsylvania did get some wet snowfall over the weekend... The small, slushy accumulation was limited in most cases to an
inch or less... Even where snow never occurred, many places which are located well inland from the coastal plain yesterday had
a miserable day for early in October; there was intermittent rain, and temperatures were no higher than the 40s... Of course,
most cities and towns that were NOT in close proximity to this upper-level low pressure system weren't as cloudy, and they also
were quite as chilly... For example, it actually reached 70 degrees yesterday in both Hartford and Providence, while
Washington, D.C. and Baltimore were no higher than the lower-50s... We must be on the lookout for a shower or two today and
tonight... Although today won't be cloudy from start to finish, the interaction between some of today's early sunshine and the
colder-than-normal air aloft will make the atmosphere more and more unstable... So, a couple of showers will, in all likelihood,
pop up this afternoon and this evening... Most temperatures will be in the lower or middle-60s... Then, with some lingering
clouds later on tonight, it will wind up in the upper-40s and lower-50s in most locations... Since the improvements in the overall
weather pattern that we're anticipating this week will be 'gradual', we still do think the chances are very good that there'll still be a
few widely-separated showers around here again tomorrow... Not everyone will necessarily encounter a shower, but there will
also be enough cloud cover around to prevent the temperature from climbing all that much... In most cases, tomorrow's
temperatures will verify about 1-3 degrees higher than today's, making it barely noticeable... Folks will still need to grab a light
jacket for the early-morning hours, and keep the umbrella "at arm's length" in case it is needed...
Beginning Wednesday, the transition to a nicer weather pattern will begin... There should be more in the way of sunshine, and
temperatures will experience another small 'uptick'... However, we must be careful in 'how we frame these improvements' in the
future weather pattern for Wednesday, Thursday and Friday... While the upper-level low pressure system will be deteriorating
as it drifts to the east and into the Atlantic Ocean during midweek, the high pressure system building into the Eastern Region
will still only be centered over the southern Appalachians on Wednesday... And the wind flow, both at the surface and aloft, will
be fairly light... Therefore, with a true lack of any decent westerly or southwesterly winds available to transport warmer air into
areas east of the Appalachian Mountains, we can't expect temperatures to make a "significant jump"... Most temperatures will
reach the mid and upper-60s on both Wednesday and Thursday across northeastern Pennsylvania, New York and in much of
New England -- the Greater Philadelphia Area, Baltimore and all points south will probably be in the upper-60s to 'around 70'
both days... This will put us in a more comfortable range than what most of us encountered over the weekend, but I'm just too
concerned that some low clouds and/or fog will develop during the late-night and early-morning hours of Wednesday,
Thursday and perhaps even early on Friday...
If temperatures in the lower or middle-70s are what you desire, then the weekend appears to be the time frame when that will
occur... If the core of the high pressure system that will be taking up residence in the East does manage to sink into the
Carolinas Saturday and Sunday, then temperatures will continue to trend upward -- because a westerly wind will be able to
squeeze out some of that warmer air... In the Plains and across much of the Midwest, temperatures will reach the 70s and the
lower-80s all week long, and it will just take a while for warmth of that magnitude to engulf much of the Eastern Region... By next
weekend, we believe strongly that it will... Have a good day!!!
