Rain and Wind Are On the Way For This Evening

Good Morning,

As clouds that gathered early last night have broken up across much of the Tri-State Area, most temperatures early today are starting off in the 30s...

There is a high pressure system on this morning's weather map which is in the process of retreating from the Northeast, and it will be drifting into the Canadian Maritimes and eventually the North Atlantic later today and tonight...

Meanwhile, all eyes across the country recently have been on the Plains states... Another powerful winter storm has been producing several inches of snow in parts of Kansas, Oklahoma and Missouri... As that primary wave of low pressure moves into the Great Lakes region later today and tonight, a swath of heavy snow will spread northeastward across Illinois and into Michigan...

But, the rain that will be soaking much of the mid-Atlantic coast and portions of the Northeast very late today, tonight and early tomorrow is going to occur because of the development of a secondary wave of low pressure, albeit rather weak and relatively fast-moving...

Our surface maps show a warm front located in the Carolinas early this morning... And, as that boundary pushes northeastward along the I-95 corridor this afternoon and early tonight, the wave should emerge somewhere near central or eastern Maryland shortly after midnight... Quantitative precipitation totals during the 12-hour period beginning at 7 p.m. this evening and ending at 7 a.m. tomorrow are forecast to be around half an inch, but there will probably be some additional rain tacked on during the balance of the morning, which should push the totals up to around an inch...

There will be locally higher amounts, and flooding of some streets and highways may occur during tomorrow morning's rush... There will be some snow and ice occurring in the higher terrain late tonight and tomorrow morning, primarily north of Interstate 84, and in the Poconos and the Catskills...

As we pointed out yesterday, the somewhat colder vertical temperature profile that the European was showing is supporting a general 1-3 inches of snow and ice from near Kingston, NY on northward... This also applies to Sullivan County in New York State and the higher elevations in northeastern Pennsylvania...

As the area begins to dry out tomorrow afternoon, some strong winds averaging 12-25 mph with higher gusts will begin to gradually subside during the afternoon... Even though there probably won't be any sunshine by day's end, most afternoon temperatures should reach the upper 40s and the lower 50s...

Then tomorrow night, there will be clouds that will tend to linger... The "pesky" upper level low pressure system is going to have a surface reflection associated with it, and it will be meandering across the Northeast (mainly upstate New York) on Thursday and Thursday night...

Therefore, there should be plenty of clouds and a couple of showers around here... Friday will be a windy day with clouds most of the time, and temperatures should begin to trend lower as we head into the weekend...

Have a good day!!!
