----------------------------------FORECAST----------------------------------
TONIGHT - A few passing showers is possible around NYC and Northern Suburbs tonight, while a wave of low pressure moves to the north and brings sleet wet flakes on the CT/MA border and heavier snow North and Northeast in Interior Northern New England. Temps in the mid 30's to high 20's in Maine.
THURSDAY - Cloudy, maybe a few rain showers on and off throughout the afternoon. Highs in the mid 40's.
FRIDAY - Partly to mostly cloudy with a chance of scattered thunderstorms in the morning and afternoon, very good chance of getting well into the 60's on this day, 60-65° seems very plausible and maybe even close to 70°.
SATURDAY - Sunny with clouds moving in and out...so lets say partly to mostly cloudy? Highs in mid 40's to maybe 50°.
-------------------------FORECAST DISCUSSION-------------------------
Highlight of the day...SEVERE WEATHER! Ya not here, but man do we have some interesting stuff going on out in the Plains. What we got is a stalled out frontal Boundary going right across the country from Colorado to Ohio to the Carolina's and to us. You can see it in the pictures I have below. This stalled out boundary also happens to be right smack on the edge of the Pacific jet, and it started ushering in waves of low pressure and NRG and it just keeps on giving wink emoticon. So we get a frontal boundary, a jet giving tons of moisture off the Pacific, warm gulf air being sucked up north, Cold air to the North of the Front...recipe for disaster!


So today we got the nice frontal boundary out west draping through ESE Kansas, west Oklahoma, western Texas and into Missouri. Along with it we have the dry-line located right to its west. Advantage today is that there is little warm air aloft along the dry-line, and Lapse rates, CAPE, wind shear among other items are inline and good for spawning severe thunder storms and tornado's. We can see several areas in SE Kansas, Missouri, even a bit in Kentucky where we have supercells forming. Lets see if we can get a tornado outta one. One thing that was noted is that with little convection over last night and today, the actual frontal boundary lifted north a tad. So, NCEP and other sites have changed their ideas a bit north as well with it. Main show starts this evening and into the nighttime (Late afternoon for them in the plains) as the main bulk of NRG comes in behind the initial upper level disturbance. If winds back off and stay back as the Upper low deepens this afternoon, then thats when we start really seeing the tornado's form. But one step at a time.
NOW, for us here in the NE...the jet will continue to bring in waves of low pressure until Friday night as it all moves out and the HP to our north begins to back off and let the jet resume to its normal moving position. Things should really start to warm up next week, looking like multiple days into the 60's and maybe 70's...do we even see an 80° day late next week? Could be!
CIAO for now!
