.SYNOPSIS... Frontal boundaries sweeping through the region during the next couple of days will bring periods of rain to Central NY and Northeast PA from tonight through Thursday evening. High pressure will return partly to mostly sunny conditions this weekend while attention then turns toward a couple of tropical systems moving north along the East Coast.
&&
.NEAR TERM /THROUGH THURSDAY/... Rain chances will increase through this afternoon and tonight as a warm front lifts into the region by Thursday morning. No significant impacts are expected from this much needed rainfall after prolonged dryness. As we progress deeper into the warm sector on Thursday instability parameters and shear do marginally come together for the potential for stronger convection on Thursday. Can`t completely rule out strong thunderstorm induced wind gusts focusing primarily from the Catskills down into the northern Poconos corridor. This is also the area where the highest axis of anomalous moisture is depicted with PW anomalies around 2 SD. Probabilities suggest high chances for more than an inch in this area with low- moderate chances of exceeding 2 inches...but those values should be isolated. River and smaller stream response will be slow to this rainfall, but urban ponding in common low lying areas can`t be ruled out.
&&
.SHORT TERM /THURSDAY NIGHT THROUGH FRIDAY NIGHT/... Much of the steady rain activity will shift into New England on Thursday night but lingering showers will remain in the forecast until the supporting upper trough and surface cold front pass early Friday. Broad scale synoptic drying appears to take shape in the models on Friday...but with NW flow across Lake Ontario we`ll have to remain vigilant for lower level cloudiness and the potential for sprinkles lasting longer than indicated by the guidance in CNY. Downslope flow into NEPA should make for a better day overall in that part of our forecast area. The airmass behind the cold front is not excessively cool therefore seasonal temperatures are expected.
&&
.LONG TERM /SATURDAY THROUGH WEDNESDAY/... The bulk of ensemble data shows high pressure building into the region with a fairly quiet period offering quite a bit of sunshine and warm weather into early next week. Focus turns toward some model guidance chaos as the predictions struggle to resolve a couple potential tropical systems moving through the Western Atlantic. Blended NBM guidance is playing the safe game by introducing low probabilities for showers across NEPA on Saturday and Sunday, and then again later Tuesday into Wednesday. Consensus among the ensemble means suggests that heights in the northern stream are to remain above average over the northeast with a tendency for developing troughing over the Canadian Maritimes during this period which should favor suppression of these tropical systems. Overall confidence in this period is quite low and at the very least we`ll have to be closely monitoring for northward surging of tropical moisture plumes.
&&
.AVIATION /00Z THURSDAY THROUGH MONDAY/... Rain showers will continue to spread eastward tonight and eventually lead to lower visibilities and ceilings. All terminals will fall to at least IFR. There are some periods that guidance favors LIFR ceilings and as well at most terminals. There may be a break in shower activity early Thursday morning but it will be brief and ceiling restrictions will remain in place through the TAF period. AVP, ELM, and ITH may improve to Fuel Alt/MVFR late Thursday afternoon as rain begins to move out.
Winds will be southeasterly and breezy tonight. A front then moves through and winds then become southwest to westerly by Thursday afternoon. Behind the front, winds become calmer.
Outlook...
Thursday Night...Showers moving out; restrictions linger.
Friday through Monday...Mainly VFR.
