Regional ForecastSynopsis - Issued 7/3 - 9:35amA cold front will sag through the Northeast today bringing showers and thunderstorms to the region, some of which may be severe. This frontal boundary will stall along the Mason-Dixon line Friday, then slowly return northward as a warm front during the holiday weekend bringing chances for more showers and thunderstorms, especially across the southern half of the region. Weak ridging builds in from the west Monday and early Tuesday as much of the concentrated showers/storms move into New England with isolated diurnal activity elsewhere. Another trough approaches for Tuesday night and Wednesday bringing more widespread precipitation once again.
Short-term - Issued 7/3 - 9:35amClouds and showers along and ahead of a cold front extends over much of the northwestern half of the Northeast this morning, with mainly clear skies to the southeast. At the time of this writing, thicker cloud cover lines up from Altoona, PA to Glens Falls, NY to Caribou, ME. To the south and east of this line enough insolation will occur to modestly destabilize the atmosphere. Temperatures here should warm into the 80's by afternoon but dewpoints will only be in the upper 50's, rising into the lower 60's with moisture pooling ahead of the front. By afternoon mlCAPE rises to 600-1,200 J/kg with muCAPE values approaching 1,500J/kg. Mid-level lapse rates are a paltry 6C/km so the thermodynamic set-up for severe weather is marginal, at best. The best dynamics ride by to the northwest into Canada as well, however, the wind field aloft is still strong. Unidirectional flow from the southwest with a 25-35kt low-level jet, increasing to 40-50kt @700mb and 50-65kt @500mb. Storms will be capable of severe wind gusts as convection mixes these wind down to the surface. Bulk shear of from south to north 30-40kts will organize storms into bowing line segments. Triggers for convection will be forcing along the frontal boundary, a MCV moving out of the Ohio Valley. In fact, a more organized line of convection may form ahead of this MCV as it moves through Pennsylvania this afternoon. To the north, more stratiform precipitation should fall, although there could be an embedded thundershower, before the front clears the region and drier air advects south from Canada. With clouds and precipitation, temperatures here shouldn't rise much from this mornings temperatures as most locales remain in the mid 60's to lower 70's.
Convection continues into this evening, but will be in a weakening phase. Precipitation should continue throughout the overnight from eastern Pennsylvania into southern New England as showers and a few embedded thundershowers. Otherwise expect clearing skies from the north as dry air continues to advance south behind the front. Temperatures will fall back into the 40's over the higher terrain of northern New York and New England! Elsewhere across the interior temperatures will settle into the 50's and 60's from north to south with temperatures holding into the 70's along the southern coastal plain.
