The Rain is Back
A large, slow-moving low pressure over the Southeastern United States is creeping northeastward.
Southeasterly flow ahead of the low is bringing moisture from the Atlantic Ocean inland over the Mid-Atlantic.
This moisture is encountering dry air over our region, and most of the shower activity this morning is dissipating over Pennsylvania.
A few stray showers are making it across the border into New York, so while unlikely, a bit of rain is possible this morning.
The high pressure system supplying the dry air will depart the area, allowing rain to make northward progress this afternoon.
Widespread showers are expected to make deeper inroads into the area by the early afternoon and continue for the remainder of the day thereafter.
Southeast winds will increase to around 10 mph this afternoon as well.
Temperatures will be varied across the region, with mid 70s along and north of I-90, much of the region around 70 degrees, and a few 60s in the higher elevations of the western Southern Tier.
Waves of steady rain will persist into the overnight, alternating with periods of more scattered showers. Some particularly widespread rain with a few heavier pockets looks possible in the late evening and early overnight.
As a whole, the rain looks less widespread on Wednesday, with showers gradually diminishing through the day. Therefore, the morning looks rainier than the afternoon, with mainly dry conditions possible by the evening.
Winds will be blustery tomorrow, still coming in from the southeast. Wind gusts will vary with elevation, with lower elevations seeing gusts of 25-30 mph and higher elevations 30-40 mph.
Temperatures will start the day in the upper 50s, but will only rise about ten degrees to the upper 60s with some pockets of 70s.
Late Week Thunderstorms
Warm, slightly humid air will build in for the late week period and the precipitation chances will become more focused on scattered thunderstorms.
Conditions for thunderstorms will only be marginally favorable for thunderstorms on Thursday. These are mostly expected in the afternoon, mixing with some non-thundery showers as well.
No severe weather is expected on Thursday. Highs should reach the mid 70s.
Friday will be warmer and more humid with temperatures near 80 and dewpoints well into the 60s. This will supply ample atmospheric energy for thunderstorm development, but a lack of the winds necessary to organize and strengthen the storms will be a significant limiting factor.
Still, scattered afternoon showers and storms will bubble up and become numerous. Individual storm cells will probably go through their life cycle relatively quickly, limiting any severe weather to isolated, brief instances, mainly of gusty winds or some small hail.
Scattered showers and storms will also be possible Friday night into Saturday morning. Saturday afternoon, however, looks more dry than not with highs in the mid 70s.
Showers will continue to be possible Sunday and Monday, but these rain chances look relatively low at this point in time. If this holds, expect just a few stray, brief showers here and there and a good amount of dry time.
Temperatures will be turning cooler, with highs Sunday in the upper 60s and Monday possibly only reaching around 60 degrees. Nighttime clouds should hold lows in the 40s.
There may be a little dry time around Tuesday or Wednesday next week before rain chances increase again late in the week. Temperatures will mainly remain in the 60s.
