JAMESTOWN – Showers and thunderstorms will develop tonight into tomorrow morning with a chance that a couple of those storms could be on the stronger side with increasing humidity.
The NOAA Storm Prediction Center has outlined all of Western New York and Northwestern Pennsylvania under a standard Slight Risk, a level 2 out of 5, for tonight.
The SPC also has a Slight risk in place for much of the Southern Tier and Northwestern PA again for tomorrow morning.
There still could be a brief shower this afternoon, otherwise just lots of clouds around with a few peaks of sun possible. There still will be a stiff southernly wind. Highs 68 on the hills, 74 at the Lake Erie shoreline.
The first line of showers and thunderstorms will enter the region from the north, first starting out near Buffalo and sagging southward into the Southern Tier by around 11 p.m. These storms will have the potential to produce very heavy rainfall and brief gusty winds.
These storms will move south through the region overnight and clear out of the area by around 2 a.m. After a break in the action, the second line of storms fire west to east around 5 a.m. and clear the area by 9 a.m.
Once again, these storms could have the potential to produce torrential downpours along with brief gusty winds at times. The humidity will also be on the rise overnight as well, with lows staying in mid to upper 60’s for most of region.
After morning showers and storms, the remainder of the day will be mainly dry with only a small chance for a shower or thundershower before the afternoon. It will be a bit muggy with highs in the mid 70’s.
The humidity creeps up a little more on Thursday with a good amount of sunshine and highs near 80.
Throughout the afternoon on Friday, widely spaced showers and storms will be possible due to the daytime heating and high humidity. Highs in the lower 80’s.
High pressure returns over the weekend with a gradual shift in the upper air winds bringing in cooler and more refreshing air. Both days will be partly to mostly sunny with highs in the upper 60’s to lower 70’s.
Next week will start dry and seasonable with a good amount of sunshine and highs in the lower 70’s.
