A very quiet pattern developing for the Twin Tiers. A weak disturbance moving across the area Sunday will trigger a few passing showers and storms Sunday afternoon. Otherwise, high pressure builds in for next week leading to hot, hazy and humid conditions from Monday through next weekend. Maximum temperatures will average in the mid 80s during this period.
Partly sunny skies and mild temperatures will continue through this evening. Diurnal cumulus clouds have developed, which comes with the peak of daylight heating. We will likely see these clouds decrease this evening before more clouds roll in overnight. A weak disturbance to our west will move east on Sunday. Partly cloudy skies will eventually become mostly cloudy by sunrise Sunday morning as that weak storm system passes through.
Sunday will contain more clouds than sun as a weak storm system passes through. Although there will be a tremendous amount of dry time, a brief passing shower or thunderstorm cannot be ruled out during the afternoon and evening. The chance of rain is low-- 30%. Temperatures are on the rise as well and they will max out in the upper 70s to low 80s Sunday afternoon.
High pressure will build in by Monday and it will dominate our pattern all week. This will result in lots of sunshine along with very warm temperatures. In fact, this upcoming week has the potential to be one of the warmest and sunniest stretches of weather so far this summer! Maximum temperatures on Monday and Tuesday will average in the mid 80s across the entire region. Wednesday and Thursday may be the peak for warmth across the Tiers with highs in the mid to upper 80s. If we combine the heat with the humidity, the feels like temperature or heat index will be in the upper 80s to low 90s.
Monday through Saturday look hot with a mix of sun and clouds and mainly dry. There will be a very slight chance of a pop up shower or storm toward the end of the week (Thursday/ Friday), but chance of rain is less than 20%.
