050 FXUS61 KCTP 022324 AFDCTPArea Forecast Discussion National Weather Service State College PA 724 PM EDT Thu Oct 2 2025
.SYNOPSIS... * Temperatures will climb to well above normal Friday into early next week. * Our extended dry pattern continues with no rainfall and low humidity expected through Monday night. * Cooler for later next week.
&&
.NEAR TERM /THROUGH FRIDAY/... A large high pressure will remain in control into Friday. The airmass is quite dry, so the potential for fog is low tonight. A few high clouds extended southward from Canada into central PA. Light winds and nearly clear skies will make for radiational cooling. There could be a few spots with temperatures falling into the upper 30s.
&&
.SHORT TERM /FRIDAY NIGHT/... Main features to the forecast are dry aftn dewpoints/low humidity, but just a little higher Fri vs Thu, and temps trending above normal. Even though the dewpoints rise, expect lows Friday night to quickly fall off after sunset.
&&
.LONG TERM /SATURDAY THROUGH THURSDAY/... A large upper level high will prevail, as was the case back in September.
Earlier discussion below.
Thus mostly sunny and very warm days followed by comfortable sleeping nights over the weekend into early next week. Highs will climb well above the historical average for early October (+10-15F) reaching the mid 70s to low 80s. The dry air in place will keep min temps closer to/but still above climo. No rainfall is expected Saturday through Monday.
Model and ensemble mean consensus finally bring some rainfall back into the picture by the middle of next week, with a cold frontal passage projected around next Tuesday/Wednesday. NBM/WPC blended QPF amounts within that 24 to 48 hr period are in the 0.10 to 0.75" range from SE to NW - so certainly not a drought buster we will take what we can get.
&&
.AVIATION /00Z FRIDAY THROUGH TUESDAY/... Other than a few high clouds extending southward from southern Canada, expect clear skies overnight.
Dewpoints remain low, so not much chance of fog tonight or Friday night.
The dry high pressure will linger over the eastern half of the CONUS through the weekend, providing excellent flying conditions.
Outlook...
Sat-Tue...VFR other than AM fog possible mainly - N valleys.
&&
.CTP WATCHES/WARNINGS/ADVISORIES... None.
