Monday - Oct 26, 2026 @ 6 AM EDT: Aside from a weak, dry cold front drifting SE across the state later today and another similar one on Friday, generally above to well-above normal temps will occur through Saturday with no rain. Friday will likely be the warmest day of the week.
500 PM Sunday October 25th, 2026: Several warm days are in store for central PA late week, with Friday being the warmest day. No rain expected this week.
Sunday - Oct 25, 2026 @ 630 AM EDT: High pressure will dominate our weather with rain-free conditions continuing through the end of October and likely for the first few days of November.
Only a minor dip in the mild late Oct temps will occur behind a weak cold front Tue and Wed.
555 PM Saturday October 24th, 2026: With an upper level ridge to the west of Pennsylvania over the much of the next week or two, a tendency to stay in a rather dry northwest flow of air will aid in keeping central PA rainfall near normal and wet across the southwest states.
It's not unusual...to have a long, dry stretch of time in Autumn. The top 10 driest stretches (no measurable precipitation) for Harrisburg (#1 is 35 days) and Williamsport (36 days):
Saturday - Oct 24, 2026 @ 545 AM EDT: After a chilly start, this weekend will feature near perfect weather for outdoor activities, yard work and travel with abundant sunshine, low humidity, excellent visibility, light wind and near to slightly above normal temperatures.
420 PM Friday October 23rd, 2026: As the end of October nears, and we head into early November, much of eastern part of the country and Pennsylvania are expected to be warmer than normal.
A very dry Canadian airmass will spread south over the state today with precipitable water (first loop) dipping to below 0.25 inch and just some high clouds (second loop) streaming SE this aftn and evening. Also included here is a time section of temp and precip at Harrisburg.
A moisture-starved cold front will bring some clouds to areas north of I-80 this evening into Friday morning, but no expected rainfall. These clouds will keep temperatures slightly warmer tonight compared to previous nights across the northern tier. #PAwx
☀️🍂Repetitive Fall pattern rolls on with another seasonably sunny day across CPA
🗓️Dry & seasonable weather lasts into the final days of October; no rainfall forecast through at least 10/28
🌕The Hunter Moon rises around sunset on 10/25 & reaches full phase at 12:11 a.m. 10/26
Subtropical storm Josephine has gained enough strength to become a named storm, but will stay far enough off the coast that no impacts from this storm are expected for central PA. The storm will continue to strengthen over the next day or so then turn eastward into the Atlantic.
🌠Great viewing conditions expected in central PA
Get out if you can and enjoy this incredibly long string of dry, sunny and mild late October weather. Aside from a stray, light sprinkle across the Northern Mountains of PA late Thursday or Thu night, a zero percent chance of measurable rain will occur through at least Sunday.
High pressure will remain in control for the rest of this week and into the weekend. Mostly clear skies and seasonal temperatures will be forecast through Sunday. High temps this week will remain largely in the 60's every day while we remain in this high pressure regime.

It's time for your Week 3 Fall Foliage Report! 🍁🍂
While heavy rain knocked down some leaves, chilly nights recently sped up the color change in many Pennsylvania forests.

Did you know that fall is one of PA’s peak wildfire seasons?
Plentiful combustible fuels (leaves, sticks, etc.), bare trees, fluctuating relative humidity, and increased human activity all contribute to a heightened risk of wildfires.
Learn more: pa.gov/agencies/dcnr/program…
ALT Bare trees in fall let sunlight dry forest floors, increasing wildfire risk with abundant combustible fuels like leaves and sticks.
Spectacular early Autumn weather will continue for at least the next 7 days thanks to persistent high pressure over the NE U.S., resulting in very little in the way of clouds and likely no measurable rain. High temperatures will average at least 6 to 10 degrees above normal.
To answer the questions: "Is that Relative Humidity reading at Bradford Airport real? Is the sensor broken?" -- It is real. Neighboring sensors (PENN DOT, PA DCNR, and citizen) confirm the dryness of the air.
