(1/4) Alright, snow fans! The moment you've all been waiting for has arrived: my 2026-2027 Winter Outlook! Two primary winter-season influences will be our Super, east-based El Niño and slightly-negative Pacific Decadal Oscillation (PDO)..

Winter weather forecasting is complex. As we make forecasts throughout the winter, we pay especially close attention to the “warm layer” aloft. It determines whether you’ll see snow, sleet, freezing rain, or rain at your location! #WinterPrepPA #PAwx
In today's SWD, I highlight the unseasonably warm weather through the end of the week, beneficial rain later tonight into tomorrow, and cooldown over the weekend. Despite more seasonable conditions next week, no "cold days" are in the foreseeable future.

Behind tomorrow morning's disturbance, SW flow will continue to pump warm and humid air into the LSV. Clouds may break for some PM sun, and high temps should soar into the low-to-mid 70s again with dewpoints in the low-to-mid 60s. A few additional showers may erupt after midday.
A weakening disturbance will sweep through the mid-Atlantic States from SW-to-NE spanning tonight into tomorrow and bring showers or a period of light rain to northern MD, southeastern PA and the LSV between ~1-11 AM Thursday. Rainfall amounts should not exceed 0.50-0.75".

When a snow squall hits, visibility can drop to almost nothing in an instant. There is no safe place on a highway during a snow squall, but if you do get stuck on the road: reduce your speed, turn on your headlights, and don’t slam on your brakes! #WinterPrepPA #PAwx
Southerly winds of 8-16 mph on the backside of a high pressure system over the western Atlantic will continue to pump unseasonably warm air into northern MD, southeastern PA and the LSV today. Under mostly sunny skies, high temps will soar into the mid- to perhaps upper 70s!
In today's short-term video, student meteorologists Charlie Beetham, @mitchell_cokain and @roonski03 highlight the unseasonably warm conditions through the end of the week, as well as the return of wet weather on Thursday.

To complement yesterday's discussion, I posted my 2026-2027 Winter Outlook video. It's lengthy, but one that should interest snow lovers & heat misers alike! I also give a month-by-month breakdown of expected temp/precip departures. #winteriscoming #ElNino

Snow, sleet, and freezing rain! Lots of winter vocabulary will be used in the next few months! Learn more about winter precipitation from the @NOAA National Severe Storms Laboratory: nssl.noaa.gov/education/svrw… We’ll talk more about snow & ice in the next two days #WinterPrepPA #PAwx
Light, southerly flow on the backside of a high pressure system over the western Atlantic will pump even warmer air into northern MD, southeastern PA and the LSV today. Under mostly sunny skies, high temps will be 10-15°F above normal, or in the low 70s. #GetOutside and #Enjoy!

I highlight 4 primary factors in the seasonal forecast and outline how they should influence temp/precip patterns across the region. Let's see how I do! #StayTuned
(3/4) Overall, it will be a "backend winter" with an enhanced risk of a major Nor'easter or two between Jan 20-Feb 20. However, aggregate temps. should be above normal (3-5°F) with snowfall perhaps near normal (20-30"). The coldest periods will likely occur in late Jan or Feb..

Do you know the difference between a watch, advisory, and warning? Be prepared, exercise caution, and take action! You can check the current weather for your area anytime at weather.gov/ctp. #WinterPrepPA #PAwx
Light, southerly winds of 6-12 mph on the backside of a high pressure system over the western Atlantic will usher warmer air into northern MD, southeastern PA & the LSV today. The thick veil of cirrus clouds will gradually thin out, & high temps should reach the mid-to-upper 60s.
Due primarily to a complete absence of "cool shots," #October2026 concluded as the 12th-warmest on record at @millersvilleu since 1914. Rainfall was "near normal" at 2.81". However, most of that fell in one day thanks to the remnants of #Isaias.

Did you know that October 2026 was one of the LEAST WINDY Octobers on record in Central PA? 🌬️
With high pressure nearby for most of the month, there was little to no wind most days! 😎
A wet summer followed by a dry, warm, & calm October made for IDEAL fall colors! 🍂

It's time for your Week 5 Fall Foliage Report! 🍁🍂
The continued pattern of warm days followed by cold nights and frosty mornings is continuing to transform southern Pennsylvania’s forests into a mosaic of fall color.
