The 2021 Fall Foliage Season and Fall in general has gotten off to a painfully slow start for fall-lovers like myself. Friday will feature temperatures in the 80s for many of us, and once again the thought of turning off the AC will not cross your mind. But there is good news. Next week will…
Warmer than normal temperatures delayed the onset of fall foliage season about a week, but some of us are beginning to see changing foliage. Change has been most significant around and north of I-80, especially in the higher elevations near the NY border. Meanwhile in the lower elevations across the Susquehanna and Lehigh Valleys, little…
After a hot summer, temperatures have cooled somewhat slower than normal with the onset of Fall. Above average temperatures are expected for much of October, meaning fall foliage season will be a little behind schedule, but that does not mean we won’t see vibrant colors here in Pennsylvania. Recent heavy rain that has occurred in…
Wednesday has become the official day of bad weather over the past month, and this Wednesday will be no exception. A closed-off low pressure system will very slowly move northeast in the coming days, dragging a front through the area ever so slowly. This unfortunately means some cloudy, rainy days are on tap, but at…
Here comes another Wednesday with bad weather possible across much of the commonwealth. Scattered strong to severe thunderstorms are expected to develop mid-day Wednesday over Western and Central Pennsylvania and move east from there. Weak shear in our area will lower the tornado risk, but damaging winds and hail remain possible. This is all relatively…
It has been a tranquil stretch of weather since the remnants of Hurricane Ida swept through last Wednesday. The upcoming week or two looks pleasant as well, but not before a cold front accompanied by strong to severe thunderstorms marches into the area Wednesday. We are well past the peak of severe season, so this…
Scattered heavy rain has already begun in parts of the state as this 24-36 hour deluge is just about to get going. Moderate to major flooding is now projected for many creeks in southern PA, and we will be monitoring the larger rivers for rises into minor flood stage. In addition, many of the usual…
OUR FINAL CALL FORECAST HAS BEEN POSTED: As Ida moves closer to the region, our confidence that widespread flooding will occur continues to increase. The state has not seen this kind of event since Tropical Storm Lee in 2011, and while it’s unlikely Ida will bring similar impacts as Lee, significant impacts are still expected.…
SECOND CALL RAINFALL FORECAST POSTED: Hurricane Ida will be the third tropical system to impact Pennsylvania this hurricane season and it’s still just August. Hurricane Ida made landfall in Southeast Louisiana Sunday afternoon as a strong category four storm with winds of 150 MPH. Ida will slowly make its way our direction, but will not…
A Category 4 Major Hurricane Ida is expected to make landfall Sunday afternoon in Southern Louisiana, where mandatory evacuations are ongoing. Winds at landfall are modeled to be around 140mph, with higher gusts possible. Conditions in the central Gulf of Mexico will be very favorable for rapid intensification. Here is the latest forecast from the…
Tropical Depression Fred is already producing heavy rain across the southern Appalachians as well as an enhanced tornado risk in the Carolinas, and all those impacts will quickly be making their way up into our region by Wednesday. Moderate to heavy rain will persist through much of Wednesday across the Alleghanies and Appalachians, and a…
Summer is not easing off the breaks whatsoever this week, with excessive heat combined with a severe thunderstorm risk nearly everyday in much of the state. Heat indexes will top out between 100-110F in much of the eastern half of the state lowlands, and 90-100F in the highlands. Below are the expected heat indexes Thursday…
An area of heavy rain potentially with embedded thunderstorms will move through western and central PA Thursday morning and early afternoon. This may work to limit convection and instability, which would reduce the severe threat. A few hours of clearing is almost always required to destabilize the atmosphere, and where the destabilization occurs in the…
Thunderstorms are expected to pop-up early this afternoon over the northern PA mountains and push southeast in the mid to late afternoon. At the same time, the wildfire smoke will also be pushing southeast, as illustrated in the map at the bottom of the post. The Philadelphia Area has the greatest risk of scattered severe…
July has gotten off to an incredible start in parts of Pennsylvania rainfall-wise, with northeast Philadelphia suburbs already over a foot of rain in two weeks. Many other areas have seen 3-7″ of rain. Nearly the entire state is well above average so far this July with the exception of south of Route 30. Check…
