Severe Storms Continue For Tuesday

5pm climate report for Tuesday
5pm climate report for Tuesday
Scott Derek

Monday was deja vu all over again! We once again had some morning showers just like Sunday and then the clouds broke by late morning; there were some isolated showers and thunderstorms to the east across New Jersey during the early afternoon, but everyone saw severe thunderstorms by the evening commute. As of the 5pm climate report Philadelphia International Airport reached 90 after a morning low of 74; there was also a trace of rain reported, but that number shall be updated with the final climate report issued overnight.

A frontal boundary responsible for the severe thunderstorms continues to push northeast while a more potent cold front pushes through Tuesday night

Speaking of overnight it will remain cloudy with scattered showers and thunderstorms(below severe criteria) as lows will just be in the lower 70s; Tuesday's another day with more clouds than sunshine and then another round of showers and strong to severe thunderstorms in the afternoon. There will be the upper-level(500-millibar, or 18,000 feet) low swinging on through and this will do is create a lot of instability aloft and with the continued "juicy" airmass on top of the region it just takes the rising of air parcels to pop up a storm; there will also be strong wind shear aloft (wind direction and/or speed changing with height) that can cause gusty winds, large hail, and also the threat of a few spinups(funnel clouds and tornadoes) just like Monday. Highs will be in the upper 80s.

The showers and thunderstorms will finally come to an end in the early morning hours on Wednesday and by the afternoon we'll get drier air as highs will be in the lower 80s with increased sunshine. After a comfortable night in the lower 60s we'll only be in the upper 70s on Thursday thanks to a northerly wind as the core of high pressure is on top of the region. That's almost TEN degrees BELOW average! It will feel more like Mid-September than Mid-July! You will be able to give your air conditioner a rest for the day and just simply open up the windows! On Friday we'll be in the lower 80s with continued low humidity, but then for the weekend an area of low pressure will slide up the Appalachians and the humidity will creep up as well. Saturday will feature increasing clouds with highs in the lower 80s and an easterly(onshore) wind, but I feel that the showers would hold off until after dinnertime and last through the overnight. Sunday will feature scattered showers and thunderstorms with highs in the middle to upper 80s as the low pressure finally pushes to the east. We'll have sunshine return for Monday with highs in the seasonable upper 80s, but it will remain humid.
