Area Forecast Discussion National Weather Service State College PA 357 PM EDT Tue Jul 2 2019 .SYNOPSIS... A large upper level ridge will keep the region warm and humid for the rest of the week. Expect a chance of thunderstorms each afternoon and evening right on into the weekend. && .NEAR TERM /UNTIL 6 AM WEDNESDAY MORNING/... Most humid air of the summer quickly moved into the CWA this morning with many locations reporting dew points over 70. HRRR model not even close showing dew points in the lower 60s. Showers and some thunderstorms developing on schedule this afternoon. Despite poor low level moisture fields on HRRR, it's still showing active convection for the rest of the afternoon and early evening. Forecast has this covered. Cells are moving rather fast, to the southeast at 20-30 mph. This fast cell movement should limit rainfall totals. Once convection diminishes after sunset look for a warm and muggy night with patchy fog development towards sunrise. && .SHORT TERM /6 AM WEDNESDAY MORNING THROUGH 6 PM WEDNESDAY/... Another warm and humid summer day with afternoon thunderstorms developing across the region. SPC continues to have the area under a marginal risk for severe thunderstorms. && .LONG TERM /WEDNESDAY NIGHT THROUGH TUESDAY/... 1. Repeat summertime pattern with very warm and humid conditions fueling rounds of thunderstorms through Saturday. The strongest storms may produce strong to locally damaging wind gusts, hail, and heavy downpours. Stay alert and be prepared for disruptions to outdoor activities through the first part of the 4th of July weekend. 2. Max heat index values are forecast to peak around 95-99F in the lower Susquehanna Valley later this week and remain just below heat advisory criteria. Practice heat safety. 3. Slightly cooler and less humid airmass likely to arrive Sunday with drier trend into early next week. && .AVIATION /20Z TUESDAY THROUGH SUNDAY/... VFR outside of any showers and thunderstorms which will develop this afternoon. Cell movement will be southeast at 15 to 25 knots. Expect patchy fog late tonight, mainly across the north, and in areas that get rain. .Outlook... Wed-Sat...Scattered PM thunderstorms possible, with localized restrictions. && .CTP WATCHES/WARNINGS/ADVISORIES...
