Showers continue in Philadelphia area Thursday and Friday morning as temps drop. Here's the forecast.

A storm system moving through the Philadelphia region is bringing several rounds of wet weather today and into Friday, with the greatest potential for thunderstorms from midmorning through the early afternoon. A tornado watch is in effect in Burlington County until 7 p.m. Thursday, with the primary threats including a few tornadoes, damaging wind gusts up to 70 mph and large hail. The tornado watch for the rest of the region has ended. Flash flood warnings are in effect in much of the region Thursday evening. Tornado warnings in Burlington, Mercer and Monmouth counties in New Jersey have expired. Showers and embedded storms became more widespread in the afternoon hours, with locally heavy downpours, gusty winds and reduced visibility creating potentially difficult travel conditions. While widespread severe weather is unlikely, we are in a slight (level 2) severe risk and a 5% tornado risk due to the warm front moving through and the wind shear accompanying today's storms — a brief spin-up tornado can't be ruled out. The unsettled weather won't be finished, with additional showers expected tonight, followed by another round of steadier rain Friday morning. Colder air arriving behind the system will send temperatures tumbling from near 60 degrees today into the 40s Friday, with a brisk breeze making it feel even chillier. In the Poconos, some slushy accumulation is possible Friday morning, with flakes mixing with rain even into the Lehigh Valley. Rain should gradually taper Friday afternoon, setting the stage for a mainly dry but cool weekend. THURSDAY: Mostly cloudy with rounds of showers and thunderstorms, especially late morning through early afternoon. A few storms could bring gusty winds and heavy rain before activity becomes more scattered later in the day. Mild, with highs in the upper 50s to lower 60s. THURSDAY NIGHT: Mostly cloudy with additional periods of rain, especially later. Turning cooler with lows in the lower to mid-40s. FRIDAY: A chilly, breezy and unsettled day with periods of rain during the morning and a few lingering showers possible in the afternoon. Temperatures will struggle to climb, with highs mainly in the lower to mid-40s. A significant change from Thursday's milder weather. PLANNING: The weekend looks considerably quieter, although clouds will be stubborn on Saturday with a brisk breeze and highs in the upper 40s. Sunday brings some morning sunshine before clouds increase, with temperatures recovering into the lower 50s. The dry weather continues into early next week, with partly sunny skies Monday and Tuesday and highs gradually climbing through the 50s. NEXT BIG CHANGE: After Thursday's stormy weather and Friday's chilly rain, a stretch of drier and more seasonable weather takes hold this weekend and continues through much of next week. Sunshine becomes more plentiful by midweek, with temperatures gradually rebounding into the mid- to-upper 50s.
