Record-challenging warmth again today with strong, heavy t-storms possible

Much cooler with snow or flurries to end the week

TODAY: Breezy at times and warm with showers and in parts of the area a strong thunderstorm. High: 71

TONIGHT: Windy and chillier with a shower around early. Low: 46

THURSDAY: Blustery and chillier despite some sunshine (flurries around). High: 48 Low: 27


With a mild start to the day, temperatures could spike into the low 70s this afternoon ahead of an advancing cold front. As a result, the record high will be broken in Allentown and challenged in Reading. The record for Allentown is 67 and the record for Reading is 76; both were set back in 1972.

We've seen rain and showers this morning with some embedded thunderstorm activity. After a break from the action, the activity is expected to pick back up this afternoon with the potential for strong and heavy storms. The Storm Prediction Center has most of the viewing area in a "slight risk"  category for severe weather and an "enhanced risk" south and west of Reading, which means flooding downpours, strong winds, hail and even an isolated tornado are possible with these storms. The biggest threat will be the potential for damaging wind gusts in excess of 50 mph. Rainfall totals from this event will generally be between .25" and .75" with locally higher amounts likely.

The winds will pick up in the wake of the cold front tonight and usher in colder air and a flurry or snow shower on Thursday. Those flurries and snow showers on Thursday will mainly stay north and west of the Lehigh Valley. Otherwise, Thursday will be cooler but still above average as temperatures top out in the upper 40s with some sunshine. The winds at times on Thursday will make it feel like it's in the 30s.

A little Alberta clipper will slide through the region into Friday. While we're expecting less than .10" of precipitation with this clipper, the precipitation will fall as snow and slick spots are possible. The snow showers and flurries should primarily end by the afternoon. As that clipper exits to the east, any snow will taper off and the clouds will break for some sunshine. High temperatures on Friday will be close to 40 degrees.

Temperatures will still be chilly on Saturday in the upper 30s before bouncing back to average on Sunday in the mid 40s. Saturday appears to be a dry day with plenty of sunshine, but the clouds will build on Sunday with a shower possible in the afternoon.
