PM Update: Warm and humid with spotty shower chances into Thursday

By this past summer’s standards, this afternoon’s temperatures and humidity levels were a walk in the park. But when you compare these conditions to the dry, crisp air in recent days, it definitely felt muggy. It stays this way into tomorrow, and we throw in the chance of some showers as a cold front edges closer.

Through Tonight: Showers over southern Pennsylvania along a cold front will only slowly sink south and it’s questionable whether any make it into our region by morning. I’ll call for a 30-40% chance (highest odds in the northern suburbs) of showers and maybe a rumble of thunder - best odds late at night. It’s very mild, with lows 60-65 (suburbs-city).

Thursday: The cold front is not going to make a lot of progress south, but it gets close enough to increase shower and thundershower chances to around 40-50 percent (highest odds in northern Maryland). Despite these odds, it’s dry more often than not, with rain favored towards the afternoon and evening. It remains mostly cloudy and warm, with highs in the low 80s.

Intense storm batters United Kingdom: The storm with the lowest pressure measured in the region 30 years swept through Britain Tuesday, the UK Met Office reports. The pressure bottomed out at 973 mb, the lowest since 1981 when pressures sub-970 mb were measured. Flooding rain and strong winds resulted from the unusually deep storm.
