PHILADELPHIA (CBS) — *A Flood Warning is in effect until 2:45 this afternoon for the East Branch of the Brandywine Creek in Chester County*

After a messy week of weather, we have one more day to get through before dry conditions return. Early morning fog and showers on Friday the 13th will eventually give way to some sunshine in the early afternoon hours on Friday. However, we expect thunderstorms to begin popping up then, some which could of the severe variety. That means heavy rain, gusty winds, dangerous lightning, and small hail are all possible. Highs will top out in the low 80s. If you have outdoor plans, you will need to keep an eye to the sky this afternoon.

The cold front that will be bringing these storms will swing through this evening and move out later tonight. And that means … the third straight weekend of excellent weather! We are expecting abundant sunshine both Saturday and Sunday, with high temperatures once again in the low 80s. The humidity and dew points will be refreshingly low after a muggy week.

If you work during the week, this is indeed a very favorable pattern that we are in!

The weekend beach forecast is superb; upper 70s and lots of sunshine. Don’t let the comfortable temperatures fool you though, as UV indices will be high.

Today is Friday the 13th, but we also had a full moon occur early this morning (12:11 a.m. EDT). This is a rare event, but exactly how rare? To start, this is the first time since Oct. 13, 2000, that a full moon has occurred on a Friday the 13th of any month. The last time this happened in June? 1919. The next time we will have a full moon on Friday the 13th will happen on Aug. 13, 2049. So I guess you could say that makes this a pretty lucky day!

Today In Weather History:
1900 — A thunderstorm moved through Stroudsburg, PA. Observers say that it rained on one side of Main Street and not the other.
1958 — F2 tornadoes touched down during late afternoon in the counties of Burlington and Mercer in NJ. An F1 hit Ocean Co, NJ. Thankfully, no deaths or injuries were reported.
