Well, this morning was a rude spring awakening. Fresh from a record-tying 77 degrees on Friday the weather has descended into a rain-snow mix. That mix will lean more toward the snow portion in the northern parts of the city, while the warmer southern half should stay mostly rain. The precipitation is from a warm front that is trying to pass through the city. The front is temporarily stuck but it should move northward this afternoon. Today's highs will be near 50 for most of the city but the temperature will remain in the 30s just north of the city.
The warm front is so slow because the surface storm has little upper-level support. On its own warm, moist air has a heck of a time displacing the colder, drier, and thereby denser, air that's just to the northeast of the city. A superhero cold front will dispatch both systems when it swoops through town tonight. Tomorrow's high will be in the sunny and breezy mid 50s.
Don't get too excited that warm weather is here to stay. A messy storm moving out of the Ohio Valley promises to bring a wintry mix of rain and snow from Tuesday night through Thursday. In addition the jet stream is going to shift from an west-to-east pattern to more of a north-to-south pattern. Both those changes mean cooler than normal weather is expected through next weekend and beyond.
