Temperatures will drop quick tonight with a mostly clear sky through the first half of the night. Increasing clouds after midnight will stop the temperature free fall, but look for many spots to be in the 30s for the Wednesday morning commute. With another fast moving disturbance moving through the region, you'll want to grab the umbrella leaving the house tomorrow morning with spotty showers expected by the afternoon. Look for lots of clouds, a stiff west breeze and high temperatures not much above 50. Cold air rushing in behind this system will set us up for the coldest morning of the season thus far with temperatures going down into the upper 20s to lower 30s by Thursday morning. Widespread frost is expected so if you have sensitive plants you'll need to bring them in or cover them up before going to bed tomorrow evening. Thursday will feature partial sun, a decent breeze and highs only in the mid/upper 40s. After another frosty start Friday temperatures will rebound into the mid to upper 50s during the afternoon with a good deal of sun expected.
