BIRMINGHAM, AL (WBRC) - FIRST ALERT FOR FROST TOMORROW NIGHT: The heater will be kicking on tonight as a much colder air mass settles into the state. Currently a cold front is moving south across our area, with showers tapering off across our southern counties. The sky will gradually clear this evening, with lows tumbling into the 30s north, with low 40s further south. We will have a cold north wind overnight and this should prevent frost development tomorrow morning. Sunshine will return tomorrow and plan for a chilly day, with highs in the low 60s. After the sun sets tomorrow night the winds will settle and with a clear sky, radiational cooling will allow for frost development across our northern counties. This first frost of the season will be most likely across the Tennessee Valley as lows tumble into the mid 30s. Most of our area will wake-up to upper 30s Monday morning, especially in outlying areas, so break out the the jacket!
ORIONID METEOR SHOWER: The clear sky tomorrow night will make for great viewing conditions for the Orionid Meteor Shower. The annual event peaks late tomorrow night and into the early morning hours on Monday. The moon will be rather bright, in a waxing gibbous phase, with 91 percent brightness. So this may make it a bit more difficult to see the faint meteors, however, grab a blanket, bundle up, look to the sky, and you may catch over 10 meteors per hour. The moon sets at 4:47 a.m. on Monday so the best viewing conditions will happen just before sunrise Monday morning.
WHAT TO EXPECT NEXT WEEK: After a cold start to the work-week, sunshine will return for Monday, with highs in the upper 60s. A disturbance tracking east along the Gulf Coast will spread lots of clouds north and this will limit the cooling for Monday night. I still expect chilly 40s to start the day on Tuesday. The clouds may linger through a good part of the day on Tuesday, especially for areas to the south. Highs will range from upper 60s to low 70s. We may even see a few isolated showers reach our far southern counties, although most areas should remain dry. Wednesday will be a dry day but I want to give you a First Alert for showers and clouds on Thursday as another storm system passes to our south. This system will pass to our southeast on Friday and this will set the stage for clearing and more chilly fall weather for next weekend. As for tropical weather, things are much calmer, with no concern for development within the next five days. I will be posting updates on our WBRC First Alert Weather App and I will have more specifics on the temperature and precipitation changes in my forecast after the game tonight on WBRC.
