Hope you enjoyed the sunshine and dry conditions today, because it is about to be a very cloudy and wet forecast through at least Tuesday night. A strong storm system will be heading from the Southern Rockies into the Central Plains and Midwest, where Blizzard conditions are expected. Further to South, rain and strong storms will occur, some of the storms are expected to be severe at times, damaging winds will be the greatest threat from this storm system. That part of the system will be heading towards Alabama overnight tonight, and we can expect rain to be getting to West Alabama by early tomorrow afternoon.
Another issue we may see develop across the state, will be a flooding threat. Since January 1st, Birmingham is already nearly two and half inches above normal for rainfall this year. The slow moving system will be dropping heavy rainfall across the Southeast. A look at the latest Quantitative Precipitation Forecast (QPF) from Sunday evening through Tuesday evening shows very heavy rain fall totals are expected during that time frame. This forecast shows the highest totals over southern Mississippi and southwest Alabama where it looks like areas near Hattiesburg could receive over five inches of rain. Across much of north central Alabama, many areas could expect to receive two to four inches of rain. I know the National Weather Service in Huntsville has already issued a flash flood watch that will take effect Sunday afternoon, and I expect that other NWS offices will issue flood advisories before and during this event. Make sure you stay aware of the changing weather conditions the next few days and never drive through flooded roads…TURN AROUND, DON”T DROWN!!!
Friends at my church have a daughter who is currently living in New Haven, CT. They sent me these pictures this afternoon, and I thought I would share them with our Blog viewers. Quite an amazing snow storm!
Additional accumulation this morning at Boston’s Logan Airport put the current blizzard solidly into fifth place in terms of all time snowstorms there.

…the 17 inches at Providence RI ties for 8h all time there.
…35.5 inches at Gorham, ME is the highest total I have seen so far.
…31.9 inches at Portland ME is an all time record snowstorm there.
…the 30.0 inches at Bridgeport CT from a coop observer may well tie the all time 24 hour snowfall record for Connecticut.

It is a great looking afternoon across Alabama and much of the Southeast. If you have the chance, get out and enjoy this weather. Skies are mostly sunny from the Carolinas to about the Mississippi River. To our west in Texas and Oklahoma, we beginning to see an increase in showers and thunderstorms along the dry line in the western parts of those states. Expecting severe weather to develop in that region this afternoon and that system will be heading our way overnight.
By tomorrow morning, the clouds that are in Louisiana and Arkansas will have moved east over Alabama. Expecting to start the day off dry tomorrow, but it will be mostly cloudy and the clouds will be on the increase through the day. Showers and thunderstorms should be impacting Alabama by mid afternoon. Some storms could be severe at times. A very wet start to the week. Don’t expect to see skies this clear again over Alabama until late Wednesday afternoon at the earliest, but it will probably be Thursday before we see full sun again.
The latest Day 2 convective outlook issued by the Storm Prediction Center in Norman, Oklahoma now has much of West Alabama in a slight risk for severe weather tomorrow. This does include many areas along and west of Interstate 65 and includes the cities of Birmingham, Cullman, Tuscaloosa, Jasper, Hamilton, Fayette, Vernon, Aliceville, Clanton, Selma, Demopolis, Livingston, Grove Hill and Mobile.
A slight risk means there is an elevated chance of some organized severe weather in the risk area. However, remember that you do not have to be in a risk to experience severe weather.
For Alabama, it looks as though the worst of the weather will hold off until Sunday afternoon. A warm front will be lifting across Alabama on Sunday, bringing in more moist and unstable air from the Gulf of Mexico. Low pressure in the Plains will track northeast into the Midwest and will be swinging a cold front through the region. The uplift with the front, increase wind shear from the low, and instability from the moist air, will gives us a threat for severe weather.
For major severe weather outbreak across Alabama, it is best for the low pressure to be in Arkansas, or Southern Missouri. This low will be further to the north and west, so we are not expecting a major severe weather outbreak, but the ingredients will be in place for a threat of some strong to severe storms across the Southeast. The main threat from this system will be damaging winds, but some isolated tornadoes will be possible, especially in areas of Louisiana and Mississippi. Still plenty of time to watch this and things can change, but just make sure you have effective ways to receive severe weather notifications.
