Alagasco Seven Day Forecast
Friday afternoon, December 19, 2014
Forecaster: Ryan Stinnett
RAIN MOVING IN: A developing low pressure along the Texas Coast will be the major player in our weather the next 24 hours. The low is pumping north ample moisture from the Gulf and that moisture is falling across the state in the form of rain. A large mass of rain over Louisiana and Texas is spreading towards Alabama. The rest of today, clouds will only thicken, temps will hang in the 40s and 50s, and rain will begin to fall during the evening hours.
RADAR CHECK: All day long, the rain has been spreading slowly northeast from the Gulf. At just before 2PM this afternoon, the rain had made it into Southwest Alabama. With some areas of light to moderate rain down towards the 80 corridor. The vast majority of the rain remains back in Mississippi, but don’t worry, it is on its way to Central Alabama. For Central Alabama, rainfall totals should be up to one half inch, with heavier totals down south.
WORLD TEMPERATURE EXTREMES: Over the last 24 hours, the highest temperature recorded was 111.9F at Nullagine, Australia. The lowest temperature was -62.0F at Ust-Nera, Russia.
CONTIGUOUS TEMPERATURE EXTREMES: Thursday afternoon it was 80F at Fort Lauderdale, Florida and Brownsville, Texas. This morning, it was -6F at Raco, Michigan.
WEATHER ON THIS DATE IN 1777: The Continental Army moved into encampment at Valley Forge amidst stormy winds and piercing cold. A relatively moderate winter followed.
THE ALABAMA WEEKEND: Saturday will start off wet for most of us, but heading through the day we should see the rain taper off from west to east across the state state. There may even be a few peeks of sunshine by the afternoon. Highs on Saturday will be in the mid-50s. For Sunday, the sky will be occasionally cloudy with a high in the upper 50s. The same area of low pressure will be stalled over the northeastern Gulf and will bring the risk of some light rain back in here by Sunday night; best chance of rain will be south of I-20, and east of I-65.
MONDAY: We will likely start the day off with a few showers, especially over southeastern portions of the state. By midday and into the afternoon, most locations should be dry, but expect mostly cloudy conditions with highs in the upper 50s.
TUESDAY: A cold front approaches the region and we will have to mention a chance of showers and storms Tuesday afternoon and Tuesday night. A few storms could be strong Tuesday evening, but this is not a classic severe weather setup, but always something to watch this time of the year.
CHRISTMAS EVE: The rain will move out very early Wednesday morning, and the day Wednesday will be breezy and colder with lingering clouds; a decent chance we won’t get out of the 40s. The sky will clear late in the day.
CHRISTMAS DAY: Still looks to be the best day of weather out of the next seven as we are forecasting a good supply of sunshine. It will be a cold start to the day with most locations below freezing as upper 20s and low 30s are expected. By the afternoon, the temps will rise into the mid-to-upper 50s.
END OF WEEK SYSTEM: Friday looks to be very nice with more sun than clouds and temps into the 60s. However, it still looks as though another rain maker approaches the Southeast by the first part of the weekend. Clouds should be increasing by late Friday and it appears we can expect rain to move in late Friday night and into Saturday.
VOODOOLAND: Model data continues to show a colder pattern for the Deep South as we approach the beginning of the new year. The models are showing the zonal flow being replaced with northwesterly flow. This could allow the opening of those cold air flood gates from the Arctic, which will allow very cold air into the U.S. Of course, stay tuned…
