Bill Murray: Showers, storms spread over Alabama through Saturday morning; watching the Gulf

COLD FRONT APPROACHING: A cold front is lined up from Chicago to south of St. Louis to west of Little Rock to Texarkana to Waco this afternoon. Showers and storms are quite active ahead of the front, including portions of northwest Alabama, western Tennessee and northern Mississippi.

Storms that have developed out ahead of the cold front are moving through some rather unstable air. We also have lapse rates in the range where we could see some hail develop and fall with these stronger storms. The good news is that we lack the helicity for any of these storms to start rotating. Therefore, any stronger storms will mainly be a gusty wind and small hail threat. At this point, there is not that much lightning being detected with these storms, so they may be on a slight weakening trend at the moment.

The cold front continues to lag behind with the main line of showers and thunderstorms still to the west of the Mississippi River. That will eventually move into the northwestern parts of north and central Alabama around or just before 10 p.m. and progress slowly through the area overnight, not exiting completely until well into the evening Saturday.

The Storm Prediction Center does not have any risk for severe weather up for any part of north and central Alabama for today or on Saturday, but as we have seen today, we could get a storm or two to briefly become strong with gusty winds and some small hail.

THIS EVENING: These storms will slide southeastward during the evening, overnight and into Saturday morning. But now it looks like most of the activity will remain northwest of I-59 through midnight, with a few showers developing elsewhere, mainly southwest of Birmingham around Bibb, Hale and Perry counties.

FRIDAY NIGHT LIGHTS: For the high school games tonight, and for UAB’s tilt at Legion Field with Louisiana at 7 p.m., showers and storms are possible, but I think most stadiums remain dry through the final gun. Take the rain gear just in case, though.

SATURDAY: Showers and storms will become fairly widespread before dawn across parts of central Alabama. By noon this activity should push southeast of I-59, where storms will continue to be possible through the afternoon. A few additional showers will develop during the afternoon. Highs will be in the lower and middle 70s generally. Some sun could poke through during the afternoon.

GRIDIRON FORECAST: Saturday, Auburn will take on Ole Miss in Oxford (11 a.m. kickoff). There will be a mix of sun and clouds with temperatures in the middle and upper 60s during the game.

Alabama is also on the road, taking on Tennessee in Knoxville (2:30 p.m. kickoff). The rain should be over there as well. Temperatures will be in the upper 60s.

SUNDAY/MONDAY: Look for beautiful days both Sunday and Monday with partly cloudy skies and highs around 80. Lows both nights will be in the lower 60s. A few showers could return Monday evening.

EYES ON THE GULF: We are tracking a tropical disturbance over the western Caribbean that continues to get better organized this afternoon with increasing convection. It will likely become a tropical depression later today or tonight and a tropical storm Saturday. It will meander across the western Caribbean and cross into the southeastern Gulf early next week. It will be drawn northward ahead of an approaching trough that will bring more active weather our way at midweek. For now, it appears that a moderate to strong tropical storm could affect the northern Gulf Coast somewhere between southeastern Louisiana and the Big Bend of Florida late Wednesday into Thursday. I am basing our forecast off the notion that the storm will be drawn a little farther west and ride up along the approaching front ahead of the trough at midweek, bringing more rain to Alabama.

TUESDAY: A few showers and storms will be possible, although most of the day will be dry. Highs will again be near 80.

WEDNESDAY: We should see increasing rain and storms with a Tropical Storm Zeta over the Central Gulf. Rainfall could become heavy over central Alabama Wednesday night. Rainfall amounts could exceed 4 inches in many spots based on this forecast. Of course, it would become windy as well with gusts to more than 35 mph late Wednesday into Thursday. Tornadoes could be a possibility as well.

THURSDAY INTO THE WEEKEND: Rain should gradually end over central and north Alabama as the system exits the state. It should set the stage for a nice fall-like weekend with highs in the upper 60s and lows in the upper 40s.

GRAIN OF SALT: Of course, a track further to the east could draw most of the moisture away from central Alabama and we could see some meager rainfall amounts.

GULF COAST IMPACTS: The future track of the potential tropical storm will define weather along the beaches of Alabama and northwest Florida. Tropical-storm-force winds, above-normal tides and very heavy rainfall amounts will occur across a wide area where the storm decides to come ashore during midweek. Highs will be near 80 and lows near 70 until the end of next week. Water temperatures are in the middle 70s.

ELSEWHERE IN THE TROPICS: Hurricane Epsilon has top winds of 85 mph this afternoon as it is beginning to turn northeast, moving away from Bermuda. It will pass well south of the Canadian Maritimes Saturday and Sunday. There also could be a system in the Caribbean the first week of November. It should not pose any threat to the U.S.

NATIONALLY: A big winter storm will affect the northern Rockies Friday and Saturday. Snowfall totals could approach 25 inches in the mountains of west central Montana. Winter Storm Watches and Warnings are in effect.

DANCING WITH THE STATS: Several high-temperature records were set Thursday from the Plains to the Northeast, including 87 degrees at Wichita, Kansas, 90 at Amarillo, Texas, 81 at London, Kentucky, and 82 at Williamsport, Pennsylvania.

ON THIS DATE IN 1920: Famed research meteorologist Theodore Fujita was born in Kitakyushu City, Japan. Fujita, known as “Mr. Tornado” after developing the international standard for measuring tornado severity, also discovered microbursts – sudden, severe downdrafts that can result in 150 mph winds on or near the ground – after studying the starburst patterns of trees uprooted by tornadoes.
