BIRMINGHAM, AL (WBRC) -

The FOX6 StormWarn team has been monitoring a weather system that could result in severe weather Friday morning.

Based on current forecast models, the storm line could enter west Alabama around 2 a.m. and arrive at the I-65 corridor around 5 a.m.

The biggest threats with this system could be damaging winds and the team hasn't ruled out the possibility of "quick spin up tornadoes." The line will move into east Alabama later in the morning and more rain could develop after the main line of storms.

Meteorologist Wes Wyatt explains more in his latest weather blog:

In addition to warmer weather, another big headline for our area will be a severe weather threat for early Friday. We're already seeing the threat for severe storms ramping up across parts of the nation. A tornado watch has been in place for Missouri today, with severe thunderstorm watches extending north to Chicago.

Warm & Very Windy Tomorrow

You can expect a mix of clouds and sun for tomorrow, with a gusty south wind. Highs will be in the 80s. I can't rule out a lone shower in West Alabama with the main thunderstorm threat arriving after midnight tomorrow night. A cold front will help trigger a line of rain/storms that will impact our area during the early morning hours on Friday.

What Time Will The Storms Arrive?

We expect a squall line to enter west Alabama around 2 AM on Friday morning. The activity should be closing in on the I-65 corridor, including Cullman, Birmingham, and Alabaster around 5 AM. The bulk wind shear values and higher low level instability (elevated CAPE values) in locations west of I-65 will support possible damaging winds along the line. We're thinking an inversion could prevent lone supercell storms from developing. However, a quick spin-up tornado can never be ruled out within a line of storms. The line should slow and weaken as the main upper support lifts further north. The line will slowly make a push into East Alabama throughout the remainder of the morning, with lower daytime temperatures. Additional post-frontal rain may develop during the afternoon for areas along and east of I-65.

Cooler weather will return this weekend. It will be cold Saturday morning with lows in the 40s. Highs will only be in the 60s, although sunshine will help make for a pleasantly cool afternoon. Lows Saturday night will tumble into the 40s, with highs reaching the low 70s on Sunday.
