SPC Day 2 Outlook – Issued on January 18, 2019

Basic Info:

  • The SPC has placed Northern Alabama under a Marginal Risk for severe storms
  • Main threats would be Damaging Winds & Isolated Spin-Up Tornadoes
  • Timing is between 9AM (Northwest Alabama) to 3PM (Northeast Alabama)

Detailed Information:

A potent storm system and associated cold front will bring the risk of strong to marginally severe thunderstorms during the day on Saturday.  This will be your classic Low-Instability type event with CAPE Values barely reaching above 400 J/KG. Latest NAM & HRRR Guidance suggests that CAPE will remain relatively low, and there may be a CAP in place. However, since the NWS & SPC remains with a marginal risk, the situation definitely bares watching.

What you can do to prepare:

  • Make sure to have a way to receive any watches & warnings that are issued
    • Have fresh batteries in your NOAA Weather Radio
  • Mobile Battery Packs are recommended in case of power failure to charge cell phones & tablets, etc.

This Hazardous Weather Outlook is for north Alabama and portions of
southern middle Tennessee.

.DAY ONE...This Afternoon and Tonight...

The probability of widespread hazardous weather is low.

Isolated thunderstorms will move into northwest Alabama after
midnight, as more widespread showers move across the area.

.DAYS TWO THROUGH SEVEN...Saturday through Thursday...

Showers and thunderstorms are possible on Saturday ahead of a strong
cold front moving across the area. Gusty winds and locally heavy
rainfall is possible with this activity.

Much colder air sweeping in west of the front could cause rain to
mix with, or become briefly all snow late Saturday night. No
accumulations of snow are expected at this time. Water from recent
rains that does not evaporate before the onset of freezing
temperatures could freeze, resulting in patchy black icing before
daybreak Sunday.


Activation of storm spotters and emergency management personnel is
not anticipated at this time.
