#WDEFWeather #News12Weather #WeatherAlmanac for #ChattanoogaTN on Friday, 9.27.24: Very mild on the daily temperatures.
Friday was the 2nd rainiest day for the date since 1979 according to NWS records. Now a surplus of rain for September.

End of the week brings an end to what was #Helene, but remnants of the storm will affect us through the weekend. Also: how you can become a #Skywarn volunteer #stormspotter without leaving home.

All that and much more in tonight's WDEF News 12 exclusive video #weatherblog #WeatherOvertime.

"NHC forecasts of Helene's landfall were extraordinarily consistent, particularly after the PTC stage (beginning with the 5th forecast in this sequence). At that point, all the forecasts fell within about a 40-nm-wide circle, and nailed the timing within ~2 h. (1/5)"

@FranklinJamesL, Former Chief, Hurricane Specialist Unit, National Hurricane Center, NOAA/NWS (retired).

Via @NWSMorristown, which covers part of the @WDEFNews12 viewing area, 9.28.24 "Open House has been cancelled due to Hurricane Helene. No backup date has been set yet."

1. Western Caribbean:
An area of low pressure could form over the western Caribbean Sea by
the middle of next week.

Environmental conditions are expected to be conducive for slow development thereafter while the system moves generally northwestward, potentially entering the Gulf of Mexico by the end of next week.

* Formation chance through 48 hours...low...near 0 percent.

* Formation chance through 7 days...low...30 percent.

#WDEFWeather #News12Weather #BlipCast Friday: Remnants of #Helene will linger into the weekend affecting our forecast with breezy and sometimes rainy conditions.
