Cool Front Friday:
You'll notice falling temps and humidity levels Friday, as cool front delivers a much more comfortable air mass courtesy of Canada.
The front will trigger a few scattered storms as it moves south. There is a (very) slight risk of a severe storm, but overall dynamics are weak.
Tropical trouble brewing: T.S. Lee may dump heavy rain on Gulf Coast.
NHC gives the growing disturbance in the Gulf an 80% chance of becoming Tropical Storm Lee in the next 48 hours.
"A BROAD AREA OF LOW PRESSURE LOCATED A COUPLE HUNDRED MILES SOUTH OF THE LOUISIANA COAST IS PRODUCING A LARGE AREA OF CLOUDINESS...
THUNDERSTORMS...AND GUSTY WINDS OVER THE EASTERN AND CENTRAL GULF
OF MEXICO. UPPER-LEVEL WINDS ARE FORECAST TO BECOME MORE CONDUCIVE
FOR DEVELOPMENT...AND THIS SYSTEM COULD BECOME A TROPICAL
DEPRESSION DURING THE NEXT DAY OR SO. A NOAA HURRICANE HUNTER
AIRCRAFT IS SCHEDULED TO INVESTIGATE THE AREA LATER THIS AFTERNOON. THIS SYSTEM HAS A HIGH CHANCE...80 PERCENT...OF BECOMING A TROPICAL CYCLONE DURING THE NEXT 48 HOURS AS IT MOVES SLOWLY NORTHWESTWARD. INTERESTS ALONG THE ENTIRE NORTHERN GULF OF MEXICO COAST SHOULD MONITOR THE PROGRESS OF THIS DISTURBANCE."
Forecast models are moving "Lee" slowly toward the north.
The slow movement means the central Gulf Coast will likely get hammered with torrential rainfall over the next few days. Southern Louisiana, including New Orleans, and Mississippi could pick up 10" to 20" rain totals.
Meanwhile Katia continues to churn westward in the Atlantic. The latest trends in steering currents keep Katia moving more west than north. NHC has adjusted the forecast track westward to reflect the left leaning trend in guidance.
That will bring Katia dangerously close to the Carolina coast late next week. Most of the models stil insist on then recurving Katia and accelerating the storm to the north, east of the U.S. mainland.
But if the track stays any farther west Katia could become a threat to the eastern USA.
Stay tuned!
