Good evening to everyone!
Please be aware, even though I do not post every night, rest assured I am continuously monitoring various areas for any significant weather.  I will be taking Sundays off (family time), unless we have active systems that may be posing a threat (i.e. Tropical, Winter Weather, Coastal Storms, etc.).

Given the lateness of the evening, I must make this short.  The entire SPC DAY 2 Severe Outlook will be linked to the very first SPC graphic, so you may view it in its entirety.  I have analyzed it myself, but do not have the time this evening to type it out in layperson terms.  I didn’t want to leave you in the dark, and wanted to post something for a heads up.

The SPC has issued a SLIGHT RISK OF SEVERE THUNDERSTORMS OVER PORTIONS OF EASTERN OKLAHOMA AND FAR NORTHEAST TEXAS INTO THE MIDDLE MISSISSIPPI AND LOWER OHIO VALLEYS in the current DAY 2 Outlook…

…SPC SUMMARY…
Severe thunderstorms are expected across parts of Oklahoma and far northeast Texas into the middle Mississippi and lower Ohio Valleys on Monday. Damaging gusts, large hail and a few tornadoes will be possible with this activity. Additional strong to isolated severe thunderstorms are possible from the southern Plains into portions of the Southeast and Mid-Atlantic.

HAIL OUTLOOK
LOWER OHIO valley

Probability of one inch diameter hail or larger within 25 miles of a point.
Hatched Area: 10% or greater probability of two inch diameter hail or larger within 25 miles of a point.

WIND OUTLOOK
U.S. Coast Guard
Probability of damaging thunderstorm winds or wind gusts of 50 knots or higher within 25 miles of a point.

Hatched Area: 10% or greater probability of wind gusts 65 knots or greater within 25 miles of a point

Based on my analysis  of the outlook, regarding some severe weather indices (MLCAPE, STEEP MID LEVEL LAPSE RATES, DEW-POINTS OF 60 – 70F), the atmosphere is forecast to become moderately to strongly de-stabilized.  Based on my analysis this evening of the NAM – WRF model through F5 DATA software, SWEAT values, Lifted Indices, Energy Helicity Index, VGP, and Significant Tornado Parameter are currently forecast to be moderate to high as well.  Based on both the SPC outlook and NAM – WRF information, the following outlined maps indicate where the highest probability currently lies for the strongest of the severe weather, and tornado activity.  Based on analyzed indices, I cannot rule out an isolated EF2 tornado within the risk area, and possible upgrade to an ENHANCED risk over a portion of the SLIGHT risk area by SPC tomorrow in the DAY 1 Outlook.  As a reminder, these areas could change given any risk upgrade from the SPC, and any new information from the next 2 model runs.  Please refer to the SPC home page link below the convective watches graphic for the DAY 1 outlook for tomorrow.

About palmharborforecastcenter

I am a Tropical Forecast meteorologist, providing hurricane forecasts during the Atlantic Hurricane Season. I retired from the U.S. Coast Guard in July of 2001. Meteorology became my passion in high school, and I have continued my educational background in meteorology since 1996, when I undertook the study of Tropical Meteorology. While working toward my degree, I had to unexpectedly withdraw from college due to my oldest sons medical reasons. I do however, meet the educational criteria of the AMS to be recognized as a meteorologist. Studies include, but are not limited to the Navy Aerographers Mate course, Naval METOC meteorology course, Meteorology 2010 Sophomore level course while attending St. Petersburg College, Clearwater, FL., Basic Forecasting course for operational meteorologists from Rapid WX, meteorology institute, a four month meteorological internship, and extensive research on numerous meteorological topics such as the MJO, NAO, satellite imagery interpretation, etc.

I have been forecasting Tropical Weather (Tropical Storms and Hurricanes) since 1996, with my main client being three different Coast Guard Commands.
