Weekly Update 04/04/2009
 

The past week's weather highlight was severe weather outbreak on Thursday (In my opinion, at least). I'll go into more detail later on, meanwhile next week's local weather:

Local Weather

For tomorrow, we will have highs in the mid to high 80s around the area, with a chance for scattered showers in some spots, then on Monday, another chance of rain with highs in the 70s. Tuesday, temperatures take a step back in time (or forward, whichever you prefer) and get unusually cool for this time of year, down into the low to mid 60s.

 Wednesday, a slight warm-up into the high 60s, and then for Thursday, we might see some 70s, and then finally warming up by the end of the week.

Lows will be anywhere from the mid 60s to low 40s / high 30s***

 

***NOOOOOOOOOOOOOOOOOOOOOO! NOT AGAIN!!!!!!

Highlights

The severe weather on Thursday was more than a wind-hail event, as there were 19 tornadoes throughout the day and night. On top of the tornadoes, 142 wind reports and 75 hail reports were sent in to local Weather Forecast Offices.

Overall, there were 200 reports of severe weather Thursday, and unfortunately, severe weather season is just starting. Below are a few links to storm summaries and reports of the outbreak.

I'm going to be changing the look and layout of some of the pages NEXT WEEK. The severe weather page and the local weather page will definitely be changed. I might even do the state pages. I would appreciate it if you would rate on a scale of 1-10 -- 1 being the worst, 10 being the best -- the following things:

1. Current Design
2. Ease of Use / Accessibility to Data
3.Ways To Improve The Site


If you have any ideas or anything you would like added to the site, be sure to include them.

I try to make sure everything is up to date, so if you see anything not updating, or not working right, let me know and I'll fix it ASAP.

Hernando and Pasco County residents can to the local weather page for more info. All residents in the affected counties should stay tuned to their local NWS office and local media for more information.

 
 

The risk of Severe Weather today into tonight is slowly rising as the day progresses. There are tornado watches in Louisiana, Mississippi, Alabama, Georgia, and Florida. Hail and damaging winds are expected, and strong, long-lived tornadoes are a possibility.

 

 Here is the SPC's Convective Outlook for today:

...THERE IS A MDT RISK OF SVR TSTMS THIS AFTERNOON INTO EARLY
   TONIGHT FOR CENTRAL/NRN MS AND AL...
  
   ...THERE IS A MDT RISK OF SVR TSTMS THROUGH EARLY TONIGHT FOR N FL
   AND S GA...
  
   ...THERE IS A SLGT RISK OF SVR TSTMS SURROUNDING THE MDT RISK
   AREAS...FOR THE LOWER MS/OH VALLEYS INTO THE SE ATLANTIC COASTAL
   PLAIN...
  
   ...SYNOPSIS...
   COMPLICATED SCENARIO TODAY WITH THE LARGE ONGOING MCS ACROSS THE NE
   GULF COAST...AND PRE-FRONTAL CONVECTION SURGING EWD FROM LA/AR
   TOWARD MS AS OF MID-LATE MORNING.  THESE CONVECTIVE SYSTEMS WILL
   HAVE A POTENTIALLY LARGE IMPACT ON THE SEVERE WEATHER THREAT TODAY
   INTO AT LEAST EARLY TONIGHT. 
  
   ...MCS FROM NE GULF COAST TO S GA THROUGH EARLY TONIGHT...
   THE TRAINING CONVECTION WITHIN THE GULF COAST MCS WILL LIKELY
   PERSIST THROUGH THE AFTERNOON WHILE SPREADING ENEWD ACROSS N FL/S
   GA/SRN SC.  THIS CONVECTION WILL BE SUSTAINED BY A CONTINUED INFLUX
   OF 68-70 F BOUNDARY LAYER DEWPOINTS FROM THE NE GULF OF MEXICO...AND
   IN THE ZONE OF LOW-LEVEL WAA AND UPPER DIVERGENCE ASSOCIATED WITH A
   SPEED MAX EMBEDDED WITHIN THE SUBTROPICAL JET.  A GRADUAL INCREASE
   IN THE MAGNITUDE OF THE LLJ AND RESULTANT LOW-LEVEL SHEAR WILL
   RESULT IN AN INCREASE IN THE THREAT FOR EMBEDDED SUPERCELLS WITH
   TORNADOES IN THE LARGER CONVECTIVE SYSTEM THIS AFTERNOON INTO EARLY
   TONIGHT.
  
   ...PRE-FRONTAL CONVECTION TODAY ACROSS LA/MS/AL/TN...
   THE PRE-FRONTAL CONVECTION CROSSING THE MS RIVER /WITH AN
   ACCOMPANYING COLD POOL AND POSSIBLE GRAVITY WAVE/ WILL LIKELY SWEEP
   EWD ACROSS MUCH OF MS BY EARLY AFTERNOON AND INTO AL.  15Z SOUNDINGS
   FROM JAN/LIX HAVE SHOWN SOME LOW-LEVEL DRYING SINCE 12Z...BUT STEEP
   MID LEVEL LAPSE RATES WILL STILL SUPPORT MODERATE-STRONG INSTABILITY
   /MLCAPE OF 1500-2000 J/KG/ WITH DAYTIME HEATING.  VERTICAL SHEAR
   WILL BE SUFFICIENT
FOR SUPERCELLS WITHIN THE PRE-FRONTAL CONVECTIVE
   BAND...WHILE LOW-LEVEL SHEAR/MOISTURE APPEAR TO BE LARGE ENOUGH TO
   SUPPORT A FEW TORNADOES.  FARTHER E...THE DISTRIBUTION OF LOW-LEVEL
   MOISTURE/SURFACE HEATING AND RESULTANT INSTABILITY IS IN QUESTION
   ACROSS AL GIVEN THE RELATIVELY EARLY ARRIVAL OF THE PRE-FRONTAL
   LINE...AND THE ONGOING CONVECTION WITH RAIN-COOLED AIR ACROSS SE AL.
    STILL...THE PRESENCE OF BOUNDARY LAYER DEWPOINTS IN THE 60S AND AT
   LEAST WEAK INSTABILITY WILL SUPPORT SOME THREAT FOR SUPERCELLS/BOW
   ECHOES WITH THE PRE-FRONTAL CONVECTION THIS AFTERNOON.
  
   ...SYNOPTIC LOW ACROSS AR/TN/NRN MS AND AL LATE EVENING...
   THE PRE-FRONTAL CONVECTION WILL REDUCE INSTABILITY THROUGH THE
   MAJORITY OF THE INLAND WARM SECTOR ACROSS THE LOWER MS VALLEY BY
   MID-LATE AFTERNOON.  THIS WILL LEAVE A NARROW BELT OF SURFACE
   HEATING AND RESIDUAL MOISTURE ACROSS THE ARKLAMISS REGION LATER THIS
   AFTERNOON...ALONG THE SYNOPTIC COLD FRONT AND NEAR THE CYCLONE
   CENTER /WHICH IS NOW JUST W OF TXK/.  THIS REGION OF STRONG FORCING
   WILL THEN SPREAD EWD OVER NRN MS/TN/NRN AL THROUGH THE EVENING/EARLY
   TONIGHT.  THE MOST FAVORABLE WIND PROFILES FOR TORNADIC SUPERCELLS
   ARE EXPECTED IMMEDIATELY E/SE OF THE SURFACE LOW ACROSS THE MDT RISK
   AREA IN MS/AL...WHERE AN ISOLATED STRONG TORNADO OR TWO COULD STILL
   OCCUR LATER THIS EVENING.  THE PRIMARY UNCERTAINTY ACROSS NRN MS/WRN
   AND MIDDLE TN/NRN AL WILL BE THE DEGREE OF RECOVERY/ DESTABILIZATION
   IN THE WAKE OF THE AFTERNOON STORMS.


This is a dangerous situation, review all severe weather safety precautions, and stay tuned to your local media and local NWS office for up-to-date information.
