...Heat Advisory in effect for Today and Wednesday...

Short Term Forecast:  It feels very oven-like when you step outside this morning!  We have mostly clear skies with temperatures in the upper 70s to lower 80s.

It is going to be a sizzler again this afternoon across the Baton Rouge area.  The area of high pressure remains over the Southern Plains States and that means we will stay very hot and humid.  The eastern edge of the high pressure is located over Mississippi and Alabama, and that is where showers and storms are expected throughout the day.  A stray storm could make it over to Baton Rouge today, but most of you will not see any rain.  High temperatures will be in the mid 90s and the heat index will be 105 to 110 at times.  Due to the extreme heat, the NWS has issued a Heat Advisory for all the the WBRZ Viewing Area this afternoon. 

We will not see much of a cool-down tonight with partly cloudy skies and low temperatures in the upper 70s.

Week Ahead:  More heat with little to no rain is in the forecast again for Wednesday and Thursday as the ridge of high pressure remains in place west of Louisiana.  The NWS has extended the Heat Advisory to cover tomorrow as well since we will have highs in the mid 90s and the heat index 105 to 110. We could see a stray storm, but that would be the only relief from the heat.  Wednesday night will be partly cloudy and muggy with lows in the upper 70s.

At this time, there is not a Heat Advisory for Thursday.  However, it will stay partly cloudy and hot with only a few storms possible.  Highs will be in the mid 90s and lows in the upper 70s.

There is going to be a slightly better chance of rain on Friday as the ridge of high pressure moves back to the west.  We will have partly cloudy skies with isolated showers and thunderstorms.  It will stay hot with highs in the mid 90s and lows in the mid 70s.

Weekend Outlook:  The forecast models are showing that we will have a few weak disturbances that will move across Southeast Louisiana this weekend.  When you combine that with daytime heating and the sea breeze that is going to give us a better chance of rain with scattered showers and thunderstorms.  High temperatures will be in the lower to mid 90s and lows in the mid 70s each day. 

Tropical Outlook:  I'm still watching a weak area of low pressure associated with a tropical wave located about 1100 miles WSW of the Cape Verde Islands.  It is producing disorganized showers and thunderstorms at this time.  Conditions are somewhat favorable for additional development over the next few days it is moves to the west at 10 to 15 mph.  NHC is giving it a low chance, 20%, of becoming a tropical cyclone during the next 48 hours.

Elsewhere...there is a weak tropical wave moving through the Puerto Rico area, but there is only a slight chance that is could develop into anything. 

The rest of the tropics are quiet, and tropical cyclone formation is not expected in those areas through Wednesday.

Please keep cool and stay hydrated today! Have a good one! -Dave
