Today: We’ll continue to see rain chances today. Gulf moisture will be brought in by southerly winds. This will keep dewpoints high, meaning it will remain feeling hot outside. It will also keep rain chances up in the forecast today. Scattered showers and thunderstorms are possible again this afternoon and evening, some of which could feature gusty winds and heavier downpours. Highs will be in the low-90s with the heat index in the low-100s. Partly cloudy skies, otherwise. Overnight you will see mostly clear skies with lows near 75 degrees.
Friday-Sunday: A strong ridge of high pressure will set up across our region leading to sunnier and drier conditions with hotter temperatures. Highs will top off between 95 to 98 degrees with the hottest day being Saturday. Isolated storms may occur, but the likelier possibility is no rain for Friday and Saturday. Heat index values could be very strong again and possibly approach heat advisory criteria. This high pressure system is also what will keep Tropical Storm Grace out of our hair and a problem left to Mexico.
Next Week: The high pressure system will weaken, allowing for rain chances to return but the heat will still stay strong.
Tracking the Tropics: Hurricane Grace will will impact the Yucatan Peninsula today then move over the Bay of Campeche. There it will make landfall in Mexico again late Friday before moving into the Eastern Pacific. A strong ridge of high pressure will prevent Grace from moving north.
Tropical Storm Henri is out in the Atlantic near Bermuda. It is expected to become a hurricane soon but will not impact us in Baton Rouge. The East coast is, however, keeping a close eye on it as it could impact New England on Sunday or Monday.
