Monday was unusually warm and humid for Tampa Bay and the rest of west-central Florida, given the area has entered into the latter part of October. Morning lows ranged from 73 degrees at MacDill Air Force Base up to a balmy 78 degrees in St. Petersburg.
Under partly sunny to mostly cloudy skies afternoon highs climbed into the upper 80s area-wide. These temperatures, when combined with dew point temperatures in the lower 70s, produced heat index readings in the lower 90s for part of the afternoon.
Scattered showers and thunderstorms developed in warm and humid air mass across Tampa Bay on Monday. However, most storm development remained east of the Interstate 75 corridor, and no measurable precipitation was recorded at any of the major reporting stations across west-central Florida.
One more somewhat summer-like day forecast for Tuesday
The mostly cloudy, warm, and rather humid weather pattern with scattered showers and thunderstorms will persist across the area through early Wednesday. By Wednesday afternoon, the first significant frontal boundary of the fall season will bring cooler and drier weather into Tampa Bay and the rest of west-central Florida.
Forecast for Tampa Bay through the weekend
The forecast for Tuesday through early Wednesday in Tampa Bay calls for patchy fog, with precipitation coverage ranging from 30 percent to 50 percent through the period. Morning lows both days will range from 70 to 77 degrees, with highs between 85 and 90 degrees Tuesday afternoon under mostly cloudy skies.
By Wednesday afternoon, skies will begin to clear as the cooler and drier weather air mass flows across west-central Florida. With the passage of the front, rain chances diminish significantly. Temperatures by Thursday morning will cool substantially below what is expected across the area for Tuesday and Wednesday mornings.
Highs for the period Wednesday through Monday will range from 80 to 85 degrees under mostly sunny skies. Morning lows will range from 58 to 68 degrees depending upon proximity to Tampa Bay and the Gulf of Mexico. No precipitation is forecast between Thursday and Monday, and humidity levels will remain low.
Tropical Storm Lorenzo not a threat
Tropical Storm Lorenzo developed over the central Atlantic Basin Monday evening. However, the system is expected to be rather short-lived, and will not affect land. For more information on the tropics, please visit the National Hurricane Center website.
