Area forecast discussion, Jun 13, 2:43 PM CDT, 1 hour 15 minutes before
Area Forecast Discussion National Weather Service Tallahassee FL 343 PM EDT MON JUN 13 2016 .NEAR TERM [Through Tonight]... Upper level ridging across the CWA breaks down tonight as a weak shortwave across the Mississippi Valley this afternoon slides eastward tonight. Convection has developed this afternoon and a few strong to severe storms are still possible. Expect activity to diminish after 02z, with a few thunderstorms across the coastal waters and the western portion of the CWA possible late tonight. Low temperatures tonight will be above normal with lows in the low to mid 70s. .SHORT TERM [Tuesday Through Wednesday Night]... Unsettled weather with above average thunderstorm chances are expected to continue as a weak trough traverses the region, advecting deep moisture across the region. The latest operational guidance continues to indicate precipitable water values rising above 2 inches Tuesday afternoon into Wednesday. However, the lack of substantial forcing should limit any widespread heavy rainfall potential. Nonetheless, locally heavy rainfall will be possible with thunderstorms. The environment will be favorable for isolated severe thunderstorms, with marginally severe microbursts being the most likely hazard. Heat indices will exceed 105 degrees F in portions of the area Tuesday, with southeastern portions of the forecast area approaching the heat advisory criteria of a 108 degree heat index by Tuesday afternoon. .LONG TERM [Thursday Through Monday]... Unsettled weather is expected to continue through Friday before a trailing cold front is expected to scour out some moisture for the weekend. Ample deep layer moisture in place prior to the frontal passage will keep heat indices ranging from the upper 90s to lower 100s during the mid to late afternoons. && .AVIATION [Through 18Z Tuesday]... Scattered thunderstorms are expected this afternoon into the evening around the TAF sites. Activity should diminish by 02z. Outside of any thunderstorm activity, VFR conditions are expected. && .MARINE... Typical summertime conditions expected to continue through Wednesday, with an afternoon sea breeze and chances for thunderstorms near the coast. Westerly winds and seas are expected to increase Thursday and Friday ahead of an approaching cold front, with exercise caution conditions possible by late Thursday into Friday and potentially small craft advisory conditions developing by late Friday. Winds are expected to shift and decrease into the weekend. && .FIRE WEATHER... No fire weather concerns are anticipated through the period as a moist airmass remains in place over our area. RH values are not expected to dip below 40-50% any day this week. && .HYDROLOGY... Locally heavy rainfall from scattered showers and thunderstorms over the next several days could lead to localized flooding of low lying and poor drainage areas, especially in urban locations. However, significant rises on the local river system are not anticipated from this activity. && .PRELIMINARY POINT TEMPS/POPS...
