AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE TALLAHASSEE FL 359 PM EDT MON JUL 13 2015 .Near Term [Through Tonight]... The upper level high over the southern plains will keep us in an area of northwest flow overnight. Increased moisture from the east will keep PoPs higher than normal, around 30-40 percent, for the overnight hours. Lows will be in the upper 70s near the coast and mid 70s inland. .Short Term [Tuesday Through Wednesday Night]... On Tuesday, strong ridging is present over the Southern Great Plains. Meanwhile a deep trough is present over the Atlantic Seaboard with a shortwave trough moving through the Ohio River Valley. As a result, rain chances and cloud cover will be increasing. Afternoon showers and thunderstorms will be more numerous particularly for eastern portions of the region and along the seabreeze. With instability already in place, a few severe thunderstorms are likely with the main threat being damaging winds. A cool front will likely move in Wednesday night bringing nocturnal convection particularly near the coast. Tuesday, highs will be in the mid to upper 90s with heat indices from 102 to 108 degrees. Wednesday, highs will be in the mid 90s with heat indices of 102 to 106 degrees. .Long Term [Thursday Through Monday]... A more unsettled pattern will dominate the long term forecast. By Thursday, a deep trough will be over the Atlantic Seaboard with ridging present over the Lower Mississippi River Valley. The ridge will drift into the region by Friday. However, sfc features (weak low pressure and cold/stationary boundaries) will still be present to sustain the increased rain chances. The best chance for rain and thunderstorms will be in the eastern and southeastern counties of Georgia and Florida. Nocturnal convection is likely near the coast and over the Gulf. Expect this wet pattern to continue through the weekend as a cold front stalls out over the region. This pattern will bring some relief to the heat, particularly in the southeast portion of the region where rain and clouds will prevail. Afternoon highs will be in the low to mid 90s. && .Aviation... [Through 18Z Tuesday] VFR conditions will prevail at all terminals through the period. Included VCTS for scattered thunderstorms this afternoon, with the greatest chance at ECP and DHN. && .Marine... Light winds will become moderate and westerly by Tuesday afternoon. Winds will increase to cautionary levels by Wednesday morning along with 3 to 4 foot seas. By Friday, winds will become light to moderate again. An unsettled weather pattern will be in place this week, bringing increased chances for rain and thunderstorms. Some thunderstorms will likely have very gusty winds. && .Fire Weather... Hazardous fire weather conditions are not expected over the next several days. && .Hydrology... Area rivers remain below bankfull levels. Scattered showers and storms are expected this week, but heavy rainfall should be relatively localized. Flooding is not expected on any of the larger area rivers. && .Preliminary Point Temps/PoPs...
