Area Forecast Discussion National Weather Service Tampa Bay Ruskin FL 229 PM EDT Sun Jun 11 2017 .SHORT TERM (Tonight - Monday)... In the mid/upper levels, troughing extends south through the western Atlantic with another trough over eastern Texas extending into the western Gulf of Mexico. Mid-level ridging extends northwest from eastern Cuba to the southeast U.S. Another trough over the western U.S. will slowly move eastward and deepen through the beginning of the week. In turn, upper ridging will build over the southeast U.S. and become the dominant upper feature through the period. On the surface, the front that was over southern Florida yesterday continues to wash out with some lingering showers and storms over the coastal waters. High pressure in the western Atlantic ridging westward will become the dominant weather feature over the area for the next several days. This will cause the seasonal sea breeze storms to form over the east coast and traverse westward colliding with the west coast sea breeze over the interior counties. Abundant moisture with PW values in excess of 2 inches will be advected over the region through the period which will keep rain chances high (40- 70%) through the afternoon/evening hours. Temperatures will be just around seasonal averages for daytime highs and overnight lows. && .LONG TERM (Monday Night - Sunday)... Models remain in good agreement with synoptic scale features during the long term period so a blend will continue to be used. Strong upper ridging over the mid Atlantic coast will shift east offshore the mid Atlantic coast through mid week as a weakening upper level trough now over the western Gulf drifts eastward along the Gulf coast to be located over the southeastern states and eastern Gulf by Wednesday. At the surface the Bermuda high pressure area over the Atlantic and extending west across the southeastern states will maintain a deep layered east-southeast wind flow across the entire forecast area. Deep tropical moisture (PW's around 2 inches) within the east to southeast wind flow around the surface high will continue to support numerous diurnal sea breeze driven showers and scattered storms across the forecast area each day, with an east-southeast steering flow favoring highest rain chances (Pops 60-70 percent) over the western half of the forecast area during the afternoon and evening hours, with some locally heavy rainfall possible. During the second half of the week and into next weekend upper and surface ridging will weaken and shift east-southeast into the Atlantic as upper level troughing become more pronounced over the southeastern states and Gulf. Deep tropical moisture (PW's 2 inches) will remain in place which will continue to support numerous diurnal sea breeze driven showers and thunderstorms (Pops 60 to 70 percent) across the forecast area each day, with a weaker south to southwest steering flow favoring the highest coverage of storms shifting to inland locations each afternoon where the sea breeze collision will take place. The abundant moisture and slow moving storms will favor locally heavy rainfall amounts in some locations each day. Considerable cloud cover combined with the rain chances will keep daytime temperatures near or a few degrees below seasonal norms with highs in the mid to upper 80s each day, while overnight lows will run a few degrees above normal with lows generally in the lower to mid 70s. && AVIATION... VFR conditions will prevail at all terminals through the period. The only exception will be with passing showers and storms during the afternoon hours. Some brief periods of MVFR/IFR for cigs/vsby will be possible in storms. Have put VCTS at all terminals starting at 21Z and will cover any restrictions with TEMPO groups based on radar coverage. No other aviation impacts expected. && .MARINE... The front that was over Florida has washed out and high pressure ridges west across Florida and into the Gulf of Mexico. This will produce an east through southeast wind flow into next week, but is expected to remain less than 15 knots with seas less than 3 feet through the period. With the east-southeast winds, any shower/storm activity over the coastal waters will occur later in the day during the evening hours. No other marine impacts expected. These storms will be capable of producing strong gusty winds, locally rough seas, and frequent cloud to water lightning. No other marine impacts expected. && .FIRE WEATHER... No fire weather hazards are expected through the period as minimum relative humidity values are expected to remain above critical levels each afternoon.. && .Preliminary Point Temps/PoPs...
