Area Forecast Discussion National Weather Service Tallahassee FL 627am EST Fri Nov 22 2019 Near Term - Through Today The surface high pressure currently in place over our region, is expected to quickly exit off the east coast of Florida during the day Friday. This will give way for the next system to impact the region over the weekend. During this time, surface winds will become southerly, which will help push temperatures across the region to the mid 70s. Although no precipitation is expected Friday, increased mid-level moisture advected into the region from the system to our west will maintain cloudy conditions for much of the day. .SHORT TERM [Tonight Through Sunday Night]... The ridge aloft breaks down tonight with two distinct upper lows, one over KS and one in Canada north of NY. The first low will drag a front back to its southwest but by the time the front gets this far east, the low is too far north and east for the front to push through our area. Meanwhile, the other upper low from KS brings a cold front east. Before the front, winds turn southerly and we are able to get moisture back into the region with dew points back into the 60s. This front should bring widespread showers, with the western areas seeing rain by Saturday morning and the rain exiting the Big Bend after midnight Sat night. Lows tonight with the southerly flow will be in the lower 50s to lower 60s with highs Sat in the 70s. Behind the front Sat night, clouds will be slow to clear so temps only fall to the upper 40s to mid 50s. Northwest flow returns on Sunday with cooler air returning. Highs Sunday will be in the lower to mid 60s with lows Sunday night falling into the upper 30s to mid 40s. Long Term - Monday Through Friday The work week starts out dry with weak surface high pressure over the region and near zonal flow aloft. Heigheights start to rise through Tuesday night as another weak frontal system approaches on Wed. The upper and surface low are both near the Great Lakes Wednesday morning, and even though moisture recovery will generally be good, the lack of lift is making it difficult to put any higher than chance probability of precipitation in the forecast. Behind that, another ridge builds across much of the country with a deepening trough over the west shooting a few shortwaves eastward along the ridge The GFS shows this solution which would keep rain in the forecast for Thursday, with the ECMWF dry Thu-Fri. Temps will generally be on the rebound with highs Monday in the upper 60s and up to mid 70s for Tue/Wed. Thu/Fri will see highs in the upper 60s to the north, lower 70s to the south. Lows Monday night will range from the lower 50s on the coast to lower 40s in the north and warm into the lower to mid 50s for the rest of the week. Marine Southerly winds of less than 10 knots will continue until Saturday when a front approaches and moves across the waters with widespread rainfall. Winds shift to the northwest with speeds of 15 to 20 knots and seas of 3 to 5 feet. It looks like we won't need a Small Craft Advisory at this time but that will continue to be monitored. For the start of the week, winds remain less than 10 knots with seas of 1 to 2 feet. Fire Weather Hazardous fire weather conditions are not expected. A cold front is expected to pass through the region on Saturday, which will bring the chance for light precipitation to the region. Winds ahead of the front will be southerly with possible gusts up to 20 mph. Dispersions will be elevated Saturday, but are not expected to be a concern. Hydrology A cold front should bring widespread rain for most of the area on Saturday but we are only expecting less than a half an inch of rain. Another system will impact the region through the middle of the week but only light accumulations are expected. There are no flooding concerns through the next 7 days.
