Area Forecast Discussion National Weather Service Mobile AL 1137 PM CST Tue Dec 10 2019

DISCUSSION. Updated for latest aviation discussion below.

AVIATION. 06Z issuance . Ceilings have mostly risen to VFR levels across the region as of 11.06Z, but will likely become reduced to MVFR at times as a band of light to moderate rain spreads over the area through the overnight hours. A chance of rain will linger near the coast into Wednesday morning, where we will need to monitor for continued localized MVFR ceilings. Otherwise, VFR is expected to prevail during the day Wednesday. Northerly winds will continue to range between 10-15 knots with occasional gusts over 20 knots inland, and between 15-25 knots, with some gusts up to around 30 knots near the immediate coast overnight into Wednesday morning. /21

PREV DISCUSSION. /issued 928 PM CST Tue Dec 10 2019/

DISCUSSION . See updated information for land areas below.

UPDATE . Strong surface high pressure continues to build into the region this evening, resulting in breezy northerly winds across the forecast area. Wind speeds of 15-25 mph, with frequent gusts of 25-35 mph continue along the coast, where a Wind Advisory remains in effect overnight. We opted to extend the advisory through 12 noon CST Wednesday considering the continued tight MSLP gradient and potential for windy conditions along the coast through the morning. A narrow zone of enhanced moisture and ascent will continue to bring increasing coverage of a chilly light rain to the region tonight, particularly across southeast MS and interior southwest AL this evening and near the coast during the overnight and early Wednesday morning hours. /21

PREV DISCUSSION . /issued 548 PM CST Tue Dec 10 2019/

DISCUSSION . Updated for latest aviation discussion below.

AVIATION . 00Z issuance . Widespread MVFR conditions will prevail this evening, with a few localized IFR level ceilings in a few locations. Bands of light rain showers will move across the region this evening, with some increase in rain coverage possible near the coast late tonight through early Wednesday morning. Ceilings are otherwise forecast to gradually lift to VFR thresholds across the region Wednesday morning. Northerly winds of 10-20 knots with some gusts between 25-30 knots will persist through Wednesday morning. /21

PREV DISCUSSION . /issued 412 PM CST Tue Dec 10 2019/

NEAR TERM /Now Through Wednesday/ . A large surface high pressure area over the Great Plains will move just east of Mississippi River Valley by late Wednesday afternoon while strengthening to around 1035 mb. This will reinforce the northerly winds and cold dry airmass across the region in the near term in the wake of today's cold front. Despite the passage of the fast moving cold front moving away from the area, scattered numerous showers will remain overnight as an upper shortwave over the southern plains moves east toward our region. The precipitation will taper off Wednesday west of I-65, but scattered showers east of I-65 will remain throughout the day. Skies will also gradually clear from west to east midweek. Despite the added sunshine, the additional cold air advection will help offset the daytime surface heating. So, high temperatures Wednesday will be about 9 to 14 degrees below normal, ranging from 51 to 56 degrees. Low temperatures tonight will be near normal, ranging from 34 to 42 west of I-65, and from 42 to 47 to the east. /22

SHORT TERM /Wednesday night Through Friday night/ . An upper level trough continues to slide across the northeastern states Wednesday night as high pressure at the surface builds into the eastern half of the CONUS in the wake of the trough. Winds turn northeasterly then easterly at the surface Wednesday night and Thursday in response to the shifting high to our north. However, the area remains on the west side of the mid to low level ridge over the western Atlantic, so winds in the mid levels remain southwesterly. This will set the stage for an overrunning pattern and rain chances start increasing again by Thursday. Rain chances remain high overnight Thursday into Friday as another shortwave trough slides through the region and a surface low slides northeast across the coastal waters.

Thursday will be chilly and overcast with scattered rain showers moving into the area, especially by the afternoon hours. Temperatures on Thursday will only top out in the mid to upper 50s inland, while struggling to reach 60° near the coast. Friday will be slightly warmer, although still overcast. Cloud cover and rain will allow the overnight temperatures to progressively get warmer as we go through the work week. Thursday morning lows will range from mid to upper 30s across the northwestern half of the area to upper 40s across the Florida panhandle while 5°-10° warmer by Friday morning.

The risk of rip currents will remain MODERATE through Thursday night before falling to LOW on Friday. 07/mb

LONG TERM /Saturday Through Tuesday/ . Another trough slides through the region early on Saturday before lifting off to the northeast through the day. This will allow zonal flow to briefly set up across the region through Sunday afternoon as mid and upper level ridging builds into the Gulf. The area will briefly dry out in the Saturday night through Sunday timeframe. Winds turn more southerly at the surface on Sunday ahead of the next system and the ridge loses its grip on the area on Monday. The next upper level trough slides across the Plains on Monday. A surface low forms somewhere in the Southern Plains by Monday afternoon and quickly lifts off to the northeast through the overnight hours. This will bring increasing rain chances early in the work week as a cold front pushes across the area overnight Monday into early Tuesday. 07/mb

MARINE . Moderate to strong northerly winds in the wake of a cold front will continue into Wednesday. Winds become northeast to east but remain moderate to strong Wednesday night through Thursday as a strong high pressure system expands across the eastern states. Winds will then relax late in the week. /22

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
