Area Forecast Discussion National Weather Service Mobile AL 1149 PM CDT Tue Mar 31 2020

AVIATION. 06Z issuance . VFR conditions will continue with a north-northwest wind at 10 to 15 knots diminishing to around 10 knots by mid- morning. BB/03

PREV DISCUSSION. /issued 943 PM CDT Tue Mar 31 2020/

NEAR TERM /Now Through Wednesday night/ . Relief at last, relief at last! The near term looks cool and dry in the wake of the upper trough that brought severe weather across the area today. Since there is not much to talk about I will keep this short and sweet. The upper trough will continue to push east through tomorrow as surface high pressure builds over the central US bringing below seasonal temperatures and a couple days of dry weather. Winds should being to weaken through the night tonight as the ridge begins to build. With dewpoints already crashing into the 40s, temperatures will quickly follow leveling out in the 40s, yes I said 40s, tonight and tomorrow night. Despite the cool start, clear skies and dry column will allow for temperatures to warm up into the low 70s but still rather nice. This should persist into the short term. BB/03

PREV DISCUSSION . /issued 630 PM CDT Tue Mar 31 2020/

NEAR TERM UPDATE /Now Through Wednesday night/ . Severe clear has developed in the wake of todays storms. Winds will remain gusty into the evening but should fall below wind advisory criteria at as the surface decouples with sunset. Otherwise we still expect cooler temperatures with dewpoints already in the 40s. Enjoy the dry weather and the sunset tonight! BB/03

AVIATION . 00Z issuance . VFR conditions through the forecast period. Winds will remain out of the north at around 10 knots with gusts to 15 to 20 knots through midnight before relaxing late tonight into early tomorrow morning. BB/03

PREV DISCUSSION . /issued 358 PM CDT Tue Mar 31 2020/

NEAR TERM UPDATE /Now Through Wednesday/ . This morning's convection has shifted to southern-most portions of the marine area, with the passing cold front having moved south of the coast. Cooler, drier air has begun to move over the forecast area, with a band of post-frontal stratocu moving over the forecast area at this time. /16

************************** Previous *******************

A large area of strong to severe thunderstorms located over the lower part of the forecast area generally south of a line from south Mobile Bay to Crestview Fl will continue to shift south and east through mid to late this afternoon then move east of the area by early this evening. This area of convection is associated with a potent short wave trough tracking east over the northern Gulf states earlier this morning and this afternoon progged to exit to the east over GA and the Carolinas by early this evening. Near the surface a broad area of low pressure located on the base of the trough will also track east of the region by mid to late afternoon with a trailing cold front stretching to the southwest from the low center, moving south across lower MS and AL by mid to late this afternoon, also. With this pattern both the best instability and vertical shear will continue to shift towards the NWFL coast through mid afternoon then slowly shift offshore through early this evening. By late tonight into Wed the main short wave trough will move off the eastern seaboard followed by a sharp ridge moving from east TX to the lower MS River Valley mostly during the day on Wed. Skies will begin to clear this evening generally from west to east leading to mostly clear skies overnight and early Wed morning followed by plenty of sunshine during the day. Expect gusty west to northwest winds ahead and in the wake of the cold front late this afternoon and early this evening slowly diminishing overnight through mid morning Wed. As a result the Wind Advisory that is in effect for the lower half of the forecast area will expire by 7 pm CDT this evening.

Temperatures are expected to return to near seasonal levels tonight and during the day on Wed with lows ranging from the middle to upper 40s for most inland locations and the lower to middle 50s along the immediate coast. Highs Wed will range from the lower to middle 70s for all locations. 32/ee

SHORT TERM /Wednesday night Through Friday night/ . An upper level ridge will build north along the Mississippi River from upper level high pressure over the Gulf of Mexico. Increasing upper subsidence from the upper ridge will bring a return of above seasonal temperatures to the forecast area by Friday. A surface ridge stretching north along the Mississippi River will quickly shift east to near the Eastern Seaboard in response to the building upper ridge before becoming under the influence of another well developed system over the western Atlantic. The influence of the western Atlantic system will help to disorganize the surface ridge some as it stalls, but the surface ridge maintains enough organization to create an east to southeast flow to bring Gulf moisture inland.

Looking at the numbers, low temperatures generally in the 40s rise to mid to upper 50s Friday night. High temperatures in the mid to upper 70s are expected Thursday, with upper 70s to low 80s expected Friday. /16

EXTENDED TERM /Saturday Through Tuesday/ . A series of upper level disturbances will move through the southern end of the upper ridge (and the lower Mississippi River Valley and Southeast), initially weakening the upper ridge somewhat. The ridge does maintain its strength enough to keep temperatures at above seasonal norms through the extended. Looking at rain chances, for Saturday, best moisture return is initially over the Lower Mississippi River Valley as the shortwave energy begins to pass. For the forecast area, this coverage will encroach over the forecast area from the west, with best rain chances remaining west of the Alabama/Mississippi State line. The best rain chance shifts south to the southern half of the forecast area and coastal waters as the the first shortwaves move along the northern Gulf coast Saturday night into Sunday. The upper ridge builds again Sunday night on, shifting the path of the passing shortwave energy north. The best chance of rain shifts north with the building ridge, with best chance being over the northern half of the forecast area and areas north. /16

MARINE . Strong northwest to northerly wind flow and building seas are expected the rest of this afternoon into tonight behind a strong cold front. The strong flow is expected to slowly diminishing late Wednesday morning through Wednesday night. A light southeast to southerly flow can be expected through the remainder of the week as a surface ridge of high pressure builds over north central and eastern Gulf. /16

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.
