Area Forecast Discussion National Weather Service Mobile AL 633 AM CDT Thu Oct 1 2020

NEAR TERM UPDATE /Now Through Friday/. An upper level trough over the eastern CONUS will stay fairly stationary but amplify through the near term period. Meanwhile, a reinforcing surface cold front will progress over the southeastern CONUS during this time, with passage over the local area this afternoon and evening. This feature is not expected to bring much precipitation or clouds, but usher in cooler, drier air as well as increased northwesterly winds down into the deep south by late week. Thus, dry and clear conditions will prevail through Friday. Highs Today will be a tick warmer than they were yesterday given the slightly warmer air and compressional warning in advance of the approaching front. Behind the front, winds will quickly turn out of the north and temps will fall into the mid to low 50s. With the drier and cooler air continuing to move in Friday, highs will likely remain on the low side with areas struggling to reach the upper 70s. A LOW RISK of rip currents will also continue through the period. /26/03


AVIATION. 12Z issuance . VFR conditions will persist through the period with clear skies. Winds will be light out of the northwest becoming north this evening. BB/03

PREV DISCUSSION. /issued 401 AM CDT Thu Oct 1 2020/

NEAR TERM UPDATE /Now Through Friday/ . An upper level trough over the eastern CONUS will stay fairly stationary but amplify through the near term period. Meanwhile, a reinforcing surface cold front will progress over the southeastern CONUS during this time, with passage over the local area this afternoon and evening. This feature is not expected to bring much precipitation or clouds, but usher in cooler, drier air as well as increased northwesterly winds down into the deep south by late week. Thus, dry and clear conditions will prevail through Friday. Highs Today will be a tick warmer than they were yesterday given the slightly warmer air and compressional warning in advance of the approaching front. Behind the front, winds will quickly turn out of the north and temps will fall into the mid to low 50s. With the drier and cooler air continuing to move in Friday, highs will likely remain on the low side with areas struggling to reach the upper 70s. A LOW RISK of rip currents will also continue through the period. /26/03

SHORT TERM /Friday night Through Saturday night/ . A broad upper level trough continues across the region. At the sfc a light northeast to east flow will maintain a dry airmass. The result will be continued clear skies and dry conditions. Temperatures will remain below normal with lows Friday night in the upper 40s and low 50s inland to upper 50s near the coast. Highs on Saturday will be in the low to mid 70s. Lows Saturday night fall into the low to mid 50s inland to upper 50s to near 60 along the coast. /13

EXTENDED TERM /Sunday Through Wednesday/ . There are timing and evolution uncertainties as to how quickly an upper trof over the eastern states moves off into the western Atlantic between Monday into Monday night, which in turn affects whether or not a surface low moves across the interior eastern states. Depending on how this plays out, it's possible that a weak reinforcing cold front will move through the forecast area Sunday night, but it's actually of no consequence as deep layer moisture remains too low to support a mention of precipitation, much less much in the way of cloud cover. A surface ridge will be over the southeastern states Monday and Tuesday then weakens on Wednesday but still promotes a light northeasterly flow over the forecast area through the first half of the work week with a dry forecast continuing. Highs on Sunday will be mostly in the upper 70s then mid to upper 70s follow for Monday. A warming trend then ensues with highs on Wednesday reaching the lower 80s in most areas. Lows Sunday night and Monday night primarily range from the mid 50s inland to near 60 at the coast, then trend warmer by Tuesday night with mostly upper 50s inland ranging to lower 60s at the coast. /29

MARINE . Winds and seas will remain light today before increasing tonight into Friday. A small craft advisory is in effect for southern Mobile Bay, the Mississippi sound and the coastal waters out to 60 nautical miles. Winds will come down below criteria on Friday but moderate north to northeasterly flow will continue through the weekend. Given the short fetch, waves will slowly build to around 2 to 4 feet offshore and remain there through the weekend. We will have to watch the potential of a tropical system entering the southern Gulf this weekend which could lead to increased seas as we head into next week. No rain is expected through the weekend. BB/03

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.
