Area Forecast Discussion National Weather Service Mobile AL 534 PM CST Fri Jan 17 2020

DISCUSSION. Updated for latest aviation discussion below.

AVIATION. 18/00Z Issuance . Low clouds just above MVFR criteria at many locations at the beginning of the period, but ceilings expected to drop below MVFR later this evening. Overnight, ceilings expected to near IFR, but overall should stay just above 1000-1500 feet at most locations. No fog that would obstruct surface visibility is expected through the period. Southeast to south winds around 10 knots tonight for most inland areas, but occasionally gusting to 15 to 20 knots at locations along the immediate coast. Winds near the coast will remain gusty into the middle part of the day on Saturday. /12

PREV DISCUSSION. /issued 345 PM CST Fri Jan 17 2020/

NEAR TERM /Now Through Saturday/ . In the wake of yesterdays cold front, surface high pressure will quickly move east over the Tennessee valley today. This will be in response to a strong shortwave trough moving across the Northern Plains into the Great Lakes region. A surface low will quickly track northeast into the Great Lakes tonight into the day on Saturday. Clouds will build from west to east this afternoon as the trough approaches and weak isentropic lift begins. A few showers and storms will begin late tonight into early Saturday morning over southeastern Mississippi and slowly move east. By midday Saturday, storms will increase in coverage as a stout cold front pushes through the area. Models are depicting some instability and a thunderstorm or two cannot be ruled out.

Temperatures today appear to be on track as clouds have limited the amount of daytime heating. A few locations east of I-65 may run a degree or two warmer than anticipated as clouds have moved a little slower than originally forecasted. Tonight, cloud coverage and increasing southeasterly flow will keep lows in the low 60s to upper 50s. Ahead of the cold front, temperatures will rise into the upper 60s to low 70s as low level warm air advection continues. A high risk of rip currents for all of our beaches through Saturday. BB/03

SHORT TERM /Saturday night Through Monday night/ . Precipitation will taper off from west to east Saturday night as the cold front sweeps through the forecast area and surface high pressure begins to build in from the northwest. Strong surface high pressure will continue to build into the region through the remainder of the short term. The large upper trough over the eastern conus will be reinforced late Sunday night and Monday as a vigorous, highly amplified shortwave dives south-southeast from the upper midwest states to the southeast. No precipitation is expected with the approach of the shortwave, despite the increased forcing, due to the very dry air mass in place. It will be much colder as temperatures drop through early next week, with highs Sunday in the upper 40s to mid 50s, and highs Monday in the mid 40s to lower 50s. Low temperatures will be in the mid 20s to lower 30s both Sunday and Monday nights. /22

LONG TERM /Tuesday Through Friday/ . Dry conditions will occur through midweek, followed by a return of isolated to scattered rain showers on Thursday and scattered to numerous rain showers with embedded isolated thunderstorms on Friday ahead of a southern jet stream upper trough moving east over the southern and lower Mississippi River region. Temperatures will be much below normal on Tuesday with highs in the mid 40s to lower 50s. Low temperatures will be in the mid 20s to lower 30s Tuesday night. A gradual warming trend will then occur through midweek with highs by Friday climbing back into the 60s. /22

MARINE . Surface high pressure will move east across the Tennessee valley tonight. Moderate to strong easterly flow will become southeasterly late tonight into early Saturday morning. A strong cold front will move through the area on Saturday bringing the chance for showers and storms. Behind the front, strong surface high pressure will build. As a result, moderate to strong northerly winds will develop in the wake of the front and persist into the middle of the week.

MOB WATCHES/WARNINGS/ADVISORIES. AL . High Rip Current Risk through Sunday afternoon for ALZ265-266.

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.
