NEAR TERM. (Tonight) Issued at 250 PM CST Sat Dec 7 2019
Latest visible satellite imagery and RAP H5 analysis showed relatively zonal flow in place aloft and two domes of high pressure at the sfc: one over the SErn Great Lakes region, and the second centered over Cntrl AR. It's the latter of these 2 ridges that will shift Ewrd toward the TN Valley tonight. This will cause sfc winds to become more Srly, which will increase moisture and keep dewpoints during this time in the lower 40s. In addition, clouds will redevelop and creep into the area tonight, keeping morning lows mild and skies eventually mostly cloudy by sunrise. Lows Sunday morning will fall into the 41-46F range.
SHORT TERM. (Sunday through Monday night) Issued at 250 PM CST Sat Dec 7 2019
A pattern change is on the horizon as the ridge shifts E of the TN Valley, with the first of which being a vort lobe wobbling thru zonal flow aloft associated with a large upper low over the Srn Canadian Provinces. The second is a one-two-punch of systems early next week.
A vort max rounds the base of the large upper trof in place in CAN, skirting energy across the Great lakes Monday. This should drop a weak front N of our area ahead of another low deepening across the Desert SW after coming ashore in SOCAL. This system will deepen somewhat and traverse the SWrn U.S., bringing more widespread rain chances to the area as early as Monday night, but especially during the day Tuesday. A few isolated storms are possible overnight Monday into Tuesday as the CWA finds itself 'in-between systems' with pretty decent return flow ahead of the stronger/second system, but otherwise, no strong/severe storms are expected.
Temperatures during this time will be mild, topping out in the upper 50s Sunday and the mid/upper 60s Monday. Morning lows will be mildest Monday morning, falling into the upper 40s and lower 50s, with a tad more colder air trying to intrude for morning lows on Tuesday. Lows during this time will range from cooler NW/warmer SE, with values in the lower 40s NW and the lower 50s SE.
LONG TERM. (Tuesday through Friday) Issued at 250 PM CST Sat Dec 7 2019
An active pattern still looks likely for the extended period. A stronger trough axis will swing east into the southeastern US keeping rain chances in the forecast through Tuesday night. Thermodynamic profiles were not convincing enough to include any mention of thunder on Tuesday morning at this time, and this has been fairly consistent among guidance over the last several days. Some minor discrepancies regarding timing of the cold front's arrival in northwest Alabama are evident amongst this mornings runs, with the GFS and Canadian being a little faster. These differences are minimal, however, and we should expect the front to arrive in northwest AL by sunrise and track east through northeast AL by early afternoon.
A considerable amount of uncertainty exists regarding how quickly the cold air arrives and whether or not there will be any wintry precipitation early Wednesday. Blended guidance appeared to be a little too aggressive bringing in colder temperatures, resulting in a bit of a snow bias. Thinking this is a bit overdone right now, so will only mention a small chance of a rain/snow mix or perhaps a few flurries early Wednesday, but want to reiterate that confidence in this remains very low and no accumulations are expected at this time.
Much cooler air arrives behind the front, and low temperatures will drop near or a few degrees below freezing with highs in the mid to upper 40s through the end of the work week. Will end the week with another deep trough over the southeastern US. This will bring chances for rain and perhaps another shot at some wintry mischief, but will wait for guidance to reach better agreement before discussing any further.
AVIATION. (For the 18Z TAFS through 18Z Sunday afternoon) Issued at 121 PM CST Sat Dec 7 2019
VFR conds and clear skies will dominate the first half of the TAF period at both terminals, and then clouds return for the latter half. Winds will be the bigger story of the period, remaining light/variable AOB 5kts thru about 08/10Z at both sites, and then quickly increasing to sustained 10-15kts gusting to 20-25kts at times shortly after daybreak. Wind gusts will remain in place thru the end of the TAF period Sunday.

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.
