At the sfc, a stronger cold front compared to the one last night/earlier today is expected to move into northern OK late tonight/early Friday and continue to move exiting the fa around mid-day tomorrow.
Overnight, cloud cover will increase as a cold front approaches the area. Low temperatures will feature a pretty large gradient, with areas that are able to experience the frontal passage being much cooler than areas that do not. (Friday through Thursday) Gusty northerly winds and much cooler air will advect into the area Friday.
(This evening through Friday) The FA will remain rather warm tonight as 10 mph southerly winds become more westerly through the night ahead of an approaching cold front with lows averaging in the mid 30s to upper 40s. Currently, this cold front is expected to push into the FA shortly after sunrise and exit our southern counties before 18Z.
Moisture begins to increase in the deep southwesterly flow that will be developing across the region, as a cold front approaches the forecast area from the northwest. Lows tonight will be a little warmer than last night, ranging from the mid 40s over most inland locations of AL and the Fl panhandle, but upper 40s to around 50 over interior southeast MS. On Friday highs will mainly be in the mid 60s across the entire region, but in the upper 60s, possibly pushing 70 degrees, up over the northwestern portions of our area along and north of the Highway 84 corridor.
A light S/SW flow regime in the lower levels is also in place over much of the region, with high pressure now located in the southern Atlantic Basin. This return flow pattern has allowed temps to climb into the lower/mid 60s and these temps will likely climb a couple of more degrees before the onset of the evening hrs. Mid/high cloud cover will continue to spread more into the area tonight, as overnight lows trend in the lower/mid 40s, which are around 10F warmer compared to this morning.
Quiet and dry weather tonight and Friday under high pressure.

At the surface, impact of the cold frontal passage last night has been mixed, with the northeastern third mired under stratus all morning, with these areas likely to struggle to reach 50. Elsewhere, with lee troughing resuming due to the quick approach of the S NV wave, southerly winds are occurring. Farther north, a cold front associated with the 49th parallel upper trough is beginning to push southward through MT/ND. Tonight into tomorrow, MT/ND cold front will dive southward, with most guidance having this through much of the CWA by sunrise.

(Tonight through Friday) High pressure remains over central Alabama late this evening. A cold front will swing through Friday night bringing a rather quick shot of rain and cooler conditions. 75 Previous short-term discussion: (This afternoon through Friday) High pressure to the south of the area will slowly move east through the short term as a low pressure moves into the Ohio Valley late Friday. Winds Friday will be breezy ahead of that low pressure system, with gusts in the 15-20 mph range beginning in the afternoon and lasting through the evening.
A cold front will sink south over the Florida peninsula on Saturday, and will stall across south Florida late in the day.
The cooler airmass lagged well to the northwest of the FA, with the leading edge situated roughly along the I-44 corridor. Mid aftn temps were already running a good 10 degrees abv normal in many areas, ranging fm the lower 60s to near 70. While the wind shift, associated with the aforementioned bndry, may make some more progress to the south, the cooler airmass will stay to the north of the FA tngt. Most locations wl drop below the freezing mark by Sat mrng.
This will be a cold front that will be on the colder side due to this airmass having some arctic influences. The amplified pattern initially will showcase the stout ridge over the Rockies that will help drive down the cold airmass. Despite the stout ridge, the actual core of the cold will be over the Midwest. In the wake of the cold front, look for sustained winds across our NW/W areas to be around 20mph and gusts 25-35mph. Tue we will push 65-73 for MaxT if not a bit warmer. This will easily support 72-78 each day if not warmer. To get warmer, it will depend on clouds/lack of clouds.
- Cold front Saturday morning will lead to moderate to strong northerly flow late Saturday. Rain chances will diminish late Friday night through Saturday as a cold front advances across the area, though showers will linger across the coast. Temperatures will be cooler today as dense cloud cover keeps the sun at bay and showers persist. Temperatures will be even cooler Saturday behind the cold front with highs in the low to mid 50s.
Ridge axis along the west coast this evening will shift east across the Great Basin tomorrow. However, ridge will be quite 'dirty' as a variable amount of mid/high clouds associated with eastern Pacific trough pass overhead. Clouds look to have little impact on our temperatures Friday and Saturday as reading should be 1-3 degrees warmer than today.
Next midlevel trough swings through the region on Friday and will cause a period of light snow.
1144 PM CST Thu Feb 15 2024 (This afternoon through Friday night) The Big Story is the timing and temperature impacts of a shallow Arctic cold front Friday.

Temperatures along the Island Chain are in the lower 70s with dew points in the lower to mid 60s. From synopsis, high pressure will continue moving further offshore into the western Atlantic overnight through Friday. Breezes will turn to the south and southwest Saturday and Saturday night, ahead of another approaching cold front.
Freezing levels will lower into the evening and a changeover to snowfall is expected in the evening. Otherwise, the snowfall window looks rather brief with temperatures being near to just above freezing with the ongoing snow. Areas along the Highland Rim and northern Plateau could perhaps see up to one half inch in a few spots. Low temperatures will dip below freezing by 7 am and will be in the upper 20s to near 30. Given the amount of residual moisture on our roadways, a slick spot or two could reside especially along bridges and overpasses.
917 PM CST Thu Feb 15 2024 A weak cold front has pushed south to about a Jonesboro, AR to Huntingdon, TN line this evening. A cold front will move into the Mid-South tonight and then stall out across the region Friday morning.

The cold front will move out of the region Friday night bringing much colder air for Saturday.
(Today through Saturday) Our stretch of quiet weather will be coming to an end today as a quick moving cold front pushes through Middle TN. We will see a quiet start to the day though with warmer morning temperatures than the last few mornings. Upper level trough will dig into the Great Lakes pushing a cold front south into the region later today into the evening.
This high will drop to the southeast as our air mass dries out today. Cold high pressure will remain over the region keeping temps colder than normal, with highs in the mid teens to lower 20s, and decreasing clouds. Though the mid and upper level northerly flow will be light, tightening downslope gradients w/ high pressure/cold air to our west & southwest will result in breezy conditions developing along the western foothills. JKL Upper level ridging over the region will persist into mid-week.
-Warmer, dry on Friday. Amid light winds overnight, temps should fall into the low and mid 50s over the rural interior. ) High pressure over the western Atlantic will slowly shift eastward through the day on Friday.
The increase in cloud cover will help keep temperatures warmer than last night. This will be a cold front that will be on the colder side due to this airmass having some arctic influences.

1235 AM EST Fri Feb 16 2024 High pressure will remain in place through Friday before a cold front moves through on Saturday.
OVERVIEW: broad upper level trough in control of the regional weather as we move through the weekend. Milder air returns for at least the first half of the new week with broad upper level ridging/height increases on the docket. How long the warming sticks around is uncertain with spread between the models increasing as we move toward the following weekend (ridging or troughing?). Colder, but more seasonable air drops southward out of Canada today, post the cold front that brought the rain and accumulating snow to the region. With an upper level trough remaining the main weather influence into Saturday, highs in the 20s to lower 30s are expected.
