Aikyam-Lab/Synoptic-Bench huggingface dataset:
This low is very close in line with 00z Global Canadian, 06z HRRR and 06z NAM, which are farther north than the 00z GFS. Band of snow south of the low will move east, with 850 mb warm advection out ahead of the system focusing snow chances in the north half of the fcst area and southern Canada. After a brief period of improvement to VFR possible late Tuesday morning, IFR to MVFR conditions return with a cold front arriving during the afternoon and hours.
A cold front will move south across the forecast area today which will be mainly dry as moisture stays mainly south and west of the forecast area.
This is due to an area of high pressure slowly drifting east across the Central Gulf Coast and opening the door for milder temperatures later this week.
Noticeably cooler air has filtered into the area, but at least winds are slowly diminishing. Have lowered tonight's lows a bit toward some of the lower MOS guidance due to the nearly ideal radiational cooling setup. Some thin high clouds will spread N into the area on Wednesday, but daytime highs will average 4 to 8 degrees warmer than today's highs.
1028 AM EST Tue Feb 13 2024 Low pressure will move farther away from the Mid-Atlantic coast today. Gusty northwest winds and drier conditions are expected this afternoon into Wednesday as high pressure builds in.
(Rest of today through Wednesday) The cold front crossed the FL peninsula earlier this morning and is now along the Straits, while high pressure is building in from the deep south US. High pressure maintains control on Wednesday, although with it shifting to the SE US, our flow will become northeasterly by the afternoon.
(The rest of today) Warmer conditions remain expected today, with plenty of sun and southwesterly winds this afternoon across eastern Oklahoma and northwest and west central Arkansas. Parts of far northeast Oklahoma that saw more snow than other spots remain cooler than areas farther west, and although highs have been increased a bit using the MOS guidance consensus, this pattern has been maintained given current observations.
Closer to the Atlantic Coast and along the I-95 and US 17 corridors expecting low temps around 40F and into the lower to middle 40s at beachfront locations.
Temperatures along the island chain are currently in the lower to mid 70s with dewpoints stunted in the mid 60s. Temperatures will steadily decline into the night as cooler continental air is advected in from the north. This will allow high pressure to build in along the Eastern Seaboard tomorrow. Breezes will gradually clock around to the east as this high promotes dry and somewhat cool conditions late into this week.
133 PM EST Tue Feb 13 2024 Windy and cooler behind a system today.
MFL's sounding from this morning is similar to what we would have expected ours to have been with full saturation in the lower levels and drier air above 750 mb. This is not expected to last as northerly breezes behind the cold front will start to freshen this afternoon. The upside is that rain should be out of our area before this with near nil PoPs expected through the short term, as cooler and drier air is advected in.
Lows will be normal for this time of year, mostly in the lower 30s.
One notable addition to the forecast today is chance for freezing fog in the eastern Texas Panhandle tonight. Temperatures should also drop below freezing early this morning, causing some surfaces to become slick if fog settles in.
1053 AM CST Tue Feb 13 2024 As of 10:30 AM today, temperatures are gradually rising into the lower 50s under sunny skies. With insolation continuing as a result, temperature maximums are expected to reach the lower 60s areawide.

Pleasant conditions have continued across the region this afternoon, where most locations have so far reported highs in the lower 60s as of 1 PM CST while dew points have remained comfortably in the 30s.
NE ridges continue to see borderline advisory criteria wind gusts, so will likely hold onto the Wind Advisory in that area until expiration at 18Z. - Cooler but clear conditions are in store. Winds have gone to the WNW and are expected to prevail at any where from 15-20mph with gusts as high as 25 for the metro area and up to 35mph for the highest elevations of NW Georgia. Those winds will gradually decrease as the day goes on and high pressure builds in. High temps today will be in the low to mid 50s for most of the CWA with temps approaching freezing north of the fall line. That trend will continue tomorrow with highs in the upper 50s and lows and lows near freezing.

1104 AM EST Tue Feb 13 2024 High pressure briefly builds back into the region. Went close to guidance for high temperatures with highs in the lower 40s to around 50 degrees. Milder temps expected for Wednesday, with locations near the Tristate favorable to reach the lower to middle 50s.
1111 AM CST Tue Feb 13 2024 (Today and tonight) Temperatures will warm further today as low amplitude ridging builds in and mid-level temperatures continue to warm.
Although a few cirrus clouds may begin to spread across the region after Midnight as a low-amplitude 500-mb ridge translates eastward across the southern Plains and induces a return to westerly flow aloft, they should not inhibit otherwise favorable conditions for radiational cooling, and lows are expected to reach the u20s-l30s (perhaps a bit colder in some of the valley locations in northeast AL). A patchy-areal coverage of freezing fog is also anticipated beginning late this evening, with a heavy coating of frost expected for most of the region by sunrise.
High pressure continues to build into the region behind yesterday's cold front. While this feature will lead to pleasant conditions the rest of the week, much cooler and windy weather is in store for us today. Dry and mild conditions are expected through the end of the work week under the upper level ridge.
-------------------------------------------------------------- Strong subsidence this morning, noted in the 12Z PIT sounding has mostly clear conditions across the region (minus the ridges with upsloping). With limited moisture in the DGZ and surface temperatures recovering to above freezing by this afternoon, no significant accumulation is expected. With a tight pressure gradient, wind gusts will range from 20-25mph in the lower terrain; 30-40mph within the ridges of WV/PA.

34/JFB (Now through Wednesday) The low stratus deck from early this morning has cleared out and we are left with abundant sunshine for the afternoon.
All locations this morning are now post frontal as the cold front clears the Florida Peninsula to the south.
Layered, precipitating clouds will peel off to the east late this morning, leaving shallow/warmer and non-precipitating stratocu for a short period through the early afternoon hours. A northern stream trough and 5-6 degrees of cooling at mid and upper levels will deepen the lower clouds into the DGZ this afternoon and tonight, leading to flurries/brief snow showers over the Central Ridge and Valley Region and sctd-numerous snow showers across the NW Mtns and Laurel Highlands. Highs today will range from the mid 30s over the western and northern Alleghenies to around 40F in the south central ridge and valley region. Leaned a bit warmer for lows vs. High pressure building into the region should cause any lingering snow showers to taper off Wednesday with an increasing amount of sunshine and temperatures near seasonal normals.
The remaining snow will keep temperatures colder tonight compared to surrounding areas with lows mainly in the mid-20s and lows several degrees warmer elsewhere.
Morning cloud cover over the northern Edwards Plateau may linger into the afternoon keeping temperatures slightly cooler down there.
1112 AM CST Tue Feb 13 2024 (Today through Wednesday) The upper low is swinging through this morning, providing cloud cover to a good portion of the area through the morning.

Our southern counties are starting to see an increase in high clouds early this morning as upper level moisture starts to slowly advance north ahead of the next trough well to our south. With the low level moisture transport continuing through the day, these low clouds should linger through much of the afternoon and drift further east towards the Heartland, though they could become more scattered with daytime mixing. The cooler spots, as expected, will be across our southern zones where cloud cover will be more of a factor.
