Currently, clear skies are residing through the area, however, cloud cover is forecast to gradually increase overnight as high pressure moves eastward. This next system by daybreak Monday (our time) should become an upper level low in a deep eastward moving trough.
A cold front extending from a Nor'easter affecting New England finally pushed through the Florida Keys island chain and adjacent coastal waters late this afternoon and early evening. As the area of low pressure continues to depart the East Coast and high pressure builds across the Tennessee Valley, winds should freshen overnight. From synopsis, breezes will shift rapidly around the compass during the next five days across the Keys coastal waters, as a series of low pressure systems and associated fronts slide east through the Gulf of Mexico.
Hi-res models show gusty winds moving in with the snow, especially on Tuesday, as a cold front passes through the region.
The low will deepen and produce an expansive tight pressure gradient.
Pattern Synopsis/Forecast: Mid-level ridge axis sits just upstream early this morning, which will amplify and cross northern MI today. This occurring in advance of well-advertised deep troughing trekking over the Plains. Otherwise, continued cloudiness with temperatures topping out in the low-mid 30s.
Current readings range from the single digits to 20s in the mountains, to the upper 20s and 30s (except locally in the lower to mid 40s where north wind lingers) across the Central Valley and foothills. The higher elevations of the northern mountains may see some flurries as a weak warm front brushes the area ahead of the approaching ridge. A weakening cold front will then bring a quick shot of precipitation on Tuesday as it quickly moves southward.
High pressure persists over the eastern US today, before pushing offshore into the western Atlantic overnight ahead of a strong system forecast to affect east central Florida tomorrow. Tonight, easterly winds begin to increase and veer southeasterly, ahead of the approaching cold front. Poor boating conditions today becoming hazardous this afternoon and dangerous tonight, as winds increase ahead of an approaching cold front. An approaching cold front will increase low-level cloud cover tonight, with MVFR CIGs possibly by around 12Z for northern terminals (LEE/DAB).
A Winter Storm Warning is in effect for areas west of the Illinois River Valley were the higher snowfall amount are most likely to occur.
Snow showers will end this morning over Apache County as a low pressure system moves to the east.
Very cold air is settling into the desert southwest in the wake of yesterdayâs cold front. Morning low temperatures will fall to near or below freezing across the majority of the region for the first half of the week.
The frontal boundary to our south will lift north over the area as a warm front today, with scattered showers and a few thunderstorms possible during the afternoon hours and gradually warming temperatures. Breezy and gusty easterly to southeasterly winds are expected to develop today as the pressure gradient tightens between high pressure off the NE coast and a potent low pressure system moving across Eastern U. The associated cold front will move through our region tomorrow; Tuesday afternoon and evening. Then, winds will begin to decrease around mid week once the front pushes away from the area and a drier high pressure settles back over the area bringing cooler temperatures and drier days.
251 AM MST Mon Jan 8 2024 Very cold air is settling into the desert southwest in the wake of yesterdayâs cold front. Morning low temperatures will fall to near or below freezing across the majority of the region for the first half of the week.
Otherwise, this afternoon temperatures will struggle to warm out of the mid/upper 50s (mid 40s in the higher peaks). As such, warmer conditions are expected across the North Bay and greater Bay Area tonight. A Frost Advisory in now in effect for interior Monterey and San Benito counties Tuesday morning as temperatures are expected to cool into the upper 20s in the highest peaks to mid 30s elsewhere.
A Winter Storm Warning is in effect for areas west of the Illinois River Valley where the higher snowfall amount are most likely to occur.
546 AM CST Mon Jan 8 2024 (Monday through Tuesday) The very active short-term should kick off right on queue this morning, as the closed low over the TX Panhandle is beginning to pivot east. The pressure gradient both in front of, and behind this low remains very tight, with sustained winds both today and tomorrow likely to exceed 20+ MPH. It also still looks like a narrow window for winter precipitation exists in our north zones tonight, but temperatures will quickly jump above freezing right after this window opens. /44/ (Tuesday Night through Monday) By Tuesday night, we should see clearing skies and diminishing winds, as high pressure settles over the region.
Mostly cloudy, cool and dry conditions prevail along the Florida Keys on this early Monday morning, with temperatures in the mid to upper 60s, dewpoints in the lower 60s, and winds on land from the northeast at 10 to 15 mph.
Sub-freezing temperatures as low as 27 degrees will occur in the San Joaquin Valley this morning, as well as tonight and Tuesday morning.
Clipper system moves through the area on Tuesday with a downslope warm front bringing a brief warmup along with the initial band of snow.
Chilly temperatures this morning with lows verifying in the low to mid 30s across much of the inland regions, with the interior Monterey and San Benito Counties reporting lows in the upper 20s, and coastal regions rising to the low to mid 40s. Otherwise, this afternoon temperatures will struggle to warm out of the mid/upper 50s (mid 40s in the higher peaks). As such, warmer conditions are expected across the North Bay and greater Bay Area tonight. A Frost Advisory in now in effect for interior Monterey and San Benito counties Tuesday morning as temperatures are expected to cool into the upper 20s in the highest peaks to mid 30s elsewhere.
Expansive high pressure across the East Coast and a strong low over the Southern Plains have led to a tightening pressure gradient across the region. This is in response to a deepening low pressure system moving across the Southern Plains. This low and its attributes will be responsible for our sensible weather over the next 24-36 hrs. Low temperatures overnight are expected to only a drop a few degrees into the lower 70s. Winds will continue to clock around to the south on Tuesday, which will help temperatures break into the lower 80s across the island chain. The aforementioned low pressure system will drag it's associated frontal boundary across the Florida Keys tomorrow night, with another decaying squall line expected ahead of it.
An upper level low will track to our north this afternoon, then head toward Arkansas/Missouri Tuesday morning. Overnight lows will be in the low 30s, and these temperatures combined with the breezy conditions will result wind chill values in the upper teens to lower 20s by daybreak. Highs on Tuesday will continue to be below seasonal normals, in the low to mid 50s.
Sub-freezing temperatures as low as 28 degrees will occur in the San Joaquin Valley tonight into Tuesday morning.
NBM and MOS both showing potential for high wind speeds north and northeast of Lubbock through the evening hours in the wake of the Canadian cold front moving southeastward through the region. Have issued a Winter Weather Advisory for those two counties into early evening to account for accumulation on area roadways pending further cooling behind the Canadian cold front.
(Tonight) Dry low levels continues to thwart precipitation as upper level diffluence increases over the lower MS and TN valleys. Gusts of 40-50 mph are likely to occur, especially in the higher elevations. A few of the highest Plateau elevations in northeast AL and Franklin County TN could reach 55 mph. The progressive nature of the cold front should push the heaviest precipitation out of our central and western counties before daybreak.
Speaking of, let's hit the high notes of this system: Key point #1: **WIND** Starting tonight, sustained winds will be anywhere from 20-30 mph with gusts between 35-45 mph. The timeframe for the highest winds will be overnight tonight. Key point #3: **SNOW** As the low spins out of our area off to the NE Tuesday afternoon, cooler air will filter in and moisture will wrap around the low, helping to pump out some snowflakes.
CAM guidance eventually breaks up the precipitation into showers by late afternoon (behind the cold front) with wind speeds dropping off quite a bit.
A cold front is oriented from Texas County, Oklahoma through Randall County, Texas, and advancing southeast. The surface pressure gradient is tightening behind the cold front with blizzard conditions being observed in the northwestern combined Panhandles. Winds will continue to strengthen through the afternoon, and as the low-level jet strengthens over the Panhandles, gusts will increase. As the low moves off to the east tonight, the pressure gradient will loosen some but will remain tight enough for sustained winds to stay around 30-40 mph through much of the night in the eastern combined Panhandles.
Precipitation will come to an end from northwest to southeast during Tuesday night with our next shot of cooler drier air for midweek. The line of thunderstorms will move across the waters Tuesday afternoon and evening, then dry high pressure will build back in with winds and seas gradually diminishing through midweek.
516 PM MST Mon Jan 8 2024 Evening Update: With high temperatures well below the forecast high earlier today, the low temperatures have been adjusted for tonight. Clipper system moves through the area on Tuesday with a downslope warm front bringing a brief warmup along with the initial band of snow.
- Unseasonably cool on Tuesday with breezy conditions across the higher terrain. Current water vapor imagery and upper air analysis indicates the strong upper low continuing to move east southeast across western Texas and Central Oklahoma, with regional radars indicating showers diminishing across southeast Colorado attm. Will keep the high wind warning in place through 5 pm, as winds are still gusting to around 55 mph here at PUB. With clearing skies and diminishing winds and some snow cover, will see cold temperatures overnight with lows in the single digits and teens across the plains and in the single digits above and below zero across the higher terrain, and in the teens below zero across the San Luis Valley. Otherwise, temperature will be below seasonal levels in the 30s across the plains, and mainly in the 20s across the higher terrain.
Overnight lows were also adjusted slightly warmer as current temperatures will likely hold steady or begin rising over the next few hours.
A closed upper low will continue to move east across Kansas overnight and into tomorrow morning.
As the mid level trough axis and very cold air aloft swing across the area, there will be an increase in stratocumulus development, and a few sprinkles or even flurries can't be ruled out mainly during the afternoon to early evening over northern portions of the forecast area. Temperatures will remain above freezing at the surface however and no impacts are expected.
553 PM CST Mon Jan 8 2024 (Tonight) Dry low levels continues to thwart precipitation as upper level diffluence increases over the lower MS and TN valleys. Gusts of 40-50 mph are likely to occur, especially in the higher elevations. A few of the highest Plateau elevations in northeast AL and Franklin County TN could reach 55 mph. The progressive nature of the cold front should push the heaviest precipitation out of our central and western counties before daybreak.
817 PM EST Mon Jan 8 2024 The overall forecast remains on track this evening, with increasing winds and moisture ahead of a strong cold front for Tuesday afternoon/evening. Outside of that, windy conditions will prevail, along with warmer and more humid air. Southeast winds will continue to increase tonight ahead of a strong cold front and a Gale Warning remains in effect for all zones through Tuesday.
Current surface analysis places a warm front draped across the Gulf Coast, extending southeastward to the Straits of Florida. This warm front continues to advance northward, with a veering wind profile sampled in the 00z evening sounding at KEY. From synopsis, breezes will shift rapidly around the compass during the next five days across the Keys coastal waters, as a series of low pressure systems and associated fronts slide east through the Gulf of Mexico. The next cold front will push through the Keys waters Tuesday night, followed by brief slackening of northerly breezes. Breezes will freshen once again late this week, while veering from the east to south ahead of yet another low pressure system and cold front.
The winds and our associated hazards should diminish gradually after sunset as diurnal mixing relaxes and the strong mid level jet associated with the large upper low swings east. Very dry air and cooler temperatures have moved in behind this morning's Pacific Front and the dry and windy conditions have resulted in critical fire weather conditions, especially south of the Pecos River. Low temperatures plummet to the teens and low 20s across the region though some lingering winds factoring in will lead to wind chills in the low teens for most and even single digits or near 0 degrees in the higher elevations. Be sure to bundle up in multiple layers and cover as much exposed skin as you can! Tomorrow will be a much quieter day with much lighter winds and high temperatures a tad warmer than we're seeing today.
