Expect the clouds to break up some during the day today, but even with some sunshine, much of northeast Oklahoma and far northwest Arkansas will remain below freezing today. There is some concern that parts of far northeast Oklahoma and northwest Arkansas will struggle to climb above freezing before the onset of precipitation late Tuesday, leading to some potential for light freezing rain. The valleys of northwest Arkansas will liekly be most at risk for any light freezing rain.
TEMPERATURES ARE MOSTLY IN THE LOW TO MIDDLE 20S. HIGHS THIS AFTERNOON WILL LIKELY REMAIN BELOW FREEZING ACROSS MOST OF WEST TENNESSEE. TEMPERATURES WILL TREND WARMER TUESDAY INTO MIDWEEK.

1) Freezing fog potential this morning. Have areas of freezing fog for the 6 most western forecast counties. A warm front separating the modified Arctic air from downslope warmed air will lift northward today. 3) Freezing fog for tonight. SREF probabilities are quite high from late tonight and into Tuesday morning for dense freezing fog. Forecast soundings are very conducive for freezing fog formation as warm air advection brings higher dewpoints in the region. 4) Lastly, wind chills for Tuesday morning should not be terrible as the winds are expected to be fairly light and mins should be slightly warmer with the aforementioned waa pattern.
COLD 925 MB TEMPERATURES OVER THE STATE WILL SLOWLY MODIFY A BIT UPWARD AS RIDGE AXIS SLOWLY APPROACHES FROM THE WEST.

CANCELLED FREEZING RAIN ADVISORY FOR LOWER SNAKE RIVER PLAIN AS TEMPERATURES HAVE RISEN ABOVE FREEZING.
Areas of valley freezing rain and mountain pass snow this morning, creating hazardous travel conditions. Meanwhile, valley locations have been seeing a mix of rain, freezing rain and snow. Travel this morning will be difficult at times, especially in western Montana where subsurface temperatures remain below freezing, allowing rain to freeze to paved surfaces such as roads, sidewalks and parking lots. A freezing rain advisory remains in effect through this morning. Precipitation will largely taper off by mid day today, other than some lingering snow showers in the higher terrain. A short lived ridge of high pressure will set up over the area late this afternoon through tonight.
311 AM EST MON JAN 18 2016 LARGE AND COLD UPPER LEVEL LOW CENTERED OVER NORTHEASTERN ONTARIO EARLY THIS MORNING EXPECTED TO TRACK EAST INTO UPSTATE NEW YORK TODAY. WITH TRAILING SHARP TROUGH AXIS/UPPER LEVEL ENERGY DROPPING SOUTH THROUGH THE CENTRAL GREAT LAKES TONIGHT. THIS CERTAINLY POINTS TO CARRYING THE HIGHEST POPS IN THESE LOCATIONS.
259 AM CST MON JAN 18 2016 ARCTIC HIGH PRESSURE WAS ANCHORED OVER THE MIDDLE MISSISSIPPI VALLEY AREA EARLY THIS MORNING RESULTING IN BELOW ZERO TEMPERATURES ACROSS NORTHEAST KS AND NORTHERN MISSOURI INCLUDING MUCH OF EASTERN NEBRASKA. BREEZY SOUTHEAST WINDS ARE EXPECTED TO DEVELOP TONIGHT AS LOW PRESSURE DEEPENS ACROSS THE HIGH PLAINS. THIS WILL RESULT IN MORE SEASONABLE LOWS IN THE LOW TO MID 20S ACROSS THE AREA TONIGHT. DUE TO THE PROGRESSIVE NATURE OF THE MID/UPPER TROUGH ONLY LIGHT ACCUMULATIONS ARE ANTICIPATED WITH PRECIPITATION DIMINISHING FROM WEST TO EAST EARLY TUE EVENING. HIGH PRESSURE WILL BUILD OVER THE AREA TUESDAY NIGHT ALLOWING FOR STRONG RADIATIONAL COOLING WITH MINIMUM TEMPERATURES RETURNING INTO THE TEENS ACROSS MUCH OF THE AREA.
HIGH PRESSURE BUILDS MIDWEEK WITH A MAINLY DRY FORECAST EXCEPT A SLIGHT CHANCE OF SHOWERS TOWARDS MENDOCINO COUNTY.
CLOUDY SKIES MOVE IN FROM THE WEST TODAY AS A WEAK TROUGH MOVES INTO THE SOUTHWEST REGION.
549 AM CST MON JAN 18 2016 An Arctic high pressure center was moving directly over the state of Missouri this morning, causing temperatures to fall well into the single digits. For tonight, south winds will return as high pressure shifts to the east. An increase in cloud cover will also facilitate warmer conditions with lows only falling into the 20s in southwest Missouri. This feature will approach the Ozarks Region by Tuesday, forcing a quick round of rain, snow, sleet, and freezing rain. Therefore, mostly snow and sleet are expected along and north of the Highway 54 corridor. We think the freezing rain amounts will be limited to just a glaze or a few hundredths of an inch.
1248 AM EST MON JAN 18 2016 UPPER LEVEL LOW PRESSURE WILL APPROACH FROM THE WEST TONIGHT AND CROSS THE AREA MONDAY INTO MONDAY NIGHT.
302 AM MST MON JAN 18 2016 FAIRLY QUIET WEATHER FOR THE TIME BEING AS A WEAKENING UPPER RIDGE MOVES ACROSS THE REGION TODAY. MILDER TEMPS TODAY THEN ABOUT 5-10 DEGREES COOLER FOR TUESDAY.

Skies will remain clear overnight under the very dry, bitterly cold arctic high pressure. A bitterly cold airmass continues to stream southward into central Illinois, courtesy of a 1032mb Canadian high pressure building into the central/northern Plains. High pressure will dominate the region tomorrow with very cold air sitting over the area through tomorrow night. As this high pressure ridge shifts to the east, so will the very cold air. ECMWF and Canadian are furthest south, while the GFS is little quicker and north with the track of the low. The low pressure will track from Ark into TN and with this track it should keep most of the pcpn south of the CWA through the period.
404 AM CST MON JAN 18 2016 An Arctic high pressure center was moving directly over the state of Missouri this morning, causing temperatures to fall well into the single digits. For tonight, south winds will return as high pressure shifts to the east. An increase in cloud cover will also facilitate warmer conditions with lows only falling into the 20s in southwest Missouri. This feature will approach the Ozarks Region by Tuesday, forcing a quick round of rain, snow, sleet, and freezing rain. Therefore, mostly snow and sleet are expected along and north of the Highway 54 corridor. We think the freezing rain amounts will be limited to just a glaze or a few hundredths of an inch.
Temperatures should remain above freezing at KLWS overnight but a period of a rain/snow mix will be possible for KPUW.

AN AMPLIFIED UA RIDGE TO OUR WEST WILL BE TRANSLATING TOWARDS THE REGION TODAY. MAKING FOR WARMER NIGHT /30S/. SPLIT PROGRESSIVE FLOW OVER THE CONUS THIS WEEK WILL BRING A SERIES OF SHORT WAVE TROUGHS ACROSS THE PLAINS.
MOST OF THE SNOW HAS TAPERED OFF, BUT WE COULD STILL SEE A FEW FLURRIES IN THE SKIES IN THE HIGHER TERRAIN OF NORTHEAST TENNESSEE AND SOUTHWEST VIRGINIA EARLY THIS MORNING. NORTHWEST WINDS WILL CONTINUE TO BE BREEZY IN THE HIGHER TERRAIN AS A 850MB JET MOVES ACROSS THE AREA TONIGHT AND INTO TOMORROW. WHILE WIDESPREAD WIND CHILL VALUES WILL LIKELY NOT HIT ADVISORY CRITERIA, THERE WILL DEFINITELY BE PLACES IN THE HIGHER ELEVATIONS THAT GET WELL INTO THE NEGATIVE WIND CHILL TEMPERATURES OVER THE NEXT 24 PLUS HOURS. OTHER THAN THE WINDS IN THE HIGHER TERRAIN, THE REST OF THE AREA WILL ALSO BE VERY COLD TODAY WITH HIGHS NOT REACHING ABOVE FREEZING FOR MOST PLACES.
