THE NAM SHOWS VERY LITTLE ELEVATED CAPE WITH THE LEAD WAVE OR WARM FRONT FCST TO LIFT THROUGH THE CNTL NEB TODAY BUT K INDICES ARE 30 TO 35C IN ALL MODELS WHICH SUGGESTS THE POTENTIAL FOR AN ISOLATED THUNDERSTORMS EMBEDDED. THE NEGATIVELY TILTED UPPER TROUGH WILL ADVANCE NORTHEAST OF THE FORECAST AREA FRIDAY AFTERNOON AND PULL THE PRECIPITATION SHIELD NORTH. TRANSITORYRIDGING WILL BUILD ACROSS THE NORTHERN ROCKIES AND PLAINS THISWEEKEND AS THE UPPER TROUGH AND A SECONDARY DISTURBANCE CROSSES THEGREAT LAKES.
NEXT IN A SERIES OF COASTAL TROUGHS WILL MOVE INLAND ACROSS NE FL TODAY PRODUCING SCATTERED MORNING SHOWERS ALONG THE COAST AND ISOLATED AFTERNOON SHOWERS INLAND.

The synoptic pattern early this morning features weak ridging across the Ohio Valley, with a cutoff low across the southern Plains. This upper low will open into an open wave through the period and lift northeast, amplifying a ridge across the Ohio Valley in response. Low-level thicknesses will actually be on the increase today as ridging amplifies over the Ohio Valley, thus expect temperatures a couple of degrees warmer than yesterday which puts readings in the upper 70s to low 80s. Ridging will amplify further on Friday as the open wave ejects out into the northern Plains. Therefore, expect readings similar if not a degree or two cooler than today, with highs in the mid 70s to low 80s.
A LOW PRESSURE SYSTEM WILL MAINTAIN UNSETTLED CONDITIONS ACROSS THE REGION THROUGH TODAY.
THE DAY AHEAD WILL BE QUITE PLEASANT WITH HIGH PRESSURE OVERHEAD.

THESE HIGHER LEVEL CLOUDS SHOULD KEEP OVERNIGHT LOWS A BIT WARMER THAN THEY WERE THIS MORNING.
A few light showers are possible mainly across eastern KS and far northwest MO this morning as a weak lobe of upper- level low pressure surges across those areas; otherwise, most even low-end chances of precipitation will hold off until the late afternoon or evening hours. Strong isentropic lift ahead of the system's cold front will support a broad region of showers and embedded, isolated storms tonight through Friday, producing a widespread, much-needed potentially half to three quarters of an inch of rainfall. Whether or not a round of surface-based convection can develop along the cold front on Friday evening remains in question, and will bring our only real potential for strong to severe storms with this system.

A WEAK COLD FRONT WILL PASS THROUGH THE AREA THIS EVENING. HIGH PRESSURE WILL BUILD OVER THE REGION FRI AND SAT.
The local region will continue to reside on the east side of the upper ridge axis with subsidence drying aloft.
A weak cold front will pass through the area tonight resulting in subtle cooling for Thursday but little chance of precipitation. These temperatures will be slightly warmer than normal for this time of year. A cold front continues to crawl across the Cascades with an abundance of mid and high level moisture streaming across the region. /sb 06z TAFS: A cold front passing through the region will bring a solid deck of mid and high clouds with ceilings generally above 10K ft AGL.
remained under northwesterly flow aloft with the mid-level trough stretching across the Great Lakes region. At the surface, high pressure was spilling southward across the CWA with mostly sunny skies across northeast Kansas. As a result, have trended much cooler than the models for low temperatures tonight in northeast Kansas with readings expected to plunge into the -1 to -7 degree range, and cannot entirely rule out of the possibility of these readings not being cold enough in the far northeast corner where the best snowpack exists. At this time have lows in the low/mid single digits. As a result, expect warmer conditions for Monday with highs ranging from around 20 to around 30 from northeast to southwest.
The high shifts east across the Ohio valley tonight, as the cold air plunges across the FA. During the day tmrw, the high shifts east. 12z model runs suggest a slightly slower/slightly warmer trend than previous. With 06z-12z bulk pcpn onset, surface temps will be sub freezing across the north. Profile support light snow or sleet there, with light freezing rain or sleet further south. As the warm air noses in aloft in the 12z-18z frame, we should see a shift from snow/sleet to freezing rain or even rain, with surface temps warming to nr/above 32F. Will stick with a gradual transition to warmer pcpn types thru the morning and into the pm hours as it shifts east.
1129 AM CST SUN JAN 17 2016 ARCTIC COLD FRONT IS PUSHING INTO NORTHEAST ARKANSAS AND THE MISSOURI BOOTHEEL AT THIS TIME. BUT MOST OF THE REGION SHOULD WARM INTO THE LOW TO MIDDLE 40S.

AS THE TROUGH PUSHES SOUTH THROUGH THE DAY COOLER AND DRIER AIR WILL BE USHERED INTO THE FORECAST AREA BY NORTHWESTERLY WINDS AT THE SURFACE AND IN THE LOW LEVELS.
343 PM CST SUN JAN 17 2016 HIGH PRESSURE WILL SETTLE OVER THE AREA AND REMAIN IN PLACE THROUGH THE BEGINNING OF THE WORK WEEK WITH DRY CONDITIONS AND BELOW NORMAL TEMPERATURES.

A WARM FRONT WILL BEGIN TO MOVE NORTHEAST FROM KANSAS AND NORTHEAST COLORADO MONDAY.
LIGHT FREEZING RAIN TONIGHT FOR LOW ELEVATIONS OF WEST CENTRAL A mix of snow and freezing rain will move over the Northern Rockies this evening through Monday morning. Despite some low elevations warming well above freezing today, the ground in most areas will remain below freezing and allow rain to freeze upon contact. The freezing rain will be quite variable from moment to moment, with sudden freezing of roadways will little or no prior evidence.
HIGHS TODAY WILL BE MUCH COOLER. WARMING TREND CONTINUES MONDAY WITH HIGHS MORE IN THE LOW TO MID 60S.
MOST LOCATIONS ACROSS SW VA AND NE TN ONLY SAW A DUSTING BUT THERE WERE A COUPLE OF REPORTS OF AN INCH ACROSS THE HIGH TERRAIN ALONG THE TN/NC LINE.
