326 PM CDT WED MAY 4 2016 A highly amplified pattern existed this afternoon of a longwave RIDGE over the western CONUS and a TROF over the eastern CONUS, leaving N- NW flow aloft for our region. Further upstream, a closed LOW was located over southwest Lower MI with a much stronger disturbance on its near western flank. The LOW is expected to drop nearly straight south into eastern KY by dawn Thursday and will carry the strong disturbance on its western flank south with it. Widespread min temps in the low-mid 40s are anticipated, with spots of upper 30s in northeast MO and the eastern Ozarks of southeast MO. Otherwise, the cooler start in the morning, slightly less diurnal CU clouds, and a very similar airmass should result in max temps very close to persistence: upper 60s to around 70F.
312 PM EDT WED MAY 4 2016 A SHARP COLD FRONT IS QUICKLY MOVING THROUGH SOUTHERN KENTUCKY AND NORTHERN MIDDLE TENNESSEE.
155 PM CDT WED MAY 4 2016 Upper ridging will continue to build east over the region today and tomorrow, resulting in warming temperatures and sunny skies. Another beautiful day expected tomorrow with highs a few degrees warmer than today due to the return of south winds.
316 PM MDT WED MAY 4 2016 THE STRONG RIDGE OF HIGH PRESSURE OVER COLORADO WILL REMAIN IN PLACE THROUGH TOMORROW. HIGH TEMPERATURES ACROSS THE PLAINS SHOULD CLIMB INTO THE LOWER 80S.
321 PM EDT WED MAY 4 2016 AFTER A WEAK DISTURBANCE BRINGS SCATTERED SHOWERS TO THE REGION THE REST OF THIS AFTERNOON AND EVENING, THE TREND WILL BE TOWARDS DRIER AND WARMER CONDITIONS THROUGH THE END OF THE WORK WEEK AS DEEP UPPER LEVEL LOW PRESSURE DROPS SOUTH OF THE NORTH COUNTRY.
STRONG HIGH PRESSURE ALOFT WILL CONTINUE TO PROVIDE DRY AND STABLE CONDITIONS. SOUTH WINDS WILL BE A BIT STRONGER THAN YESTERDAY AND TEMPERATURES WILL BE A FEW DEGREES WARMER. THE UPPER LEVEL RIDGE OVER WESTERN NORTH AMERICA WILL GRADUALLY BEGIN TO SHIFT EAST/BREAK DOWN STARTING THURSDAY. THIS WILL ALLOW A COLD FRONT TO APPROACH THE AREA FROM THE NW ON THURSDAY.
A pronounced synoptic scale ridge was entering across the Rockies today, yielding widespread clear skies. Any deep tropospheric westerly momentum across the Rockies will hold off until after the Short Term period, which means a continuation of fairly light winds given the absense of a leeside trough. Lower tropospheric temperatures will slowly rise with the approach of the upper level ridge, with highs Thursday in the 81 to 85F range for just about the entire west central, southwest, and south central Kansas region.
339 PM EDT WED MAY 4 2016 A DEEP TROUGH OF LOW PRESSURE WILL EVOLVE OVER THE EASTERN THIRD OF THE COUNTRY AND REMAIN IN PLACE THROUGH THE END OF THE WEEK. MORE UNSETTLED WEATHER CONDITIONS ARE EXPECTED LATE IN THE WORK WEEK AND THROUGH THE WEEKEND DUE TO THE CLOSE PROXIMITY OF AN UPPER LEVEL LOW PRESSURE SYSTEM. LOW PRESSURE WILL FORM OFF THE MID ATLANTIC COASTLINE TONIGHT IN RESPONSE TO AN APPROACHING UPPER LEVEL LOW PRESSURE SYSTEM OVER THE SOUTHEASTERN UNITED STATES. DETERMINISTIC MODELS AND ENSEMBLES ARE IN DECENT AGREEMENT THAT MEAN TROUGHING WILL REMAIN OVER OR NEAR NEW ENGLAND THROUGH MUCH OF THE PERIOD.
HOWEVER GENERALLY CLOUDY CONDITIONS PERSIST AS MOISUTURE STREAMS NWD AHEAD OF UPPER LOW DROPPING INTO THE SRN GREAT LAKES REGION. THE UPPER LOW LOOKS TO ENSURE UNSETTLED AND SHOWERY CONDITIONS THROUGH THE END OF THE WEEK. THE MODELS CONTINUE TO SHOW THE GREATEST PCPN RISK FOCUSED ALONG INVERTED TROUGH/DEFORMATION AXIS PIVOTING NWD INTO CENTRAL PA.
WESTERN TEXAS-CENTERED HIGH PRESSURE WILL AFFORD SKC TO A FEW CU WITH A NORTHERLY BREEZE THROUGH THE PERIOD. OTHERWISE NOT A LOT OF ISSUES WITH THE FCST THE NEXT FEW DAYS AS THE UPPER RIDGE REMAINS TRAPPED BETWEEN THE TWO ROBUST LOWS ANCHORED ON BOTH U. 41 LIGHT OFFSHORE WINDS WILL CONTINUE WITH A WEAK COLD FRONT OVER OKLAHOMA TO MOVE INTO THE COASTAL WATERS THURSDAY MORNING LEADING TO A BRIEF INCREASE IN OFFSHORE WINDS.
A TOUCH WARMER RIGHT AT THE BEACHES. THURSDAY WILL BE MUCH COOLER. HIGH PRESSURE AND DRIER COOLER AIR WILL BE MOVING INTO THE AREA FOR THURSDAY NIGHT AS AN UPPER LOW REMAINS OVER THE EASTERN US.
WATER VAPOR SHOWED UPPER RIDGE DOMINATING WEATHER OVER THE ROCKIES. THIS RIDGE WILL SHIFT OVER THE NORTHERN PLAINS WEDNESDAY/THURSDAY.
/issued 404 AM CDT WED MAY 4 2016/ (Today and Tonight) Upper ridge will build east over western Texas through tonight with a resultant northwest flow aloft over the forecast area. Mostly clear skies and dry conditions are on tap for the forecast area with afternoon highs warming into the lower 80s area-wide. Morning lows tomorrow will be in the the low to mid 50s.
HOWEVER LIGHTNING IS SHOWING UP WITH SOME OF THE STORMS FURTHER WEST NEAR AND ALONG THE APPROACHING COLD FRONT. THE COLD FRONT WILL MOVE MOVE ACROSS THE AREA TONIGHT WHILE THE UPPER LOW MOVES SOUTHEAST FROM LAKE MI INTO KY. THERE IS GOOD MODEL AGREEMENT WITH THE UPPER LOW MOVING SE OF KY ON THURSDAY. WITH THE COLD MID AND UPPER LEVEL TEMPERATURES ASSOCIATED WITH THE UPPER LOW MORE SHOWERS WILL BE POSSIBLE ON THURSDAY INTO THURSDAY NIGHT.
228 PM EDT WED MAY 4 2016 A DEEP TROUGH OF LOW PRESSURE WILL EVOLVE OVER THE EASTERN THIRD OF THE COUNTRY AND REMAIN IN PLACE THROUGH THE END OF THE WEEK. MORE UNSETTLED WEATHER CONDITIONS ARE EXPECTED LATE IN THE WORK WEEK AND THROUGH THE WEEKEND DUE TO THE CLOSE PROXIMITY OF AN UPPER LEVEL LOW PRESSURE SYSTEM.

DETERMINISTIC MODELS AND ENSEMBLES ARE IN DECENT AGREEMENT THAT MEAN TROUGHING WILL REMAIN OVER OR NEAR NEW ENGLAND THROUGH MUCH OF THE PERIOD.
419 PM MDT WED MAY 4 2016 QUIET WEATHER ACROSS THE CWA THIS AFTERNOON WILL CONTINUE THROUGH THURSDAY AS AN UPPER RIDGE DRIFTS VERY SLOWLY EAST ACROSS THE AREA. GENERALLY CLEAR SKIES ACROSS THE REGION TONIGHT AND THURSDAY THEN A FEW SHOWERS MAY POP UP OVER THE HIGHER MOUNTAINS THURSDAY AFTERNOON AS MOISTURE BEGINS TO INCREASE A BIT THERE DURING THE DAY.
200 PM PDT WED MAY 4 2016 A LOW PRESSURE SYSTEM WILL SLOWLY APPROACH FROM THE PACIFIC AND RESULT IN COOLER WEATHER THURSDAY WITH SOME DRIZZLE OR LIGHT SHOWERS POSSIBLE.
335 PM EDT WED MAY 4 2016 SHOWERS WILL SPREAD ACROSS THE AREA OVERNIGHT AS A LOW PRESSURE SYSTEM MOVES THROUGH THE REGION. TEMPERATURES WILL REMAIN IN THE LOW 40S TONIGHT.
158 PM EDT WED MAY 4 2016 COLD FRONT CONTINUES DEPARTING THE REGION ALLOWING A COOLER AND DRIER AIRMASS TO OVERSPREAD THE AREA.
1240 PM CDT WED MAY 4 2016 TRANQUIL WEATHER PATTERN WILL CONTINUE THROUGH THE PERIOD AS UPPER RIDGE DOMINATES ACROSS THE REGION.
In the wake of a cold front, some slight cold air advection has produced a cooler day today. It looks like highs should range from the mid 70s in the north, to the lower 80s in the Florida Big Bend.
234 PM CDT WED MAY 4 2016 Deep upper-level ridge over the Rockies will be the dominant weather feature for the next 2-3 days as it gradually shifts eastward into the Plains.
MORNING EVALUATION OF LATEST DATA SHOWS UNSEASONABLY STRONG UPPER LOW CENTERED OVER W GREAT LAKES. STRONG VORT MAXES ROTATING ALONG W PERIPHERY OF THE LOW. ALONG WITH AN ASSOCIATED SFC COLD FRONT. /ISSUED 421 AM EDT WED MAY 4 2016/ COLD FRONT HAS EXITED THE CWA THIS MORNING. CLOSED UPPER TROUGH WILL IMPACT THE AREA THROUGH THURSDAY. WITHIN TOLERANCE BUT ON THE LOW SIDE COMPARED TO THE NEIGHBORS AND THIS MAY BE A BIT TOO CONSERVATIVE IF THE CONVECTION DOES TAKE ON A MORE ORGANIZED LINEAR FORM. AS CLOSED TROUGH SPINS OVER THE CAROLINAS THURSDAY. 31 UPPER CLOSED LOW CIRCULATING OVER THE MID ATLANTIC STATES AT THE START OF THE PERIOD.
Temperatures will be stunted in their diurnal rise thanks to CAA behind the cold front, but with a strong sun angle and somewhat warm start to the day, should still top out in the 65 to 70 degree range. Cooler start, but slightly less clouds with more or less the same airmass should result in a day that strongly favors persistence max temps. Believe that better chances for SHRA will remain E of the area, but have kept mention of isod SHRA for early to mid this afternoon as a vort max rotates around the upper low.
HIGH PRESSURE THEN SPREADS OVER THE REGION THURSDAY.
235 PM MST WED MAY 4 2016 A SLOW MOVING LOW PRESSURE SYSTEM WILL MOVE INTO THE SOUTHWEST DURING THE REMAINDER OF THE WEEK YIELDING MUCH COOLER WEATHER.
PART OF A LARGER-SCALE UPPER TROUGH ATOP THE EASTERN CONUS. AFTERNOON TEMPERATURES SHOULD PEAK AROUND THE LOW 70FS NORTH TO MID 70FS SOUTH.
203 PM MDT WED MAY 4 2016 QUIET PERIOD WITH CLEAR SKIES AND A WARMING TREND WILL CONTINUE DURING FORECAST PERIOD AS THE UPPER RIDGE BUILDS ACROSS THE FORECAST AREA. MAIN WEATHER CHANGE AS A RESULT WILL BE A STRENGTHENING RETURN FLOW ON THE BACK SIDE OF THE HIGH TOMORROW WITH SOUTH WINDS INCREASING TO 10-20 KTS BY MIDDAY. AFTERNOON TEMPERATURES TOMORROW WILL CLIMB INTO THE LOWER 80S AS 850 MB TEMPERATURES WARM ANOTHER 3-4 C.
333 PM CDT WED MAY 4 2016 THE SHARP UPPER LEVEL HIGH PRESSURE RIDGE THAT ALREADY HAS BEEN DOMINATING OUR WEATHER TODAY WITH DRY SUBSIDENT FORCING WILL EDGE EAST TO ALONG OUR WESTERN BORDER BY LATE ON THURSDAY. THERE IS GOOD AGREEMENT IN THE MODELS THAT THIS UPPER LOW WILL MAKE SLOW AND STEADY EASTWARD PROGRESS INTO THE DESERT SOUTHWEST LATE WEEK INTO EARLY THIS WEEKEND BEFORE PORTIONS OF IT BEGIN EJECTING OUT INTO THE PLAINS.
312 PM PDT WED MAY 4 2016 AN AREA OF LOW PRESSURE OFF THE CALIFORNIA COAST WILL BRING GUSTY WINDS ONCE AGAIN TO PARTS OF THE AREA ON THURSDAY.
341 PM CDT WED MAY 4 2016 AN OMEGA BLOCKING PATTERN WILL PREVAIL OVER CONTIGUOUS U.
310 PM MDT WED MAY 4 2016 THE AXIS OF A RIDGE OF HIGH PRESSURE HAS MOVED OVERHEAD TODAY FOR WARM TEMPERATURES AND SUNNY SKIES. A FEW FLAT CUMULUS HAVE BEGUN TO DEVELOP OVER THE HIGHER TERRAIN THIS AFTERNOON. THE RIDGE WILL BEGIN TO SHIFT EAST AS THE NEXT PACIFIC LOW PRESSURE SYSTEM DROPS SOUTHWARD ALONG THE CA COAST. OVERNIGHT LOWS WILL BE WARMER THAN TONIGHT'S DUE TO THE WARM DAYTIME HIGHS. THE CHANCE FOR SHOWERS AND LATE DAY THUNDERSTORMS WILL INCREASE DURING THE WEEKEND AS THE LOW PRESSURE SYSTEM APPROACHES AND THEN PASSES OVER THE AREA.
330 PM CDT WED MAY 4 2016 A low pressure system was moving eastward across the Great Lake region this afternoon with a trailing weak cold front positioned over the Ohio River valley to Northern Arkansas to Northeast Oklahoma. Slightly cooler conditions look to continue Thursday. a couple degrees cooler than today.
930 PM EST Sat Dec 24 2016 High pressure will move east across the area tonight and then east of the local area Sunday.
615 PM EST Sat Dec 24 2016 Weak high pressure will prevail tonight.
405 PM CST Sat Dec 24 2016 Focus will be on Christmas day which will be the highest impact overall during this forecast. The high wind watch remains, and I also upgraded the fire weather watch to a Red Flag warning for our entire area tomorrow afternoon. The high wind watch will likely be upgraded to a warning tonight. Guerrero A strong cold front will pass through the area on Christmas day brining very windy conditions and a dry airmass across the forecast area on Christmas day.
743 PM EST Sat Dec 24 2016 High pressure will build over the region tonight and Christmas Day.
Varying ceilings/visibilities between LIFR to MVFR are expected to continue spreading northward across Eastern Oklahoma and Northwest Arkansas this evening and overnight in response to a warm front lifting into the CWA. /Issued 304 PM CST Sat Dec 24 2016/ A warm front, currently located just south of the Red River, continues to make steady northward progress, something that will continue overnight. The main question for tomorrow's weather remains the amount of instability that will develop across the region during the afternoon and evening hours, in advance of an approaching cold front.
A 120+ kt h250 mb jet was entering the base of the trough and by 12z Sunday the GFS moves the wind max to eastern Colorado then proceeds to wrap it around the eastern side of the closed low by 21z Sunday.
/issued 237 PM CST Sat Dec 24 2016/ A deep upper level trough has arrived over California and will move into the Four Corners region overnight pushing a Pacific cold front through the area Sunday. Strong winds on the southern periphery of the trough will mix down into the Guadalupe Mountains where a High Wind Warning is in effect. On the one hand the timing of the trough (early morning) is not favorable for daytime heating to mix elevated winds to the surface and the surface pressure gradient will only support about 20kts.
858 PM EST Sat Dec 24 2016 Satellite analysis shows and upper level low exiting North America near the Canadian Maritimes, and a deep latitudinal trough moving across the Cascades. between these tow features we have a weak trough stretched across the Tennessee River Valley and high pressure spreading eastward across the Great Lakes and eastern United States. The immense area of high pressure to our north will strengthen overnight resulting in a wind surge.
944 PM CST Sat Dec 24 2016 Have seen the latest NAM which suggests more ice/freezing rain southeast. However GFS much cooler from 18z run. Will wait for a look at the GFS 00z run going more freezing rain/sleet southeast. A 120+ kt h250 mb jet was entering the base of the trough and by 12z Sunday the GFS moves the wind max to eastern Colorado then proceeds to wrap it around the eastern side of the closed low by 21z Sunday.
A weak inverted trough will linger near the east central Florida coast into the overnight, producing surface winds out of the E/NE. Temperatures overnight will be mild, with lows in the upper 60s/around 70 along the coast south of the Cape, and in the low to mid 60s farther north and inland. (Previous Discussion) After some morning fog, another warm day is on tap with steady onshore/ESE flow coupled with strong mid level ridging aloft. Maxes will reach the lower 80s.
Otherwise tomorrow continues to look like conditions will be mostly dry as the upper level trough axis will be off to the east.
850 PM EST Sat Dec 24 2016 High pressure will build over the region tonight and Christmas Day.
The moist and cold upper level trough over the western Great Basin this afternoon will work slowly east across Utah later tonight through Sunday.
552 PM CST Sat Dec 24 2016 An approaching upper trough will induce lee-side cyclogenesis over CO/WY/NEB tonight, which in turn will cause an existing baroclinic zone near the MO/AR border to lift northward as a warm front. Between the stratus deck and the approaching warm front, temperatures won't fall very far tonight, and temperatures for many locations should remain nearly steady and/or rise after midnight. Once the warm front has lifted northeastward, temperatures will surge into the upper 50s to low 60s despite the cloud cover, and southeasterly winds will also increase with gusts reaching up to 25- 30 mph during the afternoon. There will likely be a dry period during the late afternoon before precipitation chances increase again ahead of an approaching cold front.
607 PM EST Sat Dec 24 2016 High pressure off the Mid-Atlantic Coast continues moving further into the Atlantic Basin with a weak front stalled just north of the area. The front will weaken tonight allowing a ridge of high pressure to spread across the region from the north on Christmas Day.
654 PM EST Sat Dec 24 2016 High pressure will move east across the area tonight and then east of the local area Sunday.
1017 PM EST Sat Dec 24 2016 High pressure will build over the region tonight and Christmas Day.
/22/ Tonight and Sunday, the ridge kept the front at bay with only a small section of the cwa getting any rain this afternoon. May be in the lower to mid 60s for much of the area if the clouds return sooner.
A warm front is impinging on this area from Tennessee. Conditions will be very slow to improve until the warm front passes on Christmas Day. As the warm front arrives, areas of light rain and drizzle will become more numerous. The highest rain chances will then move into southern IL and southwest IN on Christmas morning. The fog would likely stick around until the front lifts north of the region as a warm front Christmas morning.
Lowest visibilities will be along and north of Interstate 40 as a warm front sits across the forecast area but will slowly move north. Widespread rain is currently strung out north of warm front from Arkansas eastward across Tennessee into North Carolina and will move little tonight. This will keep lifr ceilings and visibilities through the overnight and well into Christmas Day before the warm front to our south pushes northward and sweeps clouds and fog out of here during the afternoon Christmas Day.

A passing cold front will arrive around 25/12Z at KDHT, 25/13Z at KAMA and 25/15Z at KGUY, bringing with it showers and maybe an isolated thunderstorm. /Issued 405 PM CST Sat Dec 24 2016/ Focus will be on Christmas day which will be the highest impact overall during this forecast. The high wind watch remains, and I also upgraded the fire weather watch to a Red Flag warning for our entire area tomorrow afternoon. The high wind watch will likely be upgraded to a warning tonight. Guerrero A strong cold front will pass through the area on Christmas day brining very windy conditions and a dry airmass across the forecast area on Christmas day.
700 PM EST Sat Dec 24 2016 Aviation An area of high pressure over Michigan will shift east tonight.
916 PM EST Sat Dec 24 2016 Weak high pressure will prevail tonight.
656 PM EST Sat Dec 24 2016 High pressure off the Mid-Atlantic Coast continues moving further into the Atlantic Basin with a weak front stalled just north of the area. The front will weaken tonight allowing a ridge of high pressure to spread across the region from the north on Christmas Day.
Therefore expect surface temperatures to be above freezing before most of the drizzle/light rain develop Sunday morning. There is a slight chance of freezing drizzle and drizzle after 3 am toward central WI.
Cold front appears to be located directly across the mid state basically bisecting the cwa from sw to ne. The boundary will become stationary and then drift northward as a warm front. Otw, forcing may increase a touch across the north as the warm front begins to lift out. We may see some partial sunshine in the afternoon as the mercury reaches into the lower 70s.
Cold front and associated precipitation is moving across the area this afternoon and will exit the area tonight.
344 PM EST Wed Feb 1 2017 Low pressure in Canada continues to send a cold front through early tonight with scattered snow showers. Then, drier and cooler air enters the region as high pressure takes control into the weekend.
304 PM CST Wed Feb 1 2017 Low and mid level clouds sagging southward behind the exiting cold front will continue to exit the area to the southeast. The high clouds expand to the northeast during the afternoon, but the dry mid levels will keep the region dry through the day.
1240 PM EST Wed Feb 1 2017 Low pressure in Canada continues to send energy through the region with scattered rain/snow. One such disturbance will be the cold front that moves through early tonight with scattered rain/snow showers. Then, drier and cooler air enters the region as high pressure takes control into the weekend.
surface arctic high pressure extended from the center over the Canadian/US Rockies in BC/Alberta/Montana with the ridge axis extending southeastward across the Dakotas. On Thursday the arctic high pressure center settles over the MT/ND border will make for a sunny but cold day with highs mainly from 5 to 15 above zero.
A weak trough of low pressure currently across central Wisconsin will drop southward later today, potentially triggering a few rain and snow showers across northeast Illinois. A secondary cold front to our north is expected to shift through the northern counties later this afternoon and the rest of the forecast area overnight. and high pressure building over the northern Plains and into the Midwest.
239 PM CST Wed Feb 1 2017 A cold front positioned just to the north of the Interstate 40 (I-40) corridor continues to make very slow progress south.
Models in decent agreement in depicting a lull in the heavier snow overnight into Thursday morning but there will be some areas of fog and maybe even a bit of freezing drizzle though very cold temperatures should hinder the freezing drizzle overnight. especially near and north of the Pine Ridge.
In the wake of the passing cold front, current observations shows overcast skies hanging tough across parts of SW Kansas and SE Colorado.
Farther north, was more optimistic, except in the low spot CXO.
A weak cold front will push south, across West Central Texas, during the next 6 to 12 hours. Southwest winds this morning will turn to the northwest, then north as a cold front moves through the area today. /issued 349 AM CST Wed Feb 1 2017/ (Today and Tonight) A cold front will drop south across the area during the next 24 hours. Cooler temperatures for tonight with lows mainly in the 30s. A cold front drops south of the area by Thursday morning.
Soundings slightly warmer in western portions of Kit Carson and Cheyenne counties in Colorado, which might see the best potential for freezing precipitation. The overall H5/H7 flow over the Central Plains from the latest runs of the GFS/ECMWF does favor mainly zonal flow with some ridging building over the area towards the latter half of the weekend.
Today: Fog has yet to develop as of forecast package issuance, however guidance is still showing axis of fog developing along front and a smaller area of dense fog possibly freezing drizzle near the frontal zone. I decided not to change freezing fog/drizzle, but could see needing to increase coverage if we can get a better handle on evolution (once it gets underway). At least early on this evening/tonight soundings support primarily freezing drizzle/fog development. Depth of saturated layer increases enough by 06Z that it could be argued that freezing rain would be favored over drizzle, however messaging/impacts are effectively the same based on the projected amounts. Regarding amounts/impacts: If freezing drizzle (or light freezing rain) were predominate we would be looking at 0. Freezing drizzle is possible further east in our CWA, but coverage and amounts would be even less (trace).
The mean upper trough over eastern North America will be reinforced later this week and bring a return of below normal temperatures for a change.
257 PM CST Wed Feb 1 2017 Unseasonably mild and breezy weather today over sern TX ahead of weak low pressure center over n-central TX and associated cold front pushing swd across west TX early this afternoon. Tomorrow's forecast remains a bit tricky as the cold front over west TX pushes sewd into the area during the day.
202 PM CST Wed Feb 1 2017 Colder cyclonic flow in place across the area today following a rather wild cold frontal passage with vigorous snow showers yesterday afternoon/overnight. High pressure remains in control through Thursday night for quiet/cold conditions.
259 PM CST Wed Feb 1 2017 Cold front has passed through a good chunk of eastern Oklahoma and northwest Arkansas but is currently hung up in the higher terrain of southeast Oklahoma and west central Arkansas.
252 PM CST Wed Feb 1 2017 Subtle ridging in the mean mid level flow will lead to tranquil weather conditions for the next 24 hours.
247 PM CST Wed Feb 1 2017 A trough of low pressure extending from Michigan into north-central Illinois is triggering a few rain/snow showers in the Chicago area this afternoon. High pressure will ensure mostly sunny and cool conditions on Thursday, with highs only reaching the upper 20s and lower 30s. Trough over southern Canada seen rotating southeast toward Great Lakes. This system will push surface shot of cold air into the plains, with the associated cold high pressure to influence weather for IL through the rest of workweek. High pressure to move east of area by Sat. Significant trough off west coast today, will be producing series of upper waves moving through rockies, with first reaching central plains on Sat.
