300 AM EDT TUE OCT 11 2016 Dry and cool high pressure will dominate through midweek. A dry cold front will push through the region late in the week. High pressure will return for the weekend. High pressure will maintain its control over the eastern third of the U. today as the surface center moves into New England and the ridge extends southward east of the Appalachians. We do have some high clouds that will be passing through in the morning, but full sunshine is expected by afternoon with highs in the lower 70s north to mid 70s south. Temps may be a bit warmer as the cold advection weakens, but I still expect some mid 40s in places in the north with lower 50s in the south.
516 AM EDT Tue Oct 11 2016 High pressure will slide to the east today and Wednesday.
1117 PM MDT Mon Oct 10 2016 Current surface analysis shows cold front sinking slowly south across northeast WY and SD. Strong jet ahead of the trough will help to push the front south and east of the area tonight. Temps range from around 60 over portions of far northwest SD to the lower 80s across far southern SD. Some light accumulations of snow are likely over portions of far northwest SD, northeast WY, and the Black Hills area, mostly an inch or less, possibly a couple of inches over the higher Black Hills. Chilly temps will continue on Wednesday with high pressure settling into the nrn plains.
441 AM EDT Tue Oct 11 2016 High pressure will build across the Northeast United States to the New England coast during today, then slides into the northern Atlantic late tonight through Wednesday.
319 AM CDT Tue Oct 11 2016 Cold front through all but the Park Rapids and Wadena areas and it should be through those areas by 12z. Mid level mositure streaming northeast ahead of a positively titled 500 mb short wave trough will bring some light precipitation to northeastern ND and into far northwestern MN as the morning progresses and this precipitation area will sink south and east this aftn and evening.
a cold front associated with the trough passing to the north will push through the cwa in the 02z- 05z time frame. A weak short wave embedded in the westerly flow aloft is expected to bring clouds late Wednesday night and help keep temperatures above freezing.
135 AM EDT TUE OCT 11 2016 Dry and cool high pressure will dominate through midweek. A dry cold front will push through the region late in the week. High pressure will return for the weekend. An h5 ridge axis will also be near the area through the period. High pressure centered over the New England states will continue ridging into the region through the period. Temperatures will be in the lower to middle 70s for daytime highs with overnight lows in the middle 40s to middle 50s.
201 AM EDT Tue Oct 11 2016 A large high pressure system will maintain control of our weather through Wednesday.
649 AM EDT Tue Oct 11 2016 A southerly flow will allow a warming trend into Wednesday as a high pressure system remains over New England. Clouds will increase on Wednesday with a round of showers and perhaps a thunderstorm later Wednesday afternoon into Wednesday night, as a cold front moves through the region.
Widespread freezing temperatures will be likely early Wednesday morning.
416 AM CDT TUE OCT 11 2016 Upper level analysis places southern stream trough just off west coast while positive tilt northern stream trough advances into MT. winds were southwest with dew points ranging from the low 50s across the far southern/eastern zones to the high 30s in the northern/western zones. Today will be dry with temperatures warming into the high 80s and low 90s across the Panhandles as downsloping southwest winds become gusty in the afternoon. but latest forecast guidance suggest near neutral height tendencies and warmer air aloft leading to less CAPE (500-1000 J/kg) and minimal forcing. This is in response to northern stream trough axis as it shifts east over the Ohio Valley.
159 AM EDT TUE OCT 11 2016 High pressure keeps dry weather going through mid weak.
423 AM EDT Tue Oct 11 2016 A large high pressure system will maintain control of our weather through Wednesday.
141 AM EDT Tue Oct 11 2016 Dry weather will continue tonight through early Wednesday as high pressure moves east. A cold front traveling from the west will bring the likelihood for showers Wednesday night.
349 AM MDT Tue Oct 11 2016 Upper level analysis has strong trof swinging through the Northern Rockies at the moment. At the surface, cold front has moved south and east of the Forecast area, with high pressure building into northern Montana. Strong upper trof will shift east from the Rockies into the Great Plains. Highs will range from the upper 30s across parts of far northwest SD and northeast WY to the lower 50s over far southern SD. Upper trof axis shifts east of the area with cold Canadian high pressure over western SD Wednesday morning.
322 AM EDT Tue Oct 11 2016 High pressure over the region today will gradually shift offshore through Wednesday.
A cold front to shift southeast across the midwest on Wednesday.
353 AM CDT TUE OCT 11 2016 Skies are clear across North Texas early this morning with weak upper ridging and a dry airmass in place. Water vapor imagery shows a large upper trough moving into the northwest U. The upper trough will quickly move through the Northern Plains tonight sending a fairly strong cold front southward toward Texas during the day on Wednesday.
406 AM EDT Tue Oct 11 2016 High pressure will maintain dry weather through Wednesday.
459 AM EDT Tue Oct 11 2016 A southerly flow will allow a warming trend into Wednesday as a high pressure system remains over New England. Later Wednesday afternoon and into Wednesday night, a cold front is expected to move through with showers and a slight chance for thunderstorms.
609 AM EDT Tue Oct 11 2016 High pressure will maintain dry weather through Wednesday.
543 AM EDT Tue Oct 11 2016 High pressure over the region today will gradually shift offshore through Wednesday.
144 AM EDT Tue Oct 11 2016 Cool and dry Canadian high pressure will build over the region this week, bringing the coolest air of this early Fall season.
The upper trough that is over Iowa continues to spread cirrus clouds across the local area. As well, current dew points are a few degrees warmer than previously forecast. This has also impacted the slightly warmer low temperature forecast.
333 AM EDT Tue Oct 11 2016 Broad high pressure along the east coast continues to keep a steady northeast flow across the Florida peninsula today and into much of the week.
459 AM EDT Tue Oct 11 2016 High pressure will crest over the area today and tonight then move east of the region on Wednesday.
343 AM EDT TUE OCT 11 2016 Canadian high pressure will extend across the eastern U. Expect low temperatures generally in the low 40s with some upper 30s possible in our normally cold zones. The upper level ridge is expected to shift slightly east on Tue, with the ridge axis situated along or just offshore the Carolina coast. Meanwhile, strong (~1030 mb) high pressure over the northern Mid-Atlantic today will shift to the New England coast on Tue.
253 AM EDT Tue Oct 11 2016 High pressure will crest over the region Today providing sunny weather and light winds. The high will gradually shift east into the Gulf of Maine this afternoon through Wednesday.
Instead, expect overnight lows to range from the low 50s across southeast Alabama, to the mid 50s from Tallahassee through Valdosta, up to the upper 50s or near 60 degrees along the coast and across the southeast Big Bend. A weak, upper-level short wave trough, currently over the TX Panhandle, will translate slowly eastward, passing through our forecast area on Wednesday. At the surface, much of the eastern CONUS will be dominated by a northeast-southwest oriented ridge. A few of the CAMs forecast some shower development in north FL on Wednesday, as weak Q-G forcing (associated with the passing upper trough) combines with a moistening PBL, a less stable lower troposphere, and mesoscale convergence zones.
This narrow band of snow is forecast to further develop this morning as an upper level trough swings through the Northern Plains. Locations and amounts are always tricky when it comes to mesoscale bands, but today's forecast is especially tricky due to temperatures remaining right near the freezing threshold. Further east across central North Dakota a mix of rain and snow is expected with warmer temperatures in the upper 30s to low 40s.
While remaining dry, an increase in surface winds looks likely with slightly cooler temperatures.
635 AM EDT Tue Oct 11 2016 High pressure will crest over the region Today providing sunny weather and light winds. The high will gradually shift east into the Gulf of Maine this afternoon through Wednesday.
Winds in east Colorado have become gusty behind this trough but should not be persistent enough for critical fire weather conditions to be met. A pre-frontal trough should slip in from the north by early tomorrow morning. Temperatures might be slightly cooler behind the trough, primarily for southwest Nebraska and extreme northeast Colorado. Other than the upper 70s forecast for those areas, locations south of the KS/NE border can expect highs in the low to mid 80s. H5 trough and associated cold front will move across the CWA late Tuesday night into Wednesday morning. A dry and stable air mass will fill into the region in the wake of the cold front with zonal flow aloft. High temperatures on Wednesday will only reach the lower to middle 50s in the wake of the front with widespread low temperatures in the 30s Wednesday night.
Therefore, radiational cooling will cause temperatures in many locations to fall below freezing, and Freeze Warnings will remain in effect for Central Oregon, the John Day Basin, and the Grande Ronde Valley.
330 AM CDT TUE OCT 11 2016 The forecast area will be located in-between a broad upper-level ridge over northern Mexico and energetic zonal or weakly cyclonic flow extending from southern California to the southern Rockies. Afternoon highs should range from the middle 80s in the southwest TX Panhandle to the low 90s in the Rolling Plains. Low temps will range from the low 50s in the southwest TX Panhandle to middle 60s in the srn and ern Rolling Plains. The warmth of today will come to an abrupt end as a northern stream wave swinging across the Midwest sends a strong cold front southward through the area. Isentropic upglide will then develop above the surface ridging.
249 AM EDT Tue Oct 11 2016 A high pressure at the surface remains the dominant weather feature across the region again. Ridge will slowly shift to the east as a frontal system moves towards the area associated with generally zonal flow, so it is expected to be weak.
641 AM EDT Tue Oct 11 2016 A large high pressure system will maintain control of our weather through Wednesday.
411 AM EDT TUE OCT 11 2016 Canadian high pressure will extend across the eastern U. Continental polar high pressure will continue to extend SWWD across central NC today. Lows in the low to mid 40s W, to around 50 degrees or so E. Little change in the weather pattern will take place, with continued surface ridging lingering over the ERN U. In addition to the high clouds accompanying this feature, stratocumulus will continue to percolate beneath a still- strong subsidence inversion, though the models differ in the resultant coverage (NAM more clouds than GFS).
302 AM EDT Tue Oct 11 2016 Dry weather will continue today through Wednesday afternoon as high pressure moves east.
These SRLY winds will allow for warmer temps than seen yesterday. with the cold front over the plains dropping south towards the state.
436 AM EDT TUE OCT 11 2016 High pressure keeps dry weather going through Wednesday, with a warming trend.
318 AM CDT TUE OCT 11 2016 Warm and moister conditions return to the area at least for a short time, with a cold front approaching.
Isolated thunderstorms may develop at KGUY INVOF passing trough, but will not mention in TAF at this time due to low confidence. The strongest winds are situated east of the trough axis stretching from Elkhart, KS to Bushland, TX while lighter winds sit to the west. A strong cold front will race southward across the Panhandles Wednesday to bring as much as a 20 degree difference in high temperatures compared to Tuesday. This will give way to an approaching upper trough which will bring our next "best" chances for rain across the Panhandles.
603 AM EDT Tue Oct 11 2016 High pressure will slide to the east today and Wednesday.
356 AM CDT TUE OCT 11 2016 Stratus deck continues to quickly fill in to the south-southwest behind the advancing cold front, which is near Watertown at this time. 850 mb temps drop to around 0 degrees C over northern and western areas today, with slightly warmer air further east.
It'll bring wind and showers to the mountains with some spotty activity over the lower elevations into Tuesday evening. Then Tuesday night, it'll kick a pretty good cold front south through the plains, enough to bring in a surge of low clouds and possibly some spotty light precipitation Tuesday night into Wednesday.
Most of tonight should be dry as weak short wave ridging moves through the area. Frontogenetical forcing along the approaching cold front may bring some showers back into parts of south central WI late tonight. Medium A strong cold front will sweep through the forecast area Wednesday morning into early afternoon.
257 AM CDT TUE OCT 11 2016 Warm and dry zonal mid level flow today will serve to amplify lee trof/thermal ridging across the ern NM plains. MSLP gradient will be tightest e of said trof where sly winds around 15 mph are possible this PM. Meanwhile a mid level trof will be moving e of the nrn Rocky Mtns today with a cold front following. Wed PM s of the front temps will be just as warm as Tue if not a degree or two warmer. Thur PM it will be noticeably cooler e of the mtns with highs mostly back into 70s. Models do suggest a minor shrtwv trof to pass Late Thur PM and with 7h-5h LR's near 7 C/KM there could be a few tstms into Thur evening.
352 AM CDT Tue Oct 11 2016 As of 08z, surface cold front was approaching the James River Valley. Surface cold front exits the forecast area prior to 12Z Wednesday, but lingering mid level front could keep a chance of mainly light rain in parts of northwest Iowa/southwest Minnesota through mid morning.
400 AM EDT Tue Oct 11 2016 Canadian high pressure will shift offshore slowly today and Wednesday.
A large Pacific trough tapping cold air from the Northwest Territory. Yukon and Alaska will push a cold front south across the area tonight. Ahead of the cold front very windy conditions will exist with gusts of 45 to 55 mph over and near the east slopes of the mountains. behind the cold front strong north winds will blow across the northern Bighorn basin and eastern Johnson county.
A seasonably strong cold front is expected to pass through Wednesday. The exception will be parts of western north Texas and far southeast Oklahoma, where the cold front won't pass by until Wednesday evening.
122 AM EDT Tue Oct 11 2016 High pressure will maintain dry weather through Wednesday.
SHORT TERM (Now through Wednesday): A 500mb ridge over northwest Mexico will provide subsidence across Deep South Texas through most of the forecast period.
642 AM EDT TUE OCT 11 2016 Update/Aviation An upper air disturbance crossing the area this morning may bring a few sprinkles of rain but skies then skies should become partly cloudy this afternoon and it should be a little warmer than yesterday with highs near 70. A seasonably strong cold front will come through the area Wednesday evening with showers and a few thunderstorms. It will be even warmer tomorrow with highs in the lower to mid 70s.
This will mean effective radiational cooling and temperatures falling into the low 20s. An upper level ridge will gradually build into the midweek allowing for dry weather and warmer temperatures with associated height rises.
High pressure will remain north of the region this period, with a fairly tight pressure gradient in place. The high is expected to weaken Tomorrow, which will lessen the onshore flow, leading to more sunshine Wednesday afternoon.
637 AM EDT TUE OCT 11 2016 Dry and cool high pressure will dominate through midweek. A dry cold front will push through the region late in the week. High pressure will return for the weekend. High pressure will maintain its control over the eastern third of the U. today as the surface center moves into New England and the ridge extends southward east of the Appalachians. We do have some high clouds that will be passing through in the morning, but full sunshine is expected by afternoon with highs in the lower 70s north to mid 70s south. Temps may be a bit warmer as the cold advection weakens, but I still expect some mid 40s in places in the north with lower 50s in the south.
623 AM EDT TUE OCT 11 2016 High pressure keeps dry weather going through Wednesday, with a warming trend.
353 AM EDT Tue Oct 11 2016 A strong ridge of high pressure will continue to dominate the weather of eastern Kentucky through mid week. A high pressure ridge responsible for our recent run of dry weather will be situated just east of the Appalachians at the start of the period. A cold front will be approaching from the northwest with the aid of a progressive upper level trough.
604 AM EDT Tue Oct 11 2016 High pressure will crest over the area today and tonight then move east of the region on Wednesday.
As the upper trough approaches tonight, precip will move into the west behind the SFC cold front. Nam shows a 500 mb trough over the northern Rockies 00z Wed. This trough moves into the northern Plains 12z Wed and into the upper Great Lakes Wed night and the lower Great Lakes on Thu. In the extended, the GFS and ECMWF show a zonal flow across the upper Great Lakes 12z Fri with a trough on the west coast. Upper troughing moves into the Rockies 12z Sat and into the upper Great Lakes Sat night into 12z Sun. The trough on the west coast broadens and moves into the western U. A potent cold front will cross Lake Superior tonight into Wednesday morning, with strong cold advection behind the front expect northwest winds to gust to 30 knots over the eastern lake Wednesday afternoon.
300 AM EDT Tue Oct 11 2016 A strong ridge of high pressure will continue to dominate the weather of eastern Kentucky through mid week. The period will begin quiet and warm with high pressure in place.
124 AM EDT Tue Oct 11 2016 High pressure over the central Great Lakes will move to New England by Tuesday. The high will continue east Tuesday night and Wednesday. This will allow a cold front to cross the area Wednesday night.
319 AM EDT TUE OCT 11 2016 High pressure keeps dry weather going through mid week with a warming trend.
Snowfall accumulations in the mountains will vary from a trace on the southern sections, where temperatures were still in the lower 40s, to several inches on northern slopes where the colder air and dynamics are combining. Models are in good agreement that the precipitation will trail off to the southeast this afternoon as the trough axis pushes in from the NW.
659 AM EDT Tue Oct 11 2016 High pressure will slide to the east today and Wednesday.
/06Z TAFS/ Coastal troughing over the SE TX coast will limit overnight moisture transport over South Central TX as light drainage winds develop and maintains clear skies through this morning. Dewpoints were in the low 40s this morning but will increase to at least the low- to mid-50s overnight for the I-35 and coastal plains areas. Tuesday will be slightly warmer than today with highs reaching into the mid and upper 80s as 925mb temperatures increase with the southerly warm flow.
146 AM EDT TUE OCT 11 2016 Canadian high pressure will extend across the eastern U. Expect low temperatures generally in the low 40s with some upper 30s possible in our normally cold zones. The upper level ridge is expected to shift slightly east on Tue, with the ridge axis situated along or just offshore the Carolina coast. Meanwhile, strong (~1030 mb) high pressure over the northern Mid-Atlantic today will shift to the New England coast on Tue.
/ISSUED 1006 AM CDT SAT MAY 7 2016/ SKIES ARE SUNNY ACROSS THE FORECAST AREA THIS MORNING WITH TEMPERATURES IN THE LOW TO MID 70S. HIGH TEMPERATURES WILL AVERAGE IN THE LOWER TO MIDDLE 80S WITH LOWS MAINLY IN THE 60S.

236 PM PDT SAT MAY 7 2016 The arrival of a cold front will bring gusty winds to much of the Inland Northwest Sunday.
A WARM FRONT WILL MOVE SLOWLY NORTHWARD INTO SOUTHWEST NEBRASKA AND A COLD FRONT WILL MOVE FROM WEST TO EAST OUT OF EASTERN COLORADO AND INTO NORTHWEST KANSAS. CLOSED UPPER LEVEL LOW WILL BE OVER THE CENTRAL ROCKIES AT THE START OF THIS PERIOD. WIDE SPREAD LIFT WILL CONTINUE OVER THE AREA AHEAD OF THE CLOSED LOW SUNDAY NIGHT. AT THE SURFACE A DRY LINE WILL BE NEAR THE HIGHWAY 27 CORRIDOR. FURTHER WEST A COLD FRONT WILL MOVE INTO THE AREA. THERE WILL BE SOME INSTABILITY TO WORK WITH BETWEEN THE COLD FRONT AND THE DRY LINE. THIS MAY CAUSE ANY STORMS ALONG THE COLD FRONT TO BECOME STRONGER.
TONIGHT AND SUNDAY HIGH PRESSURE OVER THE NORTH CENTRAL GULF OF MEXICO IS EXPECTED TO SLOWLY SHIFT EASTWARD THROUGH SUNDAY. BUT FOR TONIGHT SHOULD HAVE CLEAR SKIES AND NEAR CALM WINDS UNDER THE INFLUENCE OF THIS SURFACE RIDGING. TEMPERATURES WILL CONTINUE TO CREEP BACK UP TONIGHT AND INTO SUNDAY AS OUR NORTHERLY/COOLER FLOW WILL BE CUT OFF. WE WILL SEE WINDS START TO SHIFT AROUND TO A MORE WEST TO SOUTHWEST REGIME AS THE RIDGE BEGINS TO RETREAT.
246 PM MDT SAT MAY 7 2016 THE UPPER LEVEL TROUGH WILL BE MEANDERING AROUND THE CENTRAL ROCKIES DURING THE PERIOD. UPPER LEVEL HIGH PRESSURE WILL BE CENTERED OVER EASTERN WYOMING SUNDAY NIGHT.
For Sunday, we should see another pleasant day and the return of westerly winds as a trough begins to approach the Northern Rockies. Highs will be a little cooler than today but still in the 70s for most valleys across western Montana and central Idaho.
Dewpoints remain a bit on the lower side, but we should see some modest moisture increase this afternoon. Some showers or storms will linger into the overnight hours across north central KY as a cold front moves through. Temperatures will vary widely tomorrow across the region with highs in the north topping out in the upper 60s and highs across south central KY reaching the lower 80s.
