Any accumulating snow should stay confined to the higher mtns. Dry and mild for Thursday as upper ridging shifts into the region. Not many forecast concerns during this time frame due to a broad ridge axis aloft along the spine of the Rocky Mountains.
A warming and drying trend is forecast through Thursday as high pressure builds over the region and light offshore flow develops.
325 AM CDT Wed Oct 19 2016 It was partly cloudy and mild across the Mid-State early this morning, with temperatures mainly in the lower and middle 60s. As a pre-frontal low level thickness ridge builds across the state, we should see a sufficient increase to, perhaps, send temperatures a degree or so higher than yesterday's readings. The high forecast at Nashville is 88 degrees. The warm weather will be eclipsed by the passage of a cold front on Thursday and Thursday evening, and have gone with a movement that is a blend of the GFS and the slightly slower NAM.
A broad trough will remain over the area today. Flow aloft will turn to the northwest this morning as the trough axis moves to the east and an upper ridge moves into the Pacific NW. Skies will clear late this afternoon or tonight as the wave and warm front moves to the east. Upper ridge builds into Montana tonight and Thursday morning with dry and warmer weather.
136 AM EDT Wed Oct 19 2016 High pressure will remain just offshore through Thursday, bringing warm and dry conditions to the local area.
501 AM EDT Wed Oct 19 2016 A cold front will continue to move southward through the area this morning before stalling out in Kentucky. An area of low pressure will move along the front tonight into Thursday.
442 AM EDT Wed Oct 19 2016 Weak high pressure will bridge across the area today into tonight with variable clouds and continued mild temperatures.
148 AM EDT Wed Oct 19 2016 A cold front will drop southeast into Ohio tonight, bringing an increasing chance for showers and thunderstorms.
A stalled surface front extending from south- central Oklahoma to far southern Missouri, will move little today, before plunging southward tonight as the upper trough intensifies and moves across the region. Cold air advection will occur tonight into Thursday in association with the deepening upper trough.
As it moves east tonight the upper trough is expected to deepen. A few mid clouds could produce a sprinkle near Hays, with the upper trough, but should be dry enough for only virga. Highs today will range from the upper 60s west of Dodge City to the low to mid 70s east.
102 AM EDT WED OCT 19 2016 A cold front across SE Lower Michigan will move across the forecast area tonight then stall near the Ohio river tomorrow.
Early this morning a cold front was parallel to and north of the Ohio River from central Ohio to southern Illinois. Wet bulb zero heights will be on the high side for any significant hail. On Thursday the wave will head off to the northeast and drag the cold front through the region ahead of the approaching upper trof. However, there looks to still be a gusty wind threat with a continued layer of dry air aloft and stronger winds aloft as the trof approaches. Temperatures will be tricky once again on Thursday with the passage of the cold front.
Clouds and the passage of the weak cold front will keep Thursday temperatures slightly cooler. Upper level ridging will build in and persist through the weekend.
355 AM PDT WED OCT 19 2016 A ridge of high pressure will usher in a warm and dry trend today and continue through at least the first part of the weekend. some patchy valley fog may be possible with dew points running in the low to mid 40s.
350 AM CDT Wed Oct 19 2016 An upper level ridge has expanded across the entire Gulf coast to the western Atlantic. Dewpoints have been slowly increasing, now in the lower to mid 70s. Temperatures will continue to be unusually hot with high pressure in place, so have kept forecast highs in the mid to upper 80s for the next couple days. Models are still showing the next significant weather impact to be a cold front marching through the area Thursday afternoon and through the overnight period.

The warm weather will be eclipsed by the passage of a cold front on Thursday and Thursday evening, and have gone with a movement that is a blend of the GFS and the slightly slower NAM.
With relatively cold column in place most if not all the area will see temperatures below freezing.
648 AM EDT Wed Oct 19 2016 Cooler conditions will be in store for the remainder of the overnight hours behind a cool front. The front had moved south to near the Ohio River, but will begin to move back north later today and tonight as an upper level trof approaches the area.
345 AM CDT WED OCT 19 2016 Late night sfc analysis shows high pressure lingering over the sern CONUS. Water vapor imagery shows ridging aloft extending from the wrn Gulf states across the sern CONUS. Expect a few showers or storms to linger into tonight, especially over our nwrn areas where the influence of the approaching cold front will begin to be felt. likely entering the nwrn zones after daybreak/reaching the US 165 corridor around lunchtime/moving off the lower Acadiana coast late in the afternoon.
High temperatures today will range from the lower 80s coast to the mid/upper 80s inland. High pressure wedge over the region continues to weaken as cold front approaches from the NW.
130 AM EDT Wed Oct 19 2016 Rain shower chances are in the forecast tonight as a weak cold front crosses the area. That said, a decent moisture slug generally from 700 mb downward along with modest baroclinicity in the lower half of the troposphere should allow for the development and propagation of showers along the front as it translates southeastward through the night. Upper level forcing never does manage to sag southeastward overnight with this low-level boundary.
501 AM EDT Wed Oct 19 2016 High pressure will build across the region today and tonight. The high will move east on Thursday.
A strong west/southwest upper jet across Wisconsin becomes a little more southwest as an upper trough begins to dig across the northern and central plains.
222 AM EDT Wed Oct 19 2016 High pressure will build across the region today and tonight. The high will move east on Thursday.
624 AM EDT Wed Oct 19 2016 High pressure will build across the region today and tonight. The high will move east on Thursday.
Drier conditions today as an upper ridge builds across the inland NW. Southwest flow builds on Thursday as the ridge axis shifts east of the area. Temperatures warm each day, though valley warming will lag the mountains as warming aloft is slower to reach the lower elevations.
210 AM CDT Wed Oct 19 2016 Another day of near record to record high temperatures are expected by this afternoon across west Texas and southeast New Mexico in zonal flow ahead of the next cold front. This front is expected to push through the forecast area tonight as an upper level trough across the Rockies moves onto the Plains.
241 AM CDT Wed Oct 19 2016 The cold front has entered our far northern counties and will continue to slowly sink south thru sunrise. There remains a strong signal for a sfc wave of low pressure to develop and move northeast along the front into the evening hrs. The upper level trough will push through on Thursday, with precipitation tapering off from west to east thru the day, with some lingering potential in our eastern counties thru the evening hrs. Cooler air continues funneling in for Thursday night, with lows dropping well into the 40s.
Weak high pressure aloft will move east of the area this afternoon, allowing a low pressure system to approach from the west.
A broad mid- level trough of low pressure covers all but the southeast third of the U. At the surface, a cold front had advanced southward across South Dakota and Minnesota with an expansive area of stratus across the Northern Plains. The trough moves across the forecast area today with a couple of waves of energy as it moves through. The cold front pushes into northern Missouri with winds turning to the north. Tonight additional sprinkles/light showers may affect parts of the area and then Thursday, some energy on the back side of the trough could produce a few more showers.
with the low cigs eventually lifting/returning to VFR by midday. A sct cu field is expected through the afternoon once the low cigs lift. with additional isolated/sct convection developing by late afternoon over SE OK near a cold front.
A cold front is over then Northern plains, moving into northeast Wyoming and approaching southern South Dakota. By Thursday the trough will be east, and subsidence ahead of building ridge in the west will overspread our CWA. Regarding temperatures: The cold front in the northern plains should pass over our CWA this morning and Canadian high pressure will slide out of the Rockies towards the Central High Plains tonight, then eastward through Thursday night.
A frontal boundary will stall over the Ohio Valley today, before an approaching upper level trough develops low pressure along the boundary late today into tonight, which will then move along the front bringing showers and storms to the area.
A cold frontal boundary will remain draped across the region through early Thursday.
240 AM EDT WED OCT 19 2016 A deep ridge of high pressure will extend across the region through Thursday.
322 AM EDT WED OCT 19 2016 A deep ridge of high pressure will extend across the region through Thursday.
we will remain in a quiet weather pattern through the TAF period with a ridge of high pressure in control.
323 AM EDT Wed Oct 19 2016 Expect a warm day today with clearing skies as high pressure builds in from the west.
Mesoanalysis showing Lower level CAA pattern over the northern portion of the cwa in the wake of the cold front. and will trend a degree cooler most areas. Expect fairly rapid clearing in the evening with light winds as the high drops southeast into the area. Went a degree cooler than guidance overnight as well.
648 AM EDT Wed Oct 19 2016 Weak high pressure will bridge across the area today into tonight with variable clouds and continued mild temperatures.
1112 PM MDT Tue Oct 18 2016 Current surface analysis shows a nearly stationary cold front across northern MN, ND, and northern MT. Weak high pressure is centered to the southwest of the area. With clouds and pcpn around, temps will be cooler than today, with highs mostly in the 50s, some 40s over portions of northeast WY and the Black Hills. A little snow could mix in with rain over some areas Wednesday night before pcpn ends, especially over the Black Hills and the Pine Ridge.
Mid level clouds have developed across north central Alabama on the north side of a low level ridge. Weaker winds within the ridge axis have allowed stratus and fog to form over southeast Alabama. Despite decent low level lapse rates, drier and warmer air above 700mb should limit thunderstorm potential. Dry conditions overnight as the low level ridge dominates, with fog possible again across the southern counties. Longwave trough digs into the Southeast on Thursday pushing a cold front through Central Alabama.
208 AM EDT Wed Oct 19 2016 Cooler conditions will be in store for the remainder of the overnight hours behind a cool front. Lows tonight will drop into the 50s as cooler air begins to filter in. Cooler, but still above normal temperatures expected Wednesday with highs in the middle 60s to lower 70s as morning sunshine allows for a nice recovery. Longwave trough will continue to deepen and dig into the Great Lakes into Thursday with low pressure on schedule to develop and move across the Ohio Valley.
or to points north and west along a weak cold front.
Increased southerly flow in the lower levels will allow moisture from the Gulf to continue to advect in the lower levels tonight. This will result in some low clouds and warmer than average overnight lows. At least one more day of well above average temperatures is expected tomorrow before a cold front moves through on Thursday.
522 AM EDT Wed Oct 19 2016 Cooler conditions will be in store for the remainder of the overnight hours behind a cool front. The front had moved south to near the Ohio River, but will begin to move back north later today and tonight as an upper level trof approaches the area.
Temperatures ranged from the lower 50s in the north to the mid 60s in the south. A brush with cooler air late this week then warming to slightly above normal temperatures this weekend. As this trough deepens and moves towards the Appalachians, cooler air will advect in from the northwest across the upper Midwest. Some mid-level moisture associated with the upper low combined with a decent diurnal heating should lead to scattered showers/sprinkles Thursday in northern Minnesota, mainly north of the Iron Range. Highs in the low to mid 40s - just barely on the cool side since normal highs are 49/50 (INL/DLH). lows falling to the mid 20s to near 30s, warmer along the Lake Superior shoreline.
Showers have ended, though low cloud cover has pushed further into the area than previously thought as cooler airmass pushes in. A cold front continues to slowly slide southeast across North Dakota today. An upper level ridge moves in by the weekend. This in the wake of a slowly advancing cold front.
335 AM CDT Wed Oct 19 2016 At 3 AM, a Canadian cold front was located across central Minnesota. While there are some questions on the low clouds, it is pretty clear from the water vapor and infrared imagery that we will likely see a broken deck of mid and high clouds move into the area this morning and then linger across areas south of Interstate 94 through this evening. These clouds are associated with a short wave trough moving east southeast across South Dakota. On Thursday night, the models continue to suggest that the ridge of high pressure will be overhead.
High pressure at the surface and aloft will lead to another warm and sunny day across the region after some early morning fog dissipates.
The upper level flow is at present northwesterly as a ridge of high pressure moves into area throughout the day into this evening. But the shower activity should steadily decrease throughout the day as the ridge moves through. The ridge will be short lived as a strong jet streak pushes into the Pacific Northwest with an ample supply of moisture. This system will be warmer than previous disturbance, so the snow levels should rise to around 8000 feet by Thursday afternoon.
655 AM EDT Wed Oct 19 2016 A cold front will continue to move southward through the area this morning before stalling out in Kentucky. An area of low pressure will move along the front tonight into Thursday.
Weak onshore flow today and tonight, becoming offshore on Thursday first with the passage of the pre- frontal trough then later with the front.
319 AM CDT Wed Oct 19 2016 The sfc cold front continues to slide south with a few light showers far west, and will be south of the forecast area by daybreak.
The main weather impact over the short term period will be an approaching strong cold front anticipated to begin moving into the Hill Country and Austin area by 10-12Z Thursday morning. Synoptic models continue to advertise a rather progressive frontal passage and the 00Z suite is showing a thinner moisture pool along the pre-frontal low pressure zone. Cooler temperatures behind the front should keep min RH values in the 35-40% range and prevent much in the way of fire weather concerns.
The unseasonably hot afternoon temperatures are the result of deep layer ridging parked across the region. Otherwise, clear skies with light or calm winds with lows in the lower 60s inland and mid to upper 60s along the coast. The deep layer ridging in place across the region will hold tight through Thursday keeping temperatures several degrees above normal with daytime highs just shy of record levels. This will drive a cold front into the forecast area Thursday night.
A cold front was pushing south through the plains this morning with gusts up to 44 mph at the Springs airport at 2:05 am, and gusts up to 48 mph at the Pueblo airport at 3:32 am. Otherwise, the main story will be the cooler temperatures. Temperatures will continue to be 10 to 15F across the lower elevations most days.
Next cold front extends from South Dakota across Minnesota into the upper peninsula of Michigan. Aloft, broad west-southwest flow spans the northern states with a low amplitude trough over the western US. For Thursday, expect dry and cooler conditions in the wake of an exiting cold front.
146 AM EDT Wed Oct 19 2016 A weak and dry cold front pushes south through the region Wednesday afternoon - still record warmth for Wednesday. A warm front moves back north on Thursday.
Despite a cold front slicing through the region, temperatures ranged from the lower 70s to the lower 80s. This frontal system will stall out near the Arkansas and Missouri state line tonight, and eventually push back north as a warm front early Wednesday morning. A much cooler airmass will spread across the region for Thursday, with highs only in the 60s.
341 AM CDT Wed Oct 19 2016 WV imagery this morning shows upper trof digging esewd across the Four Corners region, with the upper ridge centered over the nrn Gulf Coast beginning to shift ewd in response. Cold front associated with upper low over ern Canada currently draped across srn MO/central OK will be pushed slowly swd today as the trof moves into the Plains. The front will finally get a good swd kick as the trof digs further sewd tonight, and convection will continue to accompany it.
High pressure building over the west will result in a warming and drying trend through Thursday.
A cool northwest flow will prevail across the region today, with high pressure following for the remainder of the week.
/Today/ Upper system will pass into the Plains today approaching the Lower Missouri River valley by this evening.
302 AM CDT WED OCT 19 2016 The cold front has finally slipped south of Lawrenceville as of 200 am and will continue to edge a bit further south before stalling out over far southern Illinois into southern Indiana. Upper trough will sharpen as it moves into the Mississippi Valley on Thursday, helping to boot the cold front and rain off to our east. However, temperatures will recover nicely over the weekend across central Illinois, with more of a zonal flow setting up as the trough shifts to the east. As an upper ridge begins to build across the Plains early in the week, the dry weather pattern will continue over our area.
A dry cold front across the northern third of Arizona will slowly move Eastward as high pressure moves into Arizona from the West.
201 AM EDT WED OCT 19 2016 High pressure at the surface and ridging aloft will keep conditions warm and dry for the next few days. A cold front will approach from the west towards the end of the week. Tomorrow will likely be the warmest day of the week as high pressure continues to dominate the surface pattern with sunny skies. Low temperatures in the low 60s. For Thursday, high pressure lingers to produce a final unseasonably warm day near 85, which will again threaten, but likely fall just short of the record highs at RDU (87) and GSO (86).
554 AM CDT Wed Oct 19 2016 At 3 AM, a Canadian cold front was located across central Minnesota. While there are some questions on the low clouds, it is pretty clear from the water vapor and infrared imagery that we will likely see a broken deck of mid and high clouds move into the area this morning and then linger across areas south of Interstate 94 through this evening. These clouds are associated with a short wave trough moving east southeast across South Dakota. On Thursday night, the models continue to suggest that the ridge of high pressure will be overhead.
216 AM EDT Wed Oct 19 2016 High pressure will build across the region today and tonight. The high will move east on Thursday.
349 AM EDT Wed Oct 19 2016 One more day underneath the upper ridge will result in another unseasonably warm day despite the weakening of the ridge. Digging upper trough/short wave squeezes the ridge out overnight tonight and approaches northwest Georgia during the day Thursday.
At the surface, the cold front had stalled over southern MO and northeast OK with high pressure expanding east from the plains into the upper Midwest. Models show the low level isentropic lift developing over east central KS today. By Thursday morning, the upper level trough axis will be just over northeast Kansas, continuing to push east and out of the area by early afternoon.
SHORT TERM (Today through Thursday): The H5 ridge is finally shifting to the east today, opening the door for a cold front to zip through Deep South Texas.
A rather strong cold front will move across the region tonight causing cooler and windy conditions on Thursday. High pressure aloft will result in warmer temperatures returning again this coming weekend. Amplifying upper trough will move across the Rocky Mountain and into the plains tonight and Thursday while ridge aloft moves into the Great Basin. This pattern will allow cooler Canadian air mass and attendant cold front to plunge southward into southern New Mexico tonight and early Thursday with Thursday high temperatures cooling around 15 degrees.
Surface wise, a western Atlantic ridge extends across the gulf coast region, resulting in northeast to east winds of 15 to 20 knots on our coastal waters.
700 AM EDT WED OCT 19 2016 A deep ridge of high pressure will extend across the region through Thursday.
Most of the high resolution short range models currently have this band too far to the northwest. A cold front is pushing southeast across the Midwest and should reach the Ohio River by about dawn on Wednesday. A stronger upstream trough will drop into the Missouri-Mississippi valley regions Wednesday night and produce a sfc wave or low over the lower Ohio Valley which will then ride up the Ohio River reaching SDF by early Thursday morning. Issued at 400| PM EDT TUE OCT 18 2016 A sharp mid level trough will drive a strong cold front eastward across Kentucky on Thursday with widespread precipitation expected.
345 AM EDT Wed Oct 19 2016 Morning surface analysis showing a surface cold front and weak low pressure to our NW nearing the Ohio River Valley region. That said keep best coverage of clouds across the far NW and therefore the lower overall afternoon highs. Now while the high temps may not exceed the records from 2005 particularly at JKL, we will remain well above normal today areawide. Tonight the frontal boundary will begin to start moving toward the eastern KY, as upper level trough begins to deepen across the plains. These additional clouds will aid in limiting the ridge/valley temp splits. Thursday the upper level trough will continue to deepen across the Mid Mississippi River Valley.
Patchy freezing fog is possible across the I-80 corridor and wild horse reservoir this morning. Dry and quiet conditions will persist through the week as high pressure builds into the week. A high pressure ridge will move across northern and central Nevada. There may be some patches of freezing fog formed from the residual moisture from the rain along the I-80 corridor or near large bodies of water such as wildhorse reservoir.
For tonight, clouds will increase across the region ahead of an approaching cold front from the northwest.
332 AM EDT SAT JUL 9 2016 Cooler and drier air will build into the region today with partly to mostly cloudy skies.
323 AM CDT SAT JUL 9 2016 A cooler and less humid airmass will settle southward into central Illinois today, courtesy of 1016mb high pressure over the Upper Midwest. A weak trough of low pressure analyzed on 07z/2am surface map extending across southern Michigan/Wisconsin will drop southeastward, triggering scattered clouds and perhaps even a few sprinkles across northeast Illinois into northern Indiana. Elsewhere skies are expected to remain mostly sunny with afternoon high temperatures topping out in the lower to middle 80s.
