652 PM CDT Sun Apr 16 2017 In the wake of the cold front which pushed through the area early this morning, dry conditions have been observed for most areas through Sunday morning. Building high pressure over southwestern Iowa is generating an expansive area of convergence near 850 hPa, along the northern extent of the residual moist airmass from yesterday. The cold front which pushed through the local area this morning has stalled over southern Missouri underneath weakening flow aloft. Will see mostly dry conditions Monday as weak mid-level ridging returns to the Central Plains, briefly.
1023 PM MDT Sun Apr 16 2017 Upper level analysis has upper trof shifting east across the northern CONUS with ridge building across the Rockies. At the surface, high pressure resides across the central plains with a weak cold front across North Dakota. High pressure will slide to the southeast across the Dakotas with winds slowly becoming southerly after midnight. Weak frontal boundary to the south will lift back north into the area as a warm front during the day as low pressure develops along it across eastern WY. The best chances for rainfall late Monday into Monday night will be mostly east of the Black Hills as low pressure moves quickly across SD during this time.
/issued 355 PM CDT Sun Apr 16 2017/ Latest surface analysis showed a ridge of high pressure extending from the western Atlantic to Carolinas/Georgia coast to east Texas.
1152 PM CDT Sun Apr 16 2017 In the wake of the cold front which pushed through the area early this morning, dry conditions have been observed for most areas through Sunday morning. Building high pressure over southwestern Iowa is generating an expansive area of convergence near 850 hPa, along the northern extent of the residual moist airmass from yesterday. The cold front which pushed through the local area this morning has stalled over southern Missouri underneath weakening flow aloft. Will see mostly dry conditions Monday as weak mid-level ridging returns to the Central Plains, briefly.
A cold front is currently located along the Ohio River.
Surface analysis this evening places a weak cold front over Southern Illinois, Missouri, and Northern Oklahoma. Kept the highest pops during the evening toward NW Tennessee. Temps will range from the lower 70s north to 80 south.
Isolated showers over the Atlantic waters will remain over the waters tonight as they rotate around the high.
835 PM EDT Sun Apr 16 2017 A cold front will cross the area Monday morning.
Main area of focus will be around the stalled out cold front located in southeastern Kansas. High temperatures will be in the low to mid 70s.

1249 AM EDT Mon Apr 17 2017 A cold front will move southeast across the area early tonight.
754 PM EDT Sun Apr 16 2017 Numerous showers and thunderstorms will occur before a cold front pushes through later tonight.
The closed upper level low pressure system off the southwest coast of Oregon is now moving into southwest Oregon. A precipitation band is developing out ahead of the low that stretches from Mt Adams back down to southeast Oregon. Behind this there is convection developing over southwest Oregon just ahead of the center of the low. The track of the low will take it across central oregon around midnight and then into northeast Oregon by sunrise Monday.
943 PM EDT Sun Apr 16 2017 A cold front will move southeast across the area early tonight.
1038 PM EDT Sun Apr 16 2017 Building high pressure will ensure a dry start for the new week; however, the latter half will feature increased rain chances as a series of low pressure systems affect the region. A quick late eve update was issued to adjust clouds and pops for additional, albeit isolated, convective development along an immediate-prefrontal trough sweeping across Ohio. Building high pressure will ensure a dry Monday with seasonal temperature. Broad high pressure across the Great Lakes and Northeast will allow for tranquil weather during this portion of the forecast.
Given light winds and largely clear skies, radiational cooling will be rather efficient, lending to low temperatures in the low to mid 20s in the central and northeast zones and near freezing across the southwest portions of the forecast area. A quasi-stationary frontal system remains draped across northern Montana with colder temperatures and cloudier skies north of the boundary and partly cloudy skies and warmer temperatures south of the boundary.
705 PM EDT Sun Apr 16 2017 A cold front will move southeast across the area early tonight.
257 PM CDT Thu Oct 19 2017 Upper level ridging will spread across the area tonight as troughing deepens over the Rockies.
324 PM CDT Thu Oct 19 2017 High pressure will continue to shift eastward slightly toward western Virginia overnight. This actually looks reasonable based on the flow around the high from northern Georgia/South Carolina.
Weak high pressure moves away with a return south flow setting up into Friday. Weak high pressure moves away with a return south flow setting up into Friday. High A ridge of high pressure nosing into southern WI is proggd to shift to the east this period setting up a reinforcing surge of warmer air.
SHORT TERM (Now through Friday night): The H5 trough continues to sweep into the western half of the US, with the first wave just now moving northeast into central Texas. Morning sounding showed moisture is trapped in the lowest 5000 feet, with strong dry air cap above. Light winds and ample moisture at the sfc will lead to some patchy ground fog in grassy areas tonight, but if the drier air can focus llvl moisture closer to the sfc, some more denser fog might be a possibility for the lower valley around sunrise.
Windy conditions look to persist through the weekend with cooler temperatures expected.
246 PM MDT Thu Oct 19 2017 GOES WV shows PV center at base of upper trough moving NE over the four corners region. Main branch of the trough will move into the region by Friday morning bringing increased SW winds. Winds will pick up ahead of the trough over portions of southern Denver and the plains with sustained winds from 12 to 17 mph and gusts to 30 at times.
337 PM CDT Thu Oct 19 2017 Through Friday: A ridge axis will continue to move east through the ArkLaMiss the rest of today and will be situated to our east on Friday. Mostly sunny skies with warm temps in the low 80s will persist the rest of this afternoon. The coolest temps will be realized across the Golden Triangle and northeastern portion of the CWA with high clouds and higher dewpoints helping to keep warmer temps in the low to mid 50s across the southwest Delta. Anomalous H850 temps in the 90th percentile will continue and help daytime max temps once again reach the low 80s Friday afternoon.
315 PM EDT Thu Oct 19 2017 A weak and dry cold front will cross the area tonight with little fanfare. Other than slightly cooler temperatures on Friday, high pressure will remain the dominant influence on regional weather conditions through the upcoming weekend with temperatures remaining well above late October norms.
Another cool fall morning with temperatures already rising into the low to mid 50s as of 930AM this morning underneath a high pressure system centered over western NC. Made some minor trend adjustments to the dewpoints and temperatures, but daytime highs in the low to mid 70s with dewpoints in the upper 40s/near 50 are on track.
/issued 900 AM EDT Thu Oct 19 2017/ An upper ridge in the Gulf of Mexico will provide a stable and generally dry air mass for much of the area. High pressure centered over the Tennessee Valley this morning will maintain northeasterly winds today. It will be warm day with the highs 3 to 6 degrees above norm.
1105 AM MDT Thu Oct 19 2017 Broad upper ridge covers much of the CONUS, with partly cloudy skies over the northern plains. An upper level trough will cross the Rockies Friday night with a cold front.
High pressure moves away with a return southerly flow setting up into Friday.
The lower elevations, by and large, should remain dry.
323 PM EDT Thu Oct 19 2017 High pressure will dominate the weather through the weekend.
300 PM EDT Thu Oct 19 2017 High pressure will remain from the mid Atlantic to the Tennessee Valley today while a weak, dry cold front pushes southeast into the Great Lakes. The front will wash out tonight, while high pressure strengthens over the Ohio Valley into Friday.
High A ridge of high pressure nosing into southern WI is proggd to shift to the east this period setting up a reinforcing surge of warmer air.
A mostly persistence forecast again as high pressure remains in control.
414 PM EDT Thu Oct 19 2017 A weak and dry cold front will cross the area tonight with little fanfare. Other than slightly cooler temperatures on Friday, high pressure will remain the dominant influence on regional weather conditions through the upcoming weekend with temperatures remaining well above late October norms.
Else, very light SHRA may greet LBB and PVW later today and tonight as a decaying upper low arrives. There's the developing ridge to our east and a weak, but deepening trough to our southwest across the Trans-Pecos. Further to the west, over southern NV, there's another weak trough causing a bit of unsettled weather. A front is passing across the Great Lakes region and well back to the east in the Pac NW is a trough creating considerable storminess for western Washington and northwestern Oregon. Now, let's talk about that first trough. However, the chance still persists near the TX/NM border where moisture return has been the highest. Now for the Pac NW trough. Models are in good agreement this feature will continue to deepen as it moves eastward, dragging a cold front along with it.
110 PM EDT Thu Oct 19 2017 High pressure will maintain dry and warm weather through the weekend. Clear skies today will only briefly be interrupted by a weak and dry cold front dragged through by a high latitude system moving east near James Bay. Several models show low-level moisture associated with the weak front, dropping down from the southern Great Lakes this evening, eventually pooling near the higher elevations. High pressure will re-build through the weekend, keeping it warm and dry.
612 PM EDT Thu Oct 19 2017 High pressure will maintain dry and warm weather through the weekend. High pressure will re-build through the weekend, keeping it warm and dry.
252 PM CDT Thu Oct 19 2017 High pressure remains in control of the current Midsouth weather with light south winds running temperatures in the mid and upper 70s. about 3 to 5 degrees warmer than yesterday.
111 PM EDT Thu Oct 19 2017 A weak cold front will push across the forecast area this afternoon. High pressure will quickly build back over the area and linger through the weekend. A weak cold front across SERN WI will move across the forecast area this afternoon. High pressure quickly builds back over the forecast area tonight and will remain anchored over the area into weekend. The short term begins with high pressure centered in southwest PA and extending over the Ohio Valley. The airmass will be dry and there will be an upper ridge in place across the region.
324 PM CDT Thu Oct 19 2017 Weak mid/upper level low apparent on satellite imagery, supported by southern jet, is moving slowly NNE out of SE New Mexico into the South Plains and will eventually weaken as it moves through the Texas Panhandle into Oklahoma over the next 24 hours. Whatever energy remains from the low, will get absorbed into the more potent Pacific trough that will shift off the Pacific Ocean later tonight, with the base spreading across northern California. The negatively tilted trough is struggling to produce much more than thick mid/upper level cloud cover today across our CWA with dewpoint depressions of 25 to 35 degrees holding steady at the surface.
/ISSUED 1002 AM CDT Thu Oct 19 2017/ Today the main story will be the start of moisture return flow and the dreaded warm front that pushes north tomorrow to bring back summer like conditions. This moisture will gradually creep north tonight and then greatly increase tomorrow as LLJ develops in response to lee troughing over the high plains of the Rockies.
High pressure will remain north of the forecast area.
414 PM CDT Thu Oct 19 2017 Southeast winds have made a comeback, bringing a return in southerly flow in the low levels across the region. This will be very noticeable over the next couple of days as high temperatures will run some 5 degrees warmer compared to the past couple of days along with higher dewpoints,which will result in higher relative humidities.
Windy and cooler conditions are expected Friday as weather system and associated cold front move through the region.
409 PM EDT Thu Oct 19 2017 High pressure will remain over the eastern conus through the upcoming weekend.
141 PM CDT Thu Oct 19 2017 140 PM CDT A quiet night ahead with the high pressure ridge shifting from overhead this afternoon to east of the area by daybreak. A slight south wind late will ease the rate of cooling with lows forecast in the mid-upper 40s in outlying locations, to the lower to mid 50s in the metro.
212 PM EDT Thu Oct 19 2017 High pressure will maintain dry and warm weather through the weekend. Clear and warm this evening as high pressure maintains control. Several models show low-level moisture associated with a weak front, dropping down from the southern Great Lakes late this evening, eventually pooling near the higher elevations. High pressure will re-build through the weekend, keeping it warm and dry.
The upper level ridge to our west will build overhead overnight. Afternoon highs in the lower 80s this afternoon will give way to overnight lows in the lower 50s across our northern zones to lower 60s closer to the coast.
A southerly breeze will persist overnight in assoc/w a relatively tight MSLP gradient on the eastern periphery of the lee trough in western KS. With southerly flow /warm advection/ overnight, expect lows Fri morning to be warmer than previous days, ranging from the mid 40s in eastern CO (where the MSLP gradient will be weaker) to mid/upper 50s east of Hwy 83 (where the MSLP gradient will remain tight).
336 PM EDT Thu Oct 19 2017 A cold front will cross the region tonight and will be followed by high pressure on Friday.
606 PM EDT Thu Oct 19 2017 High pressure will remain over the eastern conus through the upcoming weekend.
Still expecting dry conditions with partly to mostly cloudy skies across the region and high temperatures in the lower 80s.
227 PM EDT Thu Oct 19 2017 Clear skies and seasonable temperatures prevailed across the lower Ohio Valley thanks to high pressure centered over the lower Appalachians.
Aloft - Troughiness over and right off the eastern sea board shifts out over the Atlantic Fri as a ridge from the central Gulf of Mexico northward through the Mississippi Valley slides east. Surface - High pressure centered in the southern Appalachian Mountains tracks into the central Appalachians Fri. While moisture increases for Fri the upper ridge right over head will counteract this. Thanks to the upper ridge temperatures will run above normal. High pressure centered along eastern CONUS to continue easterly low level flow with a 10-30% chance of Atlantic showers through the weekend.
High pressure is over the southeast states at the surface and aloft. A trough is over the Pacific Coast. Through the next couple of day the ridge will continue east bound and the trough will advance toward the plains. This will serve to gradually break down the upper ridge locally and allow a few showers and storms by Friday with a few streamer showers moving in by the morning.
Cooler temperatures and mountain snow/valley rain expected. More significant rain and precipitation hitting this weekend A cold front expected late tonight will result in showers, wind shift from the northwest and falling temperatures. Highs Friday should be 15 to 20 degrees cooler than today per latest forecast.
Expect winds to decrease later this evening before backing to the south by tomorrow morning in response to a high pressure drifting through the eastern Great Lakes. A dry cold front is beginning to march across the Great Lakes as advertised with little in the way of even clouds with it.
253 PM EDT Thu Oct 19 2017 Afternoon surface analysis shows an area of high pressure centered near the Eastern Tennessee and Kentucky borders this afternoon. This will keep upper 30s to lower 40s in the eastern deeper valleys with mid to upper 40s on the ridges. The upper level ridge does start to march east Friday night, and some return moisture in the upper levels could lead to increase high clouds overnight. Despite this we will still see some ridge/valley temperature split and patchy dense valley fog. We are expecting a ridge of high pressure to bring warmer than normal temperatures and dry conditions to eastern Kentucky over the weekend.
1048 AM PDT Thu Oct 19 2017 The forecast will remain wet and breezy at times today into Friday as a low pressure system slowly sags through the region.
Dewpoints have tumbled into the mid 20s and 30s behind a weak cold front supporting a dry boundary layer while steadily increasing subsidence ensures clear skies through the column. High confidence that the southern half of the CWA will decouple with temperatures falling toward the cooler MET/MAV numbers.
134 PM EDT Thu Oct 19 2017 Mostly clear skies and a warming trend are expected into the weekend, as a dry upper ridge builds across the region.
228 PM EDT Thu Oct 19 2017 High pressure will remain over the eastern conus through the upcoming weekend.
130 PM EDT Thu Oct 19 2017 Surface analysis shows an area of high pressure centered just to our south across the greater Tennessee Valley. Otherwise nearby high pressure will continue to provide clear and calm conditions across eastern Kentucky. Strong ridging will continue to hold over the region through Friday with heights continuing to build. Overnight lows Thursday night will remain chilly with lows into the upper 30s to around 40 with ridges staying closer to the upper 40s. An anomalously strong upper ridge will be over the southeast CONUS as the period starts, providing dry and mild weather for the local area.
310 PM MDT Thu Oct 19 2017 Broad upper ridge covers much of the CONUS, with mostly sunny to partly cloudy skies over the northern plains. At the surface, weak lee trof extends across Montana into northeast Wyoming and western South Dakota. An upper level trof will cross the Rockies Friday night with a strong cold front moving through the northern Plains.
A cold front approaching from the upper Midwest has largely stalled, as has the line of convection just ahead of the front. A cold front west of the area is still forecast to move toward the area into northwest IL this evening. And with hurricanes Jose and Maria sitting out east in the Atlantic, the trough in the west will remain out there as well.
749 PM EDT Wed Sep 20 2017 A weak mid level trough will move east of the area today. Over the next several days, a stagnant weather pattern will set up, with mid-level ridging and high pressure near the surface. Fog potential is the greatest concern for tonight, with a favorable setup in the wind and pressure pattern (overall light flow with the main axis of the boundary-layer ridging just to the east). Strong H5 ridge will be the dominant feature for much of the forecast period. The ridge will keep Jose off the East Coast and away from the Ohio Valley, and later on Maria.
Weak high pressure continues to influence the weather across Middle Tennessee both at the surface and aloft.
733 PM EDT Wed Sep 20 2017 High pressure remains centered northwest of the area through the weekend while Tropical Cyclone Jose will to meanders south of the New England coast. ISOLD convection continuing over the higher terrain well W of the FA into early this morning w/ near term guidance keeping that convection from entering (wrn portions of) the FA. Any convection from the lingering moisture stays west and south of the fa Thursday as high pressure continues to dominate into the weekend.
Issued by National Weather Service RENO NV 832 PM PDT Wed Sep 20 2017 A cold front continued to work across northern NV this evening with a solid band of moderate precipitation occurring along the I-80 corridor. As cooler air works into northern NV behind this front, gradients will relax and winds will continue to decrease. Latest model simulations indicate the front and band of rain/snow will continue to track slowly southeastward through the night into Thursday morning, affecting the Highway 50 corridor. Low pressure and cold front remains on track with rain and snow passing across much of northeast Nevada tonight and Thursday.
/issued 405 PM CDT Wed Sep 20 2017/ (Tonight and Thursday) (Rest of the afternoon) A 850mb thermal ridge has slowly shift east into our area. With dewpoints in the low 60s we can expect index values to climb between 101-103 which will be just below heat advisory levels. A 500mb ridge will suppress the convection from becoming too widespread and keep it confined to just a small area. A deep upper level trough will begin to move out of California and into the four corners region allowing for the weak ridge to begin to erode. With this erosion of the ridge and increasing divergence aloft, shower and thunderstorm activity could be more widespread tomorrow afternoon and evening. Temperatures on Thursday will be a little "cooler" than what we have seen the past couple of days.
A ridge of upper high pressure could contribute to some fog development again overnight, but will also keep dry weather and above normal temperatures across the area through the weekend. Ridge of high pressure aloft will keep warm and dry conditions in place over central Indiana.
700 PM CDT Wed Sep 20 2017 A cold front west of the area is still forecast to move toward the area into northwest IL this evening. And with hurricanes Jose and Maria sitting out east in the Atlantic, the trough in the west will remain out there as well.
701 PM EDT Wed Sep 20 2017 High pressure both at the surface and aloft will build overhead through the weekend. High pressure both at the surface and aloft will build over the region as the upper-level disturbance shifts to the south tonight. to the lower and middle 60s across most other locations.
/00Z TAFS/ Slowly dying convection from weak disturbance near the Big Bend could create some variations in the timing of the low cloud cover forecast that reflects mostly persistence.
A cool, upper level trough will dominate the western portion of the country through the workweek maintaining cooler than average temperatures and breezy conditions. A weak cold frontal boundary remains draped across north-central California this evening. IR satellite currently shows an area of convective precipitation off the Oregon coast associated with a cold upper trough that is digging south. The trough is forecast to move southeast and inland across northern California late tonight and Thursday morning. A cooler airmass will sweep across our area with the trough on Thursday with 850 mb temps now forecast to drop as low as 4 deg C. Thus, we can expect cooler temperatures in most areas tomorrow.
The exception is a wide swath of showers which extends from SW to NE (to the northwest of a cold front) across northern NV and into S-Central Idaho. The showers will continue through Thursday as an upper trough settles into the region, with the bulk of the showers expected near the Nevada border. Light snow accumulations will continue in the higher elevations mainly above 6000 feet.
afternoon showers are possible in the higher elevations.
With high pressure over the area, expect clear skies over the area overnight.
Overnight, persistence seems to be the winning strategy, with min temps bottoming out in the low to mid 70s.
938 PM EDT Wed Sep 20 2017 High pressure both at the surface and aloft will build overhead through the weekend. High pressure both at the surface and aloft will build over the region as the upper-level disturbance shifts to the south tonight. to the lower and middle 60s across most other locations.
