Wind and temperature forecasts has been difficult over the plains this afternoon as a cold front hangs over the northeastern plains while a Denver Cyclone is spinning up over Douglas County. Thinking is the cold front will push in early this evening, but perhaps not as strong as originally thought, with the Cyclone staying nearby which may keep low clouds out of the western urban corridor, or at least not as thick overnight.
230 PM EDT Sat Mar 31 2018 High pressure will push off to the south and east overnight tonight.
A cold front will bring much colder temperatures for tomorrow along with the possibility of some drizzle in the morning, and again tomorrow night. Temperatures should be cold enough tomorrow night for some light freezing drizzle, but with temperatures at or only barely below freezing and warm surfaces, significant impacts are not expected.
Overnight, the low level jet is not expected to be quite as strong as it was this morning, but southerly winds just off the surface should result in another round of morning MVFR CIGs for most sites. A cold front will approach the KABI terminal tomorrow morning between 12Z and 18Z, and may shift winds to the north before 18Z there.
A cold front was slowly moving through the southern Texas Panhandle this afternoon. However, cooler air and low stratus were lagging well behind the initial wind shift. But the cooler air and low status will make their way southward overnight tonight.
The gradient between Gulf surface ridging and the cold front stalled across north Texas will tighten the gradient considerably, leading to winds approaching 20 knots, with some gusts near 30 later in the afternoon.
339 PM CDT Sat Mar 31 2018 Strong cold front continues to plunge south across the central plains this afternoon, with the initial wind shift just about to move into northeast OK, and colder air lagging behind in northern KS. Temperatures across central NE have struggled to rise above freezing today even with partly sunny skies, which speaks to the overall strength of this airmass. Weak upglide over the cold air will persist with potential for some light freezing rain, possibly as far south as US 412.
622 PM EDT Sat Mar 31 2018 Update A deepening area of low pressure will pull away from lower Michigan tonight.
A cold front is slowly drifting south through the Texas Panhandle and western Oklahoma. It is still uncertain how far south this front will end up, but for Sunday, it is expected to at least move as far south as the Interstate 20 corridor, resulting in cooler temperatures for most of the Big Country. Temperatures in Haskell and Throckmorton counties may only warm into the mid 50s, possibly cooler, with cloud cover also following the front as it moves south. 20 (Sunday night through Saturday) Cold front moves through Sunday night.
327 PM CDT Sat Mar 31 2018 Water vapor shows a short wave trough moving southeast around the upper low over western Hudson Bay. Sunday will be sunny and a tad warmer, but still below average.
612 PM EDT Sat Mar 31 2018 Precipitation chances return tonight with the passage of a cold front. Dry and cooler conditions can be expected through much of Sunday before low pressure brings snow on Sunday night. Otherwise, precip chances will be on the increase with the encroachment of a cold front. resulting in dry and cooler than average weather. particularly over the ridge counties.
106 PM MDT Sat Mar 31 2018 Water vapor continues to show long wave trof covering much of the CONUS.
High pressure will weaken the next couple of days as a low pressure system passes by north of area.
/issued 307 PM CDT Sat Mar 31 2018/ An upper level trough is over the Upper Midwest with northwest flow over West Texas and southeast New Mexico. Temperatures today will warm well above normal with highs in the 80s and 90s across all but the higher terrain. A broad upper trough will be over the northern half of the country on Sunday with an upper low southwest of California. Surface winds across the CWA will mostly be out of the southwest to west on Sunday ahead of a cold front that will begin moving into the area during the afternoon. The cold front will progress across the area Sunday night with a slight chance of very light precipitation developing across the Permian Basin and Lower Trans Pecos.
246 PM EDT Sat Mar 31 2018 A ridge of high pressure will move through from the west tonight then slide offshore Sunday.
A cold front will push across the terminals through the afternoon bringing the wind to the northeast to east and increase speed to around 15 knots. /issued 255 AM CDT Sat Mar 31 2018/ A cold front moving southward through northwest Colorado and southwest Nebraska early this morning will enter the northern part of the forecast area this afternoon, likely stalling not too long after doing so. This cold air will act similarly to the cold front and stall across the forecast area during the day Sunday, while to the southwest of Lubbock southeast to south winds will erode the initial cool surge. This sets up a tricky forecast for the high temperature field with the potential for both a big gradient across the area and a big bust.
233 PM EDT Sat Mar 31 2018 Weak cold front stalled across South Florida between Fort Myers and Naples with limited shower activity. This combined with temperatures in the lower 80s and dew points of 65 to 70 will lead to a 30-40% chance of showers this afternoon ending early this evening. Weak cold front stalls and washes out tonight and Sunday. Warm and dry conditions will prevail through the first half of the work week as high pressure will dominate out weather.
102 PM EDT Sat Mar 31 2018 High pressure will build across the region today. Low pressure will track northwest of Maine tonight into Sunday. High pressure will cross the region today with mostly sunny skies. Low pressure will track northeast across Quebec province tonight, drawing a cold front toward the region late. Precipitation will then persist early Sunday in advance of the cold front. Low temperatures tonight will range from the mid to upper 20s north, to the lower 30s interior Downeast with mid 30s along the Downeast coast. Intense low pressure is expected to pass well to the north of the region early Sunday.
A 1041mb high pressure over southeast Alberta will shift southeast through tonight and maintain dry and cold conditions. High pressure builds over the area tonight, thus very cold temperatures near or below zero across most areas north and east of Lake Sakakawea and the Missouri River, with single digits above in southwest ND.
It's going to be a very cold night across the forecast area with low temperatures in the low teens and upper single digits. Quiet conditions anticipated Sunday along with warmer temperatures in the upper 30s and low 40s.
A low moving across the Great Lakes region will drag along a cold front that will bring widespread rain chances.
342 PM CDT Sat Mar 31 2018 Arctic high pressure has settled over the area today with very cold air persisting through the work week. As the center of the high pressure moves overhead, a very chilly Easter morning is expected.
226 PM MDT Sat Mar 31 2018 The cold front that pushed through Northeast Montana remains well to the southwest. With an upper ridge off to the west, the northwest flow aloft will continue tonight.
Latest guidance suggests a weak inverted trough will develop over coastal waters with a very weak area of low pressure along it. otherwise a partly cloudy and warmer day is expected with high temps around 80 interior, mid- upr 70s eastern counties, lwr 70s coast.
423 PM EDT Sat Mar 31 2018 Current conditions across the area feature high pressure in place across the area with temps warming into the mid 60s this afternoon. This high pressure in place is slowed a bit to exit, so have slow the onset of rain over the area tonight. There will be some uncertainty as to a lull in the precip Sunday morning into the afternoon before the warm front develops and lifts north Sunday evening. By this time, a warm front develops aligning along northern Kentucky.
113 PM EDT Sat Mar 31 2018 Shallow cool air behind a cold front stalled in south Florida had created BKN-SCT010-025 south of a line from KSRQ-KGIF. Tampa sounding showed cool dome behind cold front was 3,200 feet thick. Front will dissipate through the weekend with high pressure building in in its place.
306 PM CDT Sat Mar 31 2018 High pressure centered from southern Alberta through northeastern MT continues to sink southeast, weakening the tight pressure gradient.
248 PM CDT Sat Mar 31 2018 A cold front moved through the area during the afternoon hours. Temperatures ahead of the front in western Illinois reached the low 60s. The lowest daytime temperatures are forecast for the south, near or slightly below freezing, with readings in the mid to upper 30s to the north. Arctic high pressure will fill in the void post these systems and bring with it cooler than normal temperatures to the area.
Snow levels will initially begin above 4000 feet, but rapidly lower as an impeding Pacific cold front pushes southeastward across the Northern Rockies by Sunday night.
307 PM CDT Sat Mar 31 2018 An upper level trough is over the Upper Midwest with northwest flow over West Texas and southeast New Mexico. Temperatures today will warm well above normal with highs in the 80s and 90s across all but the higher terrain. A broad upper trough will be over the northern half of the country on Sunday with an upper low southwest of California. Surface winds across the CWA will mostly be out of the southwest to west on Sunday ahead of a cold front that will begin moving into the area during the afternoon. The cold front will progress across the area Sunday night with a slight chance of very light precipitation developing across the Permian Basin and Lower Trans Pecos.
303 PM EDT Sat Mar 31 2018 Precipitation chances return tonight with the passage of a cold front. Dry and cooler conditions expected through much of the day Sunday before the next system brings snow to the region Sunday night. Warm air advection ahead of the front will keep temperatures from falling much until the cold front begins to cross shortly after midnight. resulting in dry and cooler than average weather. particularly over the ridge counties.
/Issued 1036 AM EDT Sat Mar 31 2018/ High pressure and dry conditions through today. Dry high pressure will hold over the CWA through tonight. the region will be under the influence of zonal flow in the mid and upper levels and a stalled weak frontal boundary across the northern portion of the state in the lower levels.

949 AM EDT Sat Jul 29 2017 High pressure builds in from the northwest while low pressure tracks well south of the Gulf of Maine, resulting in a dry and mostly sunny weekend.
Isolated afternoon and evening thunderstorms today and Sunday, mainly over the higher terrain. Moisture at mid-levels will be sufficient for a few afternoon/evening thunderstorms both days, mainly in the higher terrain.
Drier and slightly cooler air will continue to move into much of Oklahoma this afternoon. Surface dewpoints will continue to decrease in most areas in Oklahoma and north Texas this afternoon with the lowest values in northern Oklahoma. However, models still indicate multiple MCS episodes as s/wv troughs progress over the retrograding ridge.
An inverted trough will remain over Arizona today and tomorrow, along with above normal moisture values.
Guidance is consistent in pushing the pre-frontal trough and its convection south of the coast in this time frame. With The cloud cover and rain expected today, have went below seasonal, leaning towards the cooler GFS MAV numbers for today. Did go a bit warmer north of Highway 84, with this portion of the area likely seeing some heating this afternoon, and along the immediate coast, with this area seeing the cooling effects of the rain last today.
637 AM CDT Sat Jul 29 2017 Large area of showers and isolated thunderstorms moving through central Louisiana this morning ahead of a cold front that is making it's way thru Louisiana. /issued 356 AM CDT Sat Jul 29 2017/ A digging upper level trough over the eastern US will swing an unusual late July "cold front" through the area this afternoon through tonight.

1223 PM EDT Sat Jul 29 2017 Low pressure tracks well south of Long Island today, and well east of the area tonight.
Moderate northeast surface wind will ease during the afternoon as the high becomes centered over lower Michigan. Southeast Michigan positioned along the downstream flank of expansive high pressure, maintaining a deep layer of dry air within prevailing northeast flow today. Under nearly full insolation once again, this will bring readings into the lower and middle 80s all locations.
Building high pressure will return dry and seasonable weather for the later half of Saturday through the start of the work week. Upper low continue to pivot off to the east with the area of rain over northern WV diminishing in size with the loss of the moisture feed from the parent system off the coast. High pressure will remain in place through the start of the week.

1245 PM EDT Sat Jul 29 2017 Dry weather will continue through the weekend as a ridge of high pressure gradually settles across the region.
This morning's satellite imagery and upper-air analysis indicates the presence of an inverted trough positioned across Navajo and Apache counties. This trough is forecast to slowly move westward throughout the day, and provide forcing to enhance thunderstorm development. A band of thick, but narrow cloud cover associated with this trough extends roughly from Payson to the Four Corners. Thunderstorm steering flow is expected to be from the northeast ahead of the trough, with speeds of around 10 knots over southern Coconino and Yavapai Counties. An inverted trough will remain over Arizona today and tomorrow, along with above normal moisture values.
803 AM EDT Sat Jul 29 2017 Upper-level low pressure system will cross over the area today and then move offshore later today into Sunday. High pressure builds overhead Sunday through much of the week. A cold front may approach the area late in the week. There had been concern earlier about the possibility of another round of heavy rainfall as the upper level low crosses the area. Cool for late July today/tonight with highs in the low/mid 70s and lows in the 50s to low 60s. High pressure builds overhead Sunday allowing for a very pleasant late July day with highs near 80, comfortable dewpoints in the 50s, lots of sunshine, and relatively light winds.
1124 AM EDT Sat Jul 29 2017 Hydro High pressure from Canada will bring fair weather with low humidity through the weekend.
Isolated showers will develop this afternoon across the region and mostly in eastern Montana and along the higher terrain. The ridge will be a little stronger tomorrow, resulting in only a slight chance for a thunderstorm. Temperatures will be a little warmer for Sunday, mainly in the low to mid 90s.
A surface cold front has pushed roughly halfway through the forecast area, oriented in east to west along the TN River. Looking upstream, the airmass behind the front will be slow to modify, with dewpoints remaining in the lower 70s across TN. A rather pleasant day is on tap across the TN Valley, as high pressure builds southward across the area. Northerly flow will advect cooler and drier air into the region and high temperatures will only rise into the lower to mid 80s. Depending on how much our dewpoints fall, temperatures will likely drop into the lower 60s, with a few spots dropping into the upper 50s.
A couple of large- scale features in play this weekend with the GOES-16 mid and upper level water vapor imagery depicting two westward tracking upper lows. We have the added influence of a weak inverted trough across northwest Mexico, nosing into southern Arizona today and Sunday.
This will keep ridge axis well south of the area, with offshore flow increasing in strength. Ridge axis remains well south of the waters as a frontal boundary shifts southward toward north Florida later tonight.
1030 AM EDT Sat Jul 29 2017 14z sfc analysis shows high pressure slowly pushing into the area. So far this has mot been enough to clear out the low clouds across most of eastern Kentucky. The latest surface map features unseasonably deep low pressure across the mid-Atlantic states, with high pressure building in from the Great Lakes. Aloft, a stout upper level low is moving southeast across the central Appalachians. Very pleasant weather will be on tap for our area through the weekend, as high pressure gradually builds in from the northwest. That said, much of the eastern half of the lower 48 will remain under the influence of general long wave trough.

926 AM CDT Sat Jul 29 2017 Another pleasant day is on tap with high pressure centered over the western Great Lakes. The ridge axis locates right over southern Wisconsin tonight, with light winds, clear skies, and good radiational cooling. High pressure across the Upper Great Lakes and Wisconsin. Forecast soundings show drier air in the lower levels, although just enough for few fair weather cumulus. Northwest upper flow across southern Wisconsin with a ridge across the plains. High pressure across the upper Great Lakes and Wisconsin. Forecast soundings show a lot of dry air in the lower levels although just enough for scattered fair weather cumulus. With the high across the area tonight, some river valley fog possible, mainly in the Wisconsin river valley.
724 AM EDT Sat Jul 29 2017 Pleasant conditions expected through the weekend as high pressure building into the region will keep the North Country dry and seasonably cool. High pressure continues to build into the region and should keep the North Country under quite pleasant conditions through the weekend.
628 AM CDT Sat Jul 29 2017 After some early morning valley/bog fog, expect mostly sunny/clear skies today into tonight as high pressure continues to dominate the regional weather pattern.
After minimums in the lower to mid 80s, temperatures were already reaching the upper 80s with heat indices The morning sounding at Key West showed little change in total column moisture, albeit a bit drier below and more moist at mid levels, with negligible inhibition. impressive deep troughing along the U.
Temps look to top out within a few degrees of 90 today with continued mugginess bringing heat indices into the lower 100s.
An upper level ridge will begin to build northward from the southwest into the northwest today and tonight. High temps today will be similar to or a degree or two warmer than yesterday.
Cold front has exited the mid state, and with it goes the rain and all that muggy air. Skies are clearing out across Middle Tennessee this Saturday morning, and cooler, drier air is riding a surprisingly strong NNE flow into Middle Tennessee.
241 AM PDT Sat May 20 2017 High pressure aloft will build in from the Eastern Pacific towards California this weekend. An upper level ridge of high pressure along the CA coast will continue to nudge closer across central and srn CA today. A weak upper level trof is forecast to move into Nevada on Sunday and cause heights/thickness lvls to lower a tad on Sun over SoCal.
This low and vort max will slowly lift into Neb by dawn and cross the state tomorrow. Sat: Plenty of clds with the upr trof remaining overhead. Aloft: The longwave trof will remain over the Cntrl USA even as the low departs into Canada. The model consensus suggests N-NW flow Wed-Thu with a deamplifying Wrn ridge arriving here Fri. This high will depart to the E Sun. Even though the low currently affecting the rgn will be in Canada. it will still impact the rgn as another cold front plunges S thru the CWA Mon on its backside. Another chilly high will drop in Tue and as this high conts S. except a one day interruption of much cooler than normal (though not as bad as today or Sat).
216 AM EDT Sat May 20 2017 Low pressure over the southern Plains will move slowly northeast into the upper Great Lakes this weekend causing showers and thunderstorms at times across our area through Sunday morning, with best chances late Saturday afternoon and Saturday night as the cold front associated with this system approaches.
410 AM CDT Sat May 20 2017 Strong upper low will continue to lift northeastward today and tonight right across our eastern zones as evidenced by upper QG forcing. Typical for a mature cyclone, the shower activity will become a bit more scattered on the southwest flank of the occlusion as the day progresses, especially from Sioux City to Storm Lake, and northward to Sioux Falls and Yankton. Despite the high pops in the trowal locations, opted for an occasional wording to the showers where categorical pops are present today, as the radar is showing a rather intermittent rain regime. Warmed up the lower pop areas forecast for this afternoon, basically in northwest IA and extreme southeast SD over guidance values.
240 AM MST Sat May 20 2017 Broad area of low pressure will continue to exit the Four Corners region with high pressure building in from the west.
