132 PM CST Sat Mar 10 2018 A cold front continues to push south across the central plains this afternoon. The winds will pick up behind this front tonight as an upper level short wave trough located over northwest Nebraska/southwest South Dakota dives southeast which will help drive the front southward. On Sunday, another short wave trough will approach the Panhandles from the west. A northwest flow aloft will continue until an upper level ridge pushes onto the plains by mid week.
A weak low pressure system moving through California will tap a very moist subtropical air mass to bring periods of rain through tonight, diminishing Sunday morning.
A ridge of high pressure has built over the region providing clear skies this morning.
Otherwise, an upper ridge will be accompanied by mostly clear skies, light winds, and slightly above normal temperatures today. Ridging will bring warming aloft today through Sunday, but surface warming will lag behind.
1202 PM EST Sat Mar 10 2018 Dry weather returns this weekend under high pressure. Dry conditions will continue on Sunday as a developing low pressure system begins to lift out of the southeast.
301 PM EST Sat Mar 10 2018 Brief high pressure through early tonight.
Cold front should move through in the heart of the day, between about 9am and 2pm northwest to southeast. This timing certainly make the high temperature forecast difficult. Will see a cooler night Sunday night with lows mainly in the 50s.
309 PM CST Sat Mar 10 2018 A weak boundary is currently just south of the forecast area, with showers brushing the lower tier of counties. A low pressure system will lift into the MS Valley on Sunday and into the TN Valley by Sunday evening.
Skies will continue to clear throughout the daylight hours today, as upper level ridging builds into the Northern Rockies. While temperatures will not be as warm as they were yesterday, bountiful areas of sunshine should be observed this afternoon as the ridge moves overhead. - Moldan A few morning snow showers are possible over the Little Belt mountains, otherwise expect sunny skies to develop over much of the region today, as an upper level ridge of high pressure begins to build over the region.
216 PM MST Sat Mar 10 2018 The approaching western upper ridge will dominate the weather for NE MT through mid-week.
257 PM MST Sat Mar 10 2018 Gusty northerly winds had developed across the plains behind today's cold front. Sunday will feature lighter winds as high pressure builds across the Northern and Central High Plains. There are some high clouds advertised to spread east, but that will be difficult as they run into the developing upper level ridge over Colorado.
A broad upper low pressure system then drops south-southeast out of Canada.
All in all, high pressure to prevail. Surface ridging will keep winds on the lighter side today. It will be a nice today across southern WI today with high pressure overhead. Variable winds will come around to the east this afternoon, so expect lakeshore areas to remain a bit cooler once again. Temperatures will be just a notch warmer than yesterday. Mid level clouds will slide into at least the western half of Wisconsin tonight as low pressure tracks into the Midwest. Clouds will keep us slightly warmer for the overnight hours, so expect lows in the mid to upper 20s there.
1235 PM EST Sat Mar 10 2018 Dry weather returns this weekend under high pressure. Dry conditions will continue on Sunday as a developing low pressure system begins to lift out of the southeast.
A developing low pressure system will be tracking toward us along a nearly stationary frontal boundary during the period. Precip chances will increase further north as the low pressure system approaches, but for now will keep PoPs in the chance range for northern areas as it is unclear how much precipitation will make it that far north and there may be some downslope flow west of the mountains. Precipitation expected to be all rain in the short term as thermal profiles show freezing levels well above the terrain during the precipitation. However, though the models are in somewhat better agreement, the slightest shift with the track of the low will change the forecast for our area.
119 PM EST Sat Mar 10 2018 Lake effect snow showers will taper off this afternoon and tonight, as weak high pressure pushes into the region. Second, high pressure nosing down from the Great Lakes will bring dry air and downward motion into NY/PA.
1226 PM EST Sat Mar 10 2018 High pressure will build into the area from the northwest today through Sunday.
Winds will be variable this afternoon then become N/NE and gusty behind a cold front that will move across the area tonight. A cold front will move through overnight with strong north winds developing behind the front. Cooler and drier air will overspread the area tonight as main upper disturbance drives a cold front south through the area. Cooler temperatures will continue through the early part of the upcoming week as cool Canadian air continues to filter south into the southern Plains.
1227 PM CST Sat Mar 10 2018 Issued Red Flag warning for part of our Kansas CWA for the remainder of the afternoon as RH values have dipped to 20 percent and winds are expected to increase behind a cold frontal passage. Otherwise, a dry and relatively benign low pressure area is forecast to move southeast over the CWA tonight. Models continue to suggest a deepening trough over the southwest U. This trough will lead to a southeast flow of warm and dry air.
However, think that chances of any freezing drizzle are pretty low, so kept everything as snow for now. Considering there was some fog in that area while the trough was over central ND last night, can't rule out some patchy fog formation. High pressure will be building into the area with northwesterly winds. Think that clouds will keep the eastern counties from seeing their warm spots in the trees, allowing more uniform high temperatures from the lower to mid 30s. Late in the period some cooler air and precipitation are expected.
351 PM EST Sat Mar 10 2018 High pressure will build south into the Central Great Lakes Sunday and linger through the weekend.
A warm front is progged to mix slowly north across northern Oklahoma today but remaining south of the Kansas state line where better instability will remain. Cooler and drier conditions will arrive on Sunday with northerly flow resulting in below normal temperatures across the region. A few scattered showers are possible later this afternoon through the evening across the area, as a cold front and associated upper level system approach from the northwest.
While a mid level wave moves across the TN Valley Sun/Sun night, mid level short wave ridging will traverse Lower Mi. Slightly higher mid level thicknesses on Sunday and full sun will support a little warmer highs (mainly from the mid 30s to 40).

324 AM CST Fri Feb 16 2018 High pressure building into the region today with full sunshine but cool temps.
High pressure was building across the Northland in the wake of this morning's cold front. The trough will swing through the Northland this evening with a brief increase in cloud cover expected. Nudged overnight lows a little colder with readings in the -5 to -15 degree range for most locales, but a little warmer near Lake Superior in northwest Wisconsin. Friday appears sunny with cooler temperatures in the teens and 20s above zero. As the long wave trof retrogrades slightly, this will allow for more wave amplification in the part of the stream originating in the Pacific NW and northern Rockies. A few snow showers, areas of light snow, or perhaps some freezing drizzle will be possible Friday night/Saturday as warm advection and a slow erosion of the latest arctic airmass commences.
256 AM EST Fri Feb 16 2018 Cold front is currently making very slow headway through southern Indiana. A transient area of high pressure builds in tonight, and we'll cool to around the freezing mark, which is actually still just a shade above normal for mid-February. As for QPF, this system will bring its heaviest rain, just over a half inch, to the areas that receive less rain from the cold front today.
High pressure will slowly sink South across the region Today as a weakening front approaches from the Northwest. The above normal temperatures will continue Today, with readings reaching the lower 80s in most places, except a little cooler at the beaches.
Clouds are expected to fill back in overnight ahead of a cold front expected for Friday with overnight temperatures well above normal. A progressive system in the central CONUS will move east, eventually dropping a cold front south Friday into Friday night. The trough associated with this system is not amplified and the dynamics look fairly weak well north of the region. On Saturday, rain chances will be high across north Georgia as a weakening cold front works its way southward.
Dry conditions with warmer temperatures will then prevail Saturday. Further north there was a weak upper level trof that extended from southern California to west of northern Baja California. This disturbance will be directed toward southeast Arizona by the above mentioned trof during the overnight hours into Friday afternoon bringing another shot of widespread rain.
1105 PM CST Thu Feb 15 2018 A strong surface cold front continues to drop south across South Dakota, bringing gusty northwest winds along with it.
Surface wise, a large, albeit weakening ridge is centered over central Florida and the adjacent Atlantic and Gulf waters. A deep troposheric, east-west oriented ridge axis extending across south Florida and the adjacent Gulf and Atlantic waters and the adjacent Gulf and the Atlantic Ocean before lifting into central Florida by the end of this weekend. High temperatures will average in the lower 80s with overnight lows climbing into the lower to mid 70s. The large and deep ridge axis will meander but remain draped across the southeast United States and the northern half of the Florida peninsula through the period. Little change in above normal temperatures with daytime highs mainly in the lower 80s and overnight lows in the mid 70s.
Near the surface, high pressure is sinking southeast across the Dakotas into the Central Plains. An attendant surface cold front is sliding south across Southwestern Kansas this afternoon. Behind the cold front, Canadian high surface pressure will quickly move in from Montana. Southerly flow returns late Friday afternoon as the aforementioned high pressure moves east.
347 AM CST Fri Feb 16 2018 09z/3am surface map shows a cold front along the Ohio River. to the lower 40s south of I-70.
A band of persistent flurries/snow may even develop across north-central Kansas along the base of the trough moving through the area. These gusty winds may also lead to near-critical fire weather conditions across parts of Kansas where relative humidity values drop into the low 20s.
1118 PM CST Thu Feb 15 2018 Cold front has almost moved through the CWA and is still going through parts of southeast IL, where rain continues to fall. Looks like the warm front made it about as far north as a Macomb to Peoria to Chenoa line today, with the fog still lingering to the north early this afternoon.
354 AM EST Fri Feb 16 2018 Rain will taper off today, as a cold front exits the region. Dry weather will return tonight and Saturday morning as high pressure slides east across the region. Similar to last night, models continue to struggle with low pressure and a cold front moving up the coast Saturday afternoon and night.
1258 AM EST Fri Feb 16 2018 High pressure will remain over the western Atlantic through Friday.
421 AM EST Fri Feb 16 2018 It will be breezy and warm ahead of an approaching cold front today.
Temperatures south of there are in the 60s and 70s, with a few readings even in the lower 80s in the St. High pressure over the Ohio Valley Friday night will continue a return flow over the region. While deep moisture will be lacking, there could be enough to generate some light snow along a cold front late Friday night and Saturday morning from eastern Minnesota into WI.
329 AM EST Fri Feb 16 2018 It will be breezy and warm ahead of an approaching cold front today.
A cold front will drop through the area tonight, bringing continued opportunity for rainfall and perhaps a rumble of thunder or two to the area. High pressure will provide a brief dry period before precipitation chances return Saturday into Saturday evening as an upper level disturbance pushes through the area. Right behind the cold front (currently across the far northwest forecast area), there is a thin area of fog with visibility below 2 miles. Dry weather will be the rule Friday afternoon into Friday night, before another low pressure system moves through the region Saturday into Saturday evening. Consensus temperatures were generally acceptable outside of Friday, when highs should be not much warmer than overnight lows tonight, and temperatures will likely be slowly falling much of the day as cold advection is ongoing.
1209 AM EST Fri Feb 16 2018 A small area of low pressure will track north of the area tonight. A cold front will cross the region on Friday. High pressure will approach Friday night and pass south of the state on Saturday. Low pressure tracking through Quebec will bring a mild night tonight with lows in the low 30s across most of the region. A cold front will approach early Friday and push across the area around midday. Cold advection can be expected in the wake of the cold front Friday night. Winds will tend to diminish toward Saturday morning as the high builds across. Saturday will feature abundant sunshine as extensive high pressure builds to our south.
The warmer air will be fleeting with steady low- level cold advection tonight behind a cold front working southward. A bit of light snow is possible this evening as the upper trough axis swings through, although lift isn't very impressive, so maintained 20-30 pops for now. High pressure will build southward from the northern plains later tonight with sunny skies expected on Friday. An upper level trough and associated weak cold front will move across the area on Saturday with a chance for light snow.
Could see a brief wintry mix over far Nrn AR early Sat mrng, but no impacts are expected as air temps are fcst to rmn abv freezing.
1232 AM EST Fri Feb 16 2018 Rain will taper off today, as a cold front exits the region. Left in the mention of heavy rain ahead of the cold front for the rest of the night as well. Dry weather will return tonight and Saturday morning as high pressure slides east across the region. Similar to last night, models continue to struggle with low pressure and a cold front moving up the coast Saturday afternoon and night.
Warm and dry weather are forecast Friday and Saturday as a ridge of high pressure builds into our region.
High temperatures this afternoon will only reach the lower to middle 30s.
The cold front has already moved south of KGUY/KDHT with northerly winds of 20-25 kts. /Issued 220 PM CST Thu Feb 15 2018/ A cold front which lies from southeast Colorado into eastern Wisconsin will continue to push south. However, an upper level short wave trough will move northeast in the southern jet stream and it is expected to bring precipitation mainly to the south of the Texas Panhandle on Friday night.
358 AM CST Fri Feb 16 2018 Upper level trough from MAN/Ontario border to northern MN will continue to move east. Upper level trough over the BC coast will move across southern MAN Fri night. Cold front will move in Fri night. With the cold front, will have low pops over parts of the MN side for Fri night. A cold front will be pushing through the area on Saturday. along with an upper trough.
Winds will shift to the SW and increase to 10-15 knots in advance of a cold front approaching the region.
The next, stronger system remains slated to arrive on Saturday as a trough impacts the area.
Ridge axis further south today brings more SSW flow initially. A broad area of high pressure will continue to bring dry conditions to South Florida tonight.
A broad upper level ridge covering the GOMEX will flatten to nearly zonal flow along the gulf coastal states Friday through the remainder of the period. This will allow a weak cold front to drop down from the north. Temperatures will remain well above normal for mid-February with highs around 80 to the lower 80s inland and upper 70s along the coast.
817 PM PST Thu Feb 15 2018 A cold front will exit to the south this afternoon ushering in dry, warm, and sunny conditions through the weekend. Gusty north winds will be spotty overnight then be confined into the lower Colorado River Valley Friday. Trough and associated cold front will continue moving southeastward, exiting the area later this afternoon. Isolated, light shower activity will continue to develop across Mohave County over the next 1-3 hours before the cold front pushes out any lingering available moisture and cloud cover. Temps will remain unchanged through tomorrow before jumping 5-10 degrees warmer for Saturday.
This cooler air then settles in for the beginning of the weekend. That means next pcpn chance, slated for Friday night-Saturday morning onset, could encounter critical crossover temps for freezing/frozen pcpn with potential for light accums. However, quick turn around to southerlies Saturday, and some model (nam) indications for later onset and warm nose means lower LSR ratios (collaborated with LSX/SGF on this edit) and shorter window for freezing/frozen early Sat morning will spell mainly just a few tenths snow accums possible mainly SEMO highlands, washed out quickly by southerlies/rain/temps in 40s Saturday pm. High Pressure will move east of the WFO PAH forecast, allowing for a return flow of moisture into the area.
Expect highs pushing the lower to mid 40s(F) this afternoon with the warmer temperatures in extreme southwest Kansas, particularly if enough sunshine breaks out. Look for lows down into the 20s(F) across central Kansas Friday night with the lower to mid 30s(F) likely in extreme southwest Kansas. Southerly flow returns late Friday afternoon as the aforementioned high pressure moves east.
1131 PM CST Thu Feb 15 2018 An approaching cold front will allow for southwest winds up to 10 knots overnight. However, a cold front is surging south into Northern Oklahoma and should be very close to the Interstate 30 corridor around sunrise.
A cold upper trough will move out of Utah tonight. A weak trough will clip far northern Utah Friday night. A warmer westerly flow will be over the area on Saturday.
343 AM CST Fri Feb 16 2018 A cold front was moving southward early this morning and will likely have moved through the rest of the CWA before sunrise. However, this will gradually transition to rain as the low levels warm thru the morning. Precip chances diminish fairly quickly during the afternoon hours as the trof passes to the east. With sly to swly flow at low levels on Sat and even more so on Sun, have trended twd the warmer guidance, especially on Sun. This front is expected to very slowly move south until the upper trof finally pushes it south of the CWA by Wed morning. For now, have trended twd a compromise for Tues, then twd cooler guidance for Wed. Tilly The cold front has passed south of I-70 and is now near the I-44 corridor.
A low pressure system will approach the two state area and increase mid and high level clouds. Meanwhile minor changes were done to weather and temps that are expected to fall into the 30s across the basin except in the 20s across the higher locations. a low pressure system will increase clouds and most taf sites except for kykm may approach lcl mvfr conditions with lowering ceilings in and near showers after 12z.
Tonight and Friday Cold front moving across the region may be followed by some snow showers of flurries tonight.
The low clouds will be slow to improve this morning. An upper level ridge over the Gulf of Mexico will weaken today while at the surface, a cold front pushes into the southeast, with the front weakening as it pushes southward.
313 AM CST Fri Feb 16 2018 06Z surface data has the cold front from northern Ohio into Oklahoma with high pressure over the Plains. Tonight, quiet and dry conditions will be seen as high pressure quickly moves through the Midwest. First, light snow chances with warm frontal passage Saturday. warmer with highs into the 30s to around 40F south with flurries and chance of light snow, mostly north with any amounts likely less than an inch suggested until mid afternoon then clearing.
Breezy to windy conditions are expected to return to the OK and TX Panhandles on Monday in advance of a cold front and an approaching upper level storm system.
315 PM EDT Sun Mar 25 2018 Low pressure just off the Carolina coast will shift east and further offshore through tonight.
High pressure to the north will build over the area Monday with breezy northeast winds and considerable cloudiness with isolated to scattered showers, so a different kind of weather day than today. Max temps will be noticeably cooler along the Volusia coast in the lower 70s and upper 70s metro Orlando.
The upper level pattern is starting to transition to southwesterly flow over Texas as a trough digs down along the west coast.
343 PM EDT Sun Mar 25 2018 High pressure will continue to dominate the weather across South Florida bringing another night of dry conditions. On Monday, an area of low pressure located in the Atlantic waters east of the Carolinas will strengthen and the cold front associated with it will push through South Florida as a back door cold front on Monday night.
154 PM EDT Sun Mar 25 2018 High pressure will allow for dry conditions across the region today. High pressure and dry conditions will be in place for the near term. At the surface, a warm front will lift across the region on Monday night.
Some energy on the back side of a cold upper trough continues to move through the area this afternoon, resulting in isolated to scattered showers. Tonight will be cold again for most areas with the potential for temperatures to drop below freezing in the west side valleys, particularly the Rogue/Illinois. That disturbance will ride over the top of a building eastern Pacific ridge and this could graze NW portions of the area (mainly NW of the Umpqua Divide) with some light precipitation Monday.
306 PM EDT Sun Mar 25 2018 A trough of low pressure swings across the Eastern Shore through early evening. High pressure builds in from the north through mid week with moderating temperatures. The next cold front is expected late in the week. The latest sfc analysis shows 1037mb high pressure over Quebec, Canada nudging south through the Mid-Atlantic region, with an area of low pressure now well off the Carolina coast. Highs Monday from the 40s on the Eastern Shore to the low 50s inland.
238 PM EDT Sun Mar 25 2018 An upper level trough over the northeast conus will lift out to the east on Monday, as ridging builds in from the Great Lakes. A slow moving cold front will likely push through the region during the second half of the week. Large scale subsidence has overspread the region as of mid afternoon, slapping down the earlier instability which created locally heavy snow showers over parts of the Lower Susq River Valley during the midday hours.
400 PM CDT Sun Mar 25 2018 Latest UA analysis and WV imagery shows modest ridging over the region while an upper trough is currently crossing the western US. This will keep warmer than normal conditions over the area the next couple of days with lows in the 60s and highs around 80s. The pattern aloft will amplify early this week between a ridge over the eastern CONUS and the trough over the west. The trough is progged to deepen and become positively tilted over AZ/western NM, moving very slowly to the east through the middle of the week.
After lows in the mid/upper 60s tonight, high temperatures should climb into the lower/mid 80s (inland) tomorrow afternoon.
