248 AM CST Thu Feb 15 2018 Warm temperatures will be the name of the game today out ahead of a cold front that will move through the region later this afternoon. That said, warm front over our region this morning will not totally clear the CWA before the cold front arrives later today, meaning there should be a pretty healthy temperature gradient across our region.
Snow will continue to fall over the higher mtns today as moist winds are lifted up the facing slopes. Otherwise a cold front will drop south across the CWA with temperatures falling behind it later this morning and afternoon.
228 AM EST Thu Feb 15 2018 A weak trough of low pressure and its accompanying rain will exit the coast early today.
1025 PM MST Wed Feb 14 2018 Upper level analysis has near zonal flow across the northern Plains, with a trof along the CA coast. At the surface, high pressure resides across the central Plains with weak lee trof along the northern Rockies. Clouds will continue to increase from the north and west this evening as the next cold front slides south across MT and ND. System clears the area Thursday evening with Arctic high pressure sliding across the Black Hills.
High temperatures right around 80 degrees are expected, though sea breeze development will keep coastal locations cooler. With light winds and plenty of moisture available in the lower levels, another night of fog and stratus is expected tonight.
A cold front will be slowly approaching the region from the north today. By tonight, the cold front will move into the forecast area with a better chance of showers moving through.
A cold front will push through during the late afternoon, but increasing southwest winds and hopefully a bit of sunshine will help temperatures rise into the 60s to near 70 degrees by the time the front passes.
Some light drizzle/rain possible after midnight mainly across the north in slightly closer proximity to the low level jet in this extremely warm and moist airmass.
Lee trough will move farther e today, probably even e of MAF by 00Z. Despite high clouds it will again be warm today along and e of trough, 15-20 degrees above normal. Thereafter a strong cold front will move thru plains early Fri AM and as said jet moves ewd precip is expected to renew across the far wrn CWFA around 15Z-18Z Fri and then expand e, but a narrow axis INVOF RRQ of jet and secondary jet approaching from the sw. Much cooler still looks to be a good be on Fri. A cold front may bisect the NE CWFA Tue from around a Lamesa-Big Spring, thus mostly above normal temps s of the front Tue.
Most of the precip will be lifting northward today through this evening as cold front takes shape to the north.
347 AM EST Thu Feb 15 2018 Low pressure will track to our north today.
Expect very warm temperatures Thursday, with highs as warm as the mid 80s for parts of the Big Country, and into the lower 80s for the Concho Valley.
334 AM EST Thu Feb 15 2018 The Aviation section has been updated below A cold front will drop southeast across central Indiana Thursday night.
1035 PM MST Wed Feb 14 2018 With reports of 3 inches coming in across the high valleys north of the Snowy Range already, decided to issue a Winter Weather Advisory for the upper North Platte River valley, including Saratoga, and the northern Snowy Range foothills until 8 AM Thursday morning.
High temperatures today will range from the lower to middle 40s north of the low track around Galesburg and Lacon. As the low tracks into the southern Great Lakes, it will drag a cold front through the area tonight.
Good south to southwest flow in the lower levels and broad area of southwest flow aloft. Much warmer 850 mb air is advecting into the area with this trend expected to continue into tonight. With the warm start to the day on Thursday, we are looking at temperatures getting into the low to mid 70s across the area. A cold front is expected to begin pushing into the area Thursday evening.
The upper pattern remains zonal to some ridging, as temperatures will warm into Thursday.
331 AM CST Thu Feb 15 2018 Currently, an upper level longwave trough extended from the Hudson Bay Low southwestward across the Canadian prairies to the Desert Southwest. Widespread light snow continued along the upper level trough and mainly along and north of the surface cold front. The upper level longwave trough is forecast to move southeast across the Northern Plains today and tonight.
1133 PM CST Wed Feb 14 2018 At 1 PM, high pressure was centered over the Carolinas and a cold front was located over Montana. The increase from the northwest is due to an approaching cold front. Meanwhile, the increase in the clouds from the south is due to a short wave trough moving northeast the Mid Mississippi River Valley. During the remainder of the morning and early afternoon, a cold front will move through the region. This frontal passage looks to be delayed some, so bumped up the high temperatures anywhere from 2 to 5F. The upper level trough axis swings through Thursday night with models indicating sufficient forcing for some light snow through the evening, but with minimal accumulations.
This Clipper will bring a cold front through the Northland tonight and early Thursday and a period of light snow. Gusty north-northwest winds will develop in the wake of the cold front and continue through the day Thursday. Northwest Wisconsin should manage to reach highs in the low 30s, but it will be much colder up in north-central Minnesota with highs up there only reaching the middle teens. Chances of precipitation should be winding down Thursday evening as the remnants of the cold front that will move through tonight moves out of northwest Wisconsin.
354 AM CST Thu Feb 15 2018 An area of low pressure and Arctic front will cross the region today.
conditions are forecast to lift back to VFR with scattered MVFR ceilings remaining into the afternoon hours ahead of a cold front expected to move into Northeast Oklahoma and far Northwest Arkansas late in the TAF period.
314 AM CST Thu Feb 15 2018 An anomalous 500mb subtropical ridge will be prevalent through the forecast period, leading to temperatures and dewpoints well above normal for this time of year. For today, the ridge will be centered over the Gulf of Mexico with 500mb heights up to 588dm in our forecast area.
Showers will not likely make it much farther south before the trough axis shifts east of the forecast area after about midnight. Temperatures this evening running similar to 24 hours ago most stations with warmer minimums expected northern Sacramento valley due to winds.
256 AM EST Thu Feb 15 2018 Low pressure will track to our north today.
328 AM EST Thu Feb 15 2018 A cold front will drop southeast across central Indiana Thursday night.
The remnant of the coastal California low pressure system will race east along the Arizona border tonight. The next upper level trough will move into Utah from the Pacific Northwest late tonight into Thursday. This trough will bring colder temperatures and occasional snow to northern and western Utah through the day Thursday.
This will come crashing to a halt as a cold front drops south tonight. As the center of a high pressure moves south of the region, winds back towards the west but remain breezy. This wind should prevent maximum radiational cooling despite clear skies from ridging aloft within a cold air mass Thursday night.
1231 AM CST Thu Feb 15 2018 Arctic cold front had pushed through the I-94 corridor before midnight. This lowered amounts to generally 1-2 inches along and north of the Hwy 200 corridor. Current surface analysis places low near Winnipeg, with cold front stretching off to the west near the international border. Upper level analysis places trough stretching from northern Manitoba towards the Pacific northwest, with potent wave sliding across the Canadian plains into the northern plains. For the rest of this afternoon into this evening, cold front will continue to settle to the south with snow gradually developing from north to south.
107 AM EST Thu Feb 15 2018 A weak disturbance will keep light rain chances through this morning before low pressure and a cold front results in widespread rain later today and tonight.
cloud cover to remain cross the area as the region lies just north and west of a front/trough combo.
1249 AM EST Thu Feb 15 2018 High pressure will remain south of the area overnight.
Winds will taper late Thursday, then begin veering to the northwest in advance of a cold front expected late tomorrow night. A closed low just off the southern California coast this afternoon will open up and move eastward over the desert Southwest. Additional short wave energy will dive into the trough and keep it nearly stationary through the weekend with a series of short wave troughs ejecting from the trough across the southern High Plains.
334 AM EST Thu Feb 15 2018 A weak trough of low pressure and its accompanying rain will exit the coast early today.
307 AM CST Thu Feb 15 2018 Strong troughing across the western United States early this morning with an increasing upper level jet from the southern into the central Plains. Went ahead and increased pops and qpf for this event with the highest amounts near highway 14.
241 AM EST Thu Feb 15 2018 A weak trough of low pressure and its accompanying rain will exit the coast early today.
A series of mid and upper-level waves in the northern stream will sharpen and drive a cold front into the Ohio Valley late tonight. Tonight the cold front will drop into southern Indiana, ramping up the coverage and especially the intensity of precip.
Skies will start clear this evening but increasing low level moisture may produce low clouds later tonight through early Thursday, especially across the higher terrain in central and northcentral Wisconsin, and perhaps near the lake. A cold front will arrive in the north in the afternoon, where it could bring some light snow or flurries.
Temperatures ranged from the middle 20s across the international border region, to the lower to middle 30s in southern portions of the CWA. Meanwhile, a cold front was dropping southward across the Northland this morning. For today, the cold front will continue to drop southward across the region. High pressure will then build in tonight, with much colder temperatures expected across the Northland.
Later tonight, a cold front will approach from the north, forcing some showers and even a clap of thunder or two.
Chances will increase from north to south this afternoon into this evening with the approach of a cold front.
At the surface, a marine warm front across north central Mississippi will slowly lift north through the night. In addition, areas of fog can be expected especially just to the north of the lifting marine warm front.
An upper trough and additional weather systems will keep the weather cool and showery into the middle of the week. A big change in the weather today as a cold front brought measurable rain to the region. The air mass will remain cool, moist and unstable through Monday as an upper level low moves over the Pac NW. The cooler air mass will keep temps in the 50s to lower 60s. Models are showing an increase in lift and moisture with a trough axis Monday night.
750 PM EDT Sun Sep 17 2017 A weakening cold front will move into the area tonight into Monday, becoming stationary by Monday night.
20z sfc analysis shows relative high pressure through the area and this is keeping the shower threat at bay while some activity is noted well to the west. Temperatures did get up to the low 80s most places, just above normals and the earlier guidance. Meanwhile, with light northerly winds, dewpoints are generally in the lower 60s. They all depict a weakening ridge over the southeast part of the nation. Given the model symmetry will favor a blended solution with a lean toward the higher resolution CAMs and a good bit of persistence - especially at night. Again used the CONSShort and ShortBlend as the starting point of all the grids making some adjustments to the temperature ones each night based on terrain in anticipation of small to moderate ridge and valley splits.
update aviation An upper level trof of low pressure will approach the region on Monday.
/26/ PW values were approaching an inch and a quarter and the wind profile was pretty light in the lower atmosphere so stationary heavy downpours are likely. The boundary/upper trough axis may be the focus for some thunderstorm activity. Broad ridging early in the week should give way to some troughing, which could actually increase chances for rain and storms later in the week before another ridge builds back in.
Temperatures will be cooler tonight than the last couple nights, with lows right around normal for mid-September.
A cold front, locked within a large stnry upper low over the western states, will remain stretched across central plains.
With deepening surface trof will see an increased west to southwest wind tonight that will help hold temperatures up and prevent fog development. Dry weather continues on Monday for the bulk of the CWA out ahead of an upper Pacific trough and surface cold front. The Pacific trough will move eastward on Monday, with showers and isolated thunderstorms possible first in our western areas late Monday afternoon. Then the cold front associated with the trof will bring a good chance of showers along with some frontal wind across the area Monday night.
911 PM CDT Sun Sep 17 2017 Skies are mostly clear across the forecast area this evening with temperatures ranging from the lower 70s to lower 80s. Temperatures ranged from the mid 80s to the low 90s. Less activity will be seen across the far southeast where the upper level ridge axis will pass overhead.
An upper level ridge extending from the northeast gulf northward to the Ohio River Valley will shift slightly eastward over the region through the near term.
/issued 345 PM CDT Sun Sep 17 2017/ Mid-afternoon sfc analysis shows high pressure centered over the sern CONUS remaining in control of our region with local 88D VWP products showing a light onshore low/mid-level flow in place. Water vapor imagery shows ridging in place from nrn Mexico through the wrn Gulf region to the mid-South. Higher up, next storm system crossing the wrn CONUS should help flatten the ridging aloft, providing a little relief to the mid-level capping. Light and mostly onshore flow should continue through the period with high pressure remaining anchored to our east or northeast.
559 PM MDT Sun Sep 17 2017 Early afternoon water vapor loop showed the upper trough axis entering western WY and northern UT. Scattered showers and thunderstorms will taper off from west to east later this evening across the plains as the upper trough moves through the CWA.
/27/ Prior discussion below: PW values were approaching an inch and a quarter and the wind profile was pretty light in the lower atmosphere so stationary heavy downpours are likely. The boundary/upper trough axis may be the focus for some thunderstorm activity. Broad ridging early in the week should give way to some troughing, which could actually increase chances for rain and storms later in the week before another ridge builds back in.
Overnight rainfall followed by a day of cloud cover has helped keep the cooler airmass in place, with the office just hitting 70 over the past hour. Of note for convection potential are a weak wave over Western Kansas, with stronger convection along the high plains east of the Rockies.
/issued 306 PM CDT Sun Sep 17 2017/ SHORT TERM (Tonight through Monday Night): 500mb ridge across the western Gulf of Mexico and south Texas will provide subsidence across the CWA in general tonight into Monday. isolated showers and thunderstorms will develop across the coastal sections of the CWA Monday as the seabreeze front develops along the lower Texas coast and moves inland.
803 PM EDT Sun Sep 17 2017 Weak high pressure centered over the Northeast will extend south down the Appalachians into the Mid Atlantic through Monday.
/issued 150 PM CDT Sun Sep 17 2017/ Upper trough extends southward across the Intermountain West as a ridge extends northward from the Gulf up across OH. The ridge will get flattened out as the trough moves east but it will be reinforced by additional troughs moving down over the NW.
930 PM PDT Sun Sep 17 2017 A trough of low pressure will maintain below average high temperatures today, partly to mostly cloudy skies in the coast and valleys due to a deep marine layer, and gusty west winds in the mountains and deserts. A little warmer on Monday as low pressure weakens.
813 PM EDT Sun Sep 17 2017 Another quiet evening as convection is held to a minimum by high pressure. /issued 356 PM EDT Sun Sep 17 2017/ South Florida sits between the counterclockwise flow around Hurricane Jose and clockwise flow from high pressure over the Gulf are providing a somewhat unseasonal northerly flow across the area. The pattern will shift slightly as Jose moves north and the high shifts slightly further west. A mid-level trough extending offshore of South Florida from Jose could allow for some convection tomorrow, particularly along the coast in the morning.
Cold advection will cease later this evening with the core of high pressure to track from the Middle Mo River Valley to nrn WI.
The upper low over southern Canada continues to move slowly off to the northeast. The clearing trend should continue into this evening as the low pressure system pulls further away from the area and diurnal cu dissipates. With the south fetch to the winds and at least some sunshine tomorrow, highs will be near the 70 mark across the west but slightly cooler in the eastern counties. A mild and breezy Monday evening is expected with overnight lows in the low 50s and southeasterly winds under mostly clear skies.
520 PM MDT Sun Sep 17 2017 Water vapor images showed a trough over central MT/WY moving toward the CWA. Monday will be dry and warmer than today as the 850-mb temperatures rise to the lower 20s Celsius.
/Tonight through Monday/ High pressure is moving across Iowa today after precipitation passed across the region last night. The high pressure brought dry air back to the state along with mostly clear skies except for the far south. The area of high pressure will continue to slide east overnight. Strong return flow will develop in the wake of the high pressure and in advance of a vigorous short wave approaching from the west.
1153 PM CDT Sun Sep 17 2017 High pressure moving east across the area this afternoon producing mostly sunny skies with cooler/pleasant temperatures ranging from the middle 60s to a few lower 70s. High pressure will slip off to the east tonight as a mid-level trough ejects northeast out of the Central Plains. Scattered showers will then spread northeast across the area for Monday as that mid-level trough tracks northeast into the Upper Mississippi River Valley. Scattered showers/cloud cover will keep temperatures on the cooler side with highs in the 60s to near 70. Scattered showers will linger into Monday evening, tapering off after midnight as that mid-level trough exits east. Although there is fairly broad/weak warm air advection and isentropic lift ahead of low pressure moving into the Northern Plains, NAM bufkit sounding keeps things dry.
Kept temps down a bit as obs have trended cooler than models the past few nights.
An 850mb cold front extended from a now in western ON through the mid-MS river valley and toward the TX/OK panhandles, with much of the moisture shunted ahead of it.
549 PM MDT Sun Sep 17 2017 As on weak trough exist the region to the east, carrying some remnant showers with it, drier westerly flow with another weak embedded trough will pass over the area this evening. Almost nothing in the way of precipitation is expected from this second trough, just some mid and hi cloud over the northern half of the area. Monday should see dry westerly flow aloft and warmer temperatures from abundant sunshine, followed by a cool clear night.
The story of the rest of the week will be upper ridging and isolated showers and storms mainly during the afternoon. GFS and Euro have the upper high strengthening to our north late in the week which could reduce pop chances for the weekend.
High pressure continues over the region with light winds overnight.
933 PM EDT Sun Sep 17 2017 Weak high pressure centered over the Northeast will extend south down the Appalachians into the Mid Atlantic through Monday.
The surface cold front will remain deep into the panhandles this afternoon, but begin to turn back north as a warm front by later this evening. Lows for early Monday do not look to be much warmer despite warm advection, however may be noticeably warmer in the southeast sections. The warm front will help scour out the low level moisture, bringing full insolation back and a bump back into the mid and upper 80s Monday afternoon.
Cold front that moved through this morning and brought the rain and some thunderstorms late last night reaches the lower Great Lakes on Monday while high pressure over the plains builds across the Upper Great Lakes. Gusty northwest winds this aftn (leading to a high swim risk on Lk Superior beaches of Alger county) will diminish as the high moves closer tonight and with pwats down to 0. Lows in the favored cold spots could drop to or just above freezing so those with any sensitive plants should cover those or bring those in if possible.
850 PM MDT Sun Sep 17 2017 Upper trof will move across Colorado tonight but most of the convection has diminished except for main band moving into Nebraska panhandle and clipping the border areas of Northern Colorado.
Kept temps down a bit as obs have trended cooler than models the past few nights. Weak high pressure remains entrenched across the region, so we can expect relatively benign weather and generally light winds the next 24 hours & beyond.
404 PM PDT Sun Sep 17 2017 Cold front currently approaching the area will bring a slight chance of rain to our northern areas. Showers and cooler temperatures will persist through the week due to an upper level trough.
946 PM EDT Sun Sep 17 2017 A weakening cold front will move into the area tonight into Monday, becoming stationary by Monday night.
1028 PM EDT Sun Sep 17 2017 High pressure will remain in control of the weather pattern across northeast Georgia and the Carolinas through much of the week, leading to above normal temperatures and below normal precipitation chances.
729 PM EDT Sun Sep 17 2017 There is a chance of showers and a few thunderstorms tonight as a cold front slowly approaches the area.
Highs in the upper 80s to around 90 and lows in the low to mid 70s.
834 PM EDT Sun Sep 17 2017 Weak low pressure in the upper atmosphere will keep a slight threat of afternoon showers around the region through Monday.
Tonight and Monday Showers exited Wisconsin as a cold front pushed east of the state. Monday Night Through Sunday Temperatures will warm through the work week with mid level ridging and height rises bring warmer temperatures to the western Great Lakes.
Britton An upper level trof of low pressure will approach the region on Monday.
/issued 342 PM CDT Sun Sep 17 2017/ (Tonight and Monday) Southwest flow aloft will continue across West Central Texas as the 500mb ridge remains in place along the southern Gulf Coast. Early morning cloudiness will give way to mostly sunny skies and temperatures will climb into the low to mid 90s.
Early afternoon water vapor loop showed the upper trough axis entering western WY and northern UT. Scattered showers and thunderstorms will taper off from west to east later this evening across the plains as the upper trough moves through the CWA.
753 PM EDT Sun Sep 17 2017 A weak cold front will approach the region tonight and stall in western Ohio on Monday and weaken.
953 PM EDT Sun Sep 17 2017 High pressure will bring patchy fog again tonight and sunny and warm weather on Monday.
