741 PM EST Fri Feb 2 2018 Latest surface analysis places the approaching cold front across central Florida just north of the Lake Okeechobee region. Winds will be shifting between northwest to northwesterly flow this evening with a cold front passage before settling into a mainly easterly- northeasterly flow on Saturday. High temperatures today were in the mid to upper 70s with a few areas reaching into the low 80s today. Mostly sunny skies have turned to partly cloudy skies ahead of a cold front. Latest surface analysis has the cold front draped across northern/central Florida working its way down the peninsula. This cold front will not be like the past few we have seen reach South Florida.
The sounding this evening still has northeast winds from the sfc to 850 mb from the cold front that moved through this morning. /issued 355 PM CST Fri Feb 2 2018/ A period of unsettled weather is in store for the lower Mississippi Valley area this week as a series of upper level disturbances and associated frontal systems move through the area. There could be some brief periods of heavy rain along with some embedded thunderstorms as the upper level disturbance interacts with a warm front that will be in the area Saturday night.
/issued 230 PM CST Fri Feb 2 2018/ Ahead of a shallow trough arriving in NW flow tomorrow afternoon, southerly winds will slowly moisten overnight but should fall short of generating low clouds or advection fog.
640 PM CST Fri Feb 2 2018 Stratus clouds continue to expand north and east across the area this afternoon ahead of an approaching warm front. Saturday the inverted trough noses into Iowa and southern Wisconsin.
Mild and dry conditions are expected across the region during the next 7 days as high pressure dominates the weather pattern. Water vapor imagery as of early this afternoon showed broad ridging across the eastern Pacific Ocean with generally moist, onshore flow directed towards the Pacific Northwest. Over the next 7 days, the ridge of high pressure will essentially dominate the weather pattern for northwest California and prolong dry and mild conditions.
204 PM PST Fri Feb 2 2018 A prolonged period of high pressure will likely continue through mid-month and will continue a persistent pattern of unseasonable warmth, dry conditions and generally light winds. Ridge of high pressure remains through the weekend with mostly sunny conditions, light winds and unseasonably warm temperatures.
902 PM EST Fri Feb 2 2018 A cold night will be followed by warmer and dry weather for Saturday.
Models keep moderately strong westerly flow aloft overnight, then a weak upper trough moves across Saturday morning. Will go with likely or better pops in the high mountains the first two periods.

633 PM EST Fri Feb 2 2018 High pressure will build across the region offering dry conditions into Saturday.
957 PM EST Fri Feb 2 2018 High pressure will build across the region offering dry conditions into Saturday.
623 PM EST Fri Feb 2 2018 High pressure along with cooler and drier air overspreading the region through Saturday.
900 PM CST Fri Feb 2 2018 Wx map shows high pressure continuing to build southward, with the pressure gradient beginning to relax inland. Northeast winds will continue to diminish this evening, become more easterly by daybreak, and southeasterly as the high shifts east and low pressure moves through the Central Plains.
Surface wise, a formidable and expansive area of high pressure (1034 mb) is centered over Kentucky with a ridge reaching down the Sunshine State.
another short wave is moving over the top of the upper level ridge centered offshore.
/issued 234 PM CST Fri Feb 2 2018/ Upper pattern has a broad trough over the Eastern part of the country with a ridge over the Western US.
Some model guidance showed higher QPF/snow amounts but it seems it could be a battle between decent lift associated with the jet and practically moist adiabatic sounding profiles and slightly warmer than desired 700mb temperatures. Models keep moderately strong westerly flow aloft overnight, then a weak upper trough moves across Saturday morning. Will go with likely or better pops in the high mountains the first two periods.
Our post cold front air mass will be moist enough to perpetuate a low stratus deck well into Saturday morning for the Spokane, Coeur d'Alene, and Pullman airports. The redevelopment of gusty winds and daytime warming on Saturday should erode the low cloud deck at our TAF sites.
but it is possible many spots in NE ND are on the lower end of current fcst range (2-3). Surface ridging will build into the region overnight allowing temperatures to drop into the teens and twenties below zero.
High pressure will move over the region this evening on its way to the Mid Atlantic coast Saturday afternoon. The return flow on the back side should bring us warmer temperatures in the afternoon, after another cold start in the teens Saturday morning. Southerly winds that night will keep us from cooling down too much and forecast soundings hover around the freezing mark through a fairly deep layer.
Pressure gradient between high pressure over Appalachia and low pressure south of Cuba will keep tight pressure gradient. Lows will be near freezing to the mid 30s across inland southeast Georgia, and the mid to upper 30s across most of inland northeast Florida. Lows will remain warmer along the coast due to the onshore flow, with temperatures in the 40s. High pressure will progress eastward, moving offshore of the Mid-Atlantic coast by Saturday evening.
339 PM MST Fri Feb 2 2018 Main focus will be on winds in the wind prone areas as well as the expected heavy snowfall over the higher mtns through Saturday.
902 PM CST Fri Feb 2 2018 Skies are mostly clear this evening across the forecast area with temperatures ranging from the lower 20s to lower 30s. ranging from near 30F in the north to the low 40s in the far southeast. clouds will be on the increase later tonight along with warmer temperatures tomorrow. A few embedded elevated storms may also occur later in the night across the south as showalter indices drop to 0C in the trough axis.
Updated forecast for warmer low temperatures tonight and patch fog in the valleys.
1035 PM EST Fri Feb 2 2018 High pressure will build into the state overnight and Saturday.
717 PM EST Fri Feb 2 2018 The front will continue to push through the area overnight and stall across south FL as high pressure builds into the area for Saturday.
For now, model blend suggests freezing rain will primarily be limited to NW SD beginning around 12z. However, short-term guidance indicates that we may have some freezing rain at onset (04-06z) across our NW thanks to fairly warm 850 mb temps. Upper ridging remain just off the Pacific Coast with deep northwest flow across the northern Plains. Models are indicating some precip may switch over to freezing rain across northwest SD as 850 mb temps of 0 to +3C push in late tonight with sub-freezing surface temps persisting.
A strong upper ridge just off the west coast remains in control with dry weather and above normal temperatures.
444 PM CST Fri Feb 2 2018 High pressure now over the Ozarks will shift to the east tonight. A cold front will move through the area Saturday night and bring the potential for some light rain or a mix of rain and snow to areas of the eastern Ozarks.

610 PM EST Fri Feb 2 2018 High pressure through Saturday.
The upper trough over the Northern Plains continues to drop south across Lake Superior and Wisconsin tonight, with southern Wisconsin getting into the entrance region of the 115 knot 250 mb jet later tonight. Cold air advection will be occurring today behind the cold front.
343 PM EDT Fri Jun 23 2017 Currently - A surface Atlatnic ridge extends across the Florida peninsula, resulting in gentle to moderate east to southeast breezes across the Florida Keys and surrounding waters. Ridging aloft will hold keeping rain chances slight.
1242 PM CDT Fri Jun 23 2017 A cold front will shift south across the region overnight. Otherwise, an approaching cold front will be our next weather maker tonight/overnight.
Dry weather will continue into Saturday with an upper ridge building across the Pacific coast and gradually translating east, leaving NE Montana in northwest upper flow. This eastward moving Pacific feature will lead to rising heights over the Northern High Plains and somewhat warmer temperatures on Saturday as well, but much of the warming will hold off until just beyond the short term period.
249 PM CDT Fri Jun 23 2017 Cool and breezy conditions will continue into Saturday as an upper trough sits over the region. The upper flow through the next few days will be mainly northwesterly with a trough to the east and a slowly eastward migrating ridge to our west.
The weekend looks quite pleasant with cooler and drier air filtering in behind the front.
Northwest flow aloft on the anticyclonic side of a upper ridge over the southwest CONUS will promote drier and more stable weather with cooler than normal temperatures into the weekend. Highs today will range from the low 60s to low 70s.
301 PM MDT Fri Jun 23 2017 Stratus stayed in over most of the plains today to produce a cooler than the already cool forecast we had. An upper ridge from Arizona over the west coast will continue northwesterly flow aloft across the area through Saturday. Some cloud cover will likely remain over the plains tonight, more than originally forecast, so have gone ahead and warmed the lows by a couple degrees. The upper ridge will build in slightly to allow for warmer temperatures tomorrow, readings in the low 70s are likely over the plains, and 60s to 70s over the high terrain.
249 PM EDT Fri Jun 23 2017 High pressure extending into the forecast area from the Atlantic today will weaken tonight ahead of an approaching cold front.
A pair of upper lows over southern Canada will continue to provide an cyclonic flow aloft across our forecast area through the weekend.
Best place to be is at the beach but with the high risk of dangerous rip currents it's not advised to get into the water so you should only look at the water Overnight will remain quite muggy and just plain gross. Coastal troughing/convergence will be better with a bit less of a capping inversion as the mid-level ridging and heat core move towards the west.
Strong surface ridging remains north of the CWA with ridge axis expected to slide south and east of the CWA overnight into Saturday. Models also show weak inverted trough building into the east side of the central Rockies late overnight into Saturday. While the region will see decreasing cloud cover overnight with the ridge cresting over the CWA. This coverage will increase from west to east during the afternoon hrs as ridge shifts more eastward allowing for trough/precip to move off eastern Rockies into the Plains. northerly flow going light with decreasing cloud cover will give the area overnight lows ranging from the upper 40s to the lower 50s.
A very strong (by June in the southern Plains standards) cold front extended approximately from KMKO to KSRE to KLAW to KLTS at 18Z. Despite the showers in northwest Oklahoma and the elevated showers in the southwest, the trend of the high-resolution models has been drier for this afternoon. The cold front has moved southeast of I-44, but temperatures continue to be a bit warmer than the hourly grids suggested. Cold front making its way into far northwest Oklahoma early this morning with a steady progression south and east through the day expected. Some acceleration possible late this morning and this afternoon as s/wv trough currently moving through Colorado progresses eastward. This trough will also allow scattered storms to develop near and north of the front.
339 PM CDT Fri Jun 23 2017 Cold front is about ready to push south of the area.
While Cindy is leaving, and widespread rain will end, a cold front will push into the region from the northwest by lunchtime.
Expect the mid-level ridging to provide good resistance to the first wave of instability unless a significant mcv were to take shape over the next 18 hours. Upper air analysis last evening showed a weak trough over Texas. There was a cold front moving into the northern Panhandle. High pressure centered over the Gulf will continue to dominate today with hot conditions. Tonight the cold front will approach our area and Saturday it will move in.
/Issued 511 AM CDT Fri Jun 23 2017/ Surface cold front will move across the fcst area this morning with north to northeast winds in the breezy to windy categories with higher gusts at times behind this boundary. Low level moisture will be slow to return until later this weekend due to the drier atmosphere behind the cold front.
Otherwise, thick CU blankets the entire Tri-State region underneath ridging aloft. Upper level ridging will build in from the east for today, providing partly cloudy skies by this afternoon with only isolated to scattered convection expected across the area (20-30% PoPs). High temperatures are expected to reach the lower 90s across most of the area, and with muggy dewpoints in the low to mid 70s still in place across the area, heat index values are expected to peak near 100 degrees this afternoon.
1120 AM MDT Fri Jun 23 2017 Updated aviation discussion Cooler conditions, relatively speaking, will move into the area today behind the cold front and trough that passed through the area yesterday.
Large upper ridge centered over southern NM continues to remain the dominant weather feature for our area. The ridge is expected to weaken some this weekend resulting in a slight cooling trend for our area.
Elsewhere, the hi-res models also show convection developing across north Texas early Saturday morning as a cold front moves southward. We should see enough convection to help usher the cold front southward during the morning hours on Saturday. The front will likely halt it's southward progress during the afternoon and should remain north of the Highway 90 corridor.
A cold front moving into southern IL and southeast MO has initiated a broken line of showers and thunderstorms. Quiet weather will begin this evening following the departure of the last of the cold frontal showers and isolated storms. Much cooler and drier air will continue through the weekend. Overnight lows will be in the 50s, and daytime highs will be in the lower 80s.
244 PM CDT Fri Jun 23 2017 Seasonally quite strong Canadian High Pressure bringing cooler temperatures on breezy NW winds under a variably cloudy sky. Temperatures are in the lower 80s SE to the lower 70s NW as cold air spills in. Area lows should be in the lower 50s northwest to the upper 50s southeast sections. Highs should be in the lower 70s north to the mid 70s central and south.
344 PM CDT Fri Jun 23 2017 Showers and thunderstorms this afternoon have continued to gradually shift to the east this afternoon with the low level convergence axis shifting off to the east. The high PWAT airmass in the wake of Cindy will aid in high rainfall rates, so some locations could get some hefty amounts and thus a small risk of exceeding flash flood thresholds.
Cooler and Drier Weather Storms were a bit robust earlier this afternoon with several reports of wind damage and localized heavy rainfall. area are in the lower to middle 50s and that drier air will be filtering in tonight. An upper level ridge over the southwestern U. and a trough over the Great Lakes Region will put the Missouri Ozarks region in a northwest flow this weekend.
Showers and thunderstorms ahead of an approaching cold front are beginning to push into this warm and juicy airmass. Can't rule out some isolated showers and thunderstorms on Saturday across North Mississippi as the higher dewpoints may linger across the region.
Strong high pressure aloft will return to the region late in the weekend.
/Tonight through Saturday/ Cooler air spilling southward into the region today marked the beginning of a stretch of below normal temperatures. This is a result of a large trough that has established itself over the eastern two-thirds of the conus.
Forecast confidence is high: Finally seeing a few showers upstream with the arrival a weak wave and a cooler airmass. Cooler temps are expected tomorrow, with highs in the upper 60s to near 70.
347 PM EDT Fri Jun 23 2017 Redevelopment of showers and a few thunderstorms will continue through late afternoon before cooler and less humid air arrives behind the cold front and brings an end to activity by early evening. A clearing trend with cooler and less humid air will follow the exit of early evening showers/storms through the overnight and Saturday morning. This will occur under cool temperatures aloft carried in by the upper level trough now over the Midwest which will bring 500 mb temperatures from around -9 C today to around -18 C Saturday afternoon and evening. Daytime heating that will lift high temps into the lower 70s will produce at least scattered convection over lower Michigan.
345 PM CDT Fri Jun 23 2017 (Today and Tonight) Another hot day across West Central Texas, with both the upper level ridge in place as well as the low level thermal ridge. Also, isolated storms have developed close to a cold front across the South Plains, just northwest of the Big Country. Going with the highest Pops across the Big Country(likely) and chance Pops further south. The cold front will move south across the area tonight, and be located just north of the I-10 corridor by Saturday morning. For Saturday, expect much cooler temperatures with highs mainly in the 80s.
556 PM CDT Fri Jun 23 2017 Breezy northeast winds will continue to subside as high pressure builds into the region. Below normal temperatures will linger into the weekend across the area with highs in the lower 80s and lows in the 50s/around 60.
It is in advance of a subtle short wave trough that isn't doing much early this morning, but should be influential with daytime heating to build clouds and a few showers as it passes over southern MN and western WI later this morning. IR satellite shows clear skies over much of the Upper Midwest at 3 AM, with lower cloud cover confined to North Dakota and portions of northern MN behind a surface cold front.
With onshore flow prevailing today afternoon temperatures may be tempered a bit from 24 hours, but with warm Gulf and Bays temperatures our dew point readings should be 4 to 7 degrees warmer than yesterday.
They have formed along a cold front, which is working its way southeast. Storms will continue to move southeast with the cold front and should be out of the area by late morning. This will bring cooler temperatures and drier air for the next several days. Both the highs and lows are below normal for this time of year. The broad upper level trough over the Great Lakes, which is influencing our weather this morning, will not move much over the next couple of days.
A cold front is forecast to cross Indiana today, causing widespread showers and thunderstorms. High pressure will move in from the northwest overnight.
Circulation/low pressure will move east of the area late this evening/early morning.
Moderate to heavy rain will accompany the low is it progresses across southern Kentucky, moving into eastern Kentucky by mid-evening. A cold front coming in from the northwest, accompanied by widely scattered convection, will enter the region this evening and gradually push the rain out. Lows in the 50s Saturday night will be about 10 degrees cooler than normal.
327 PM CDT Fri Jun 23 2017 A slow-moving large upper trough over the northern CONUS will make its way into the Great Lakes through the weekend. The surface cold front has steadily pushed southward to the Arkansas Ozarks, with high pressure projected to build into the central Plains over the weekend.
243 PM CDT Fri Jun 23 2017 Water Vapor/Regional Radar Mosaic imagery this afternoon featuring a mid-level trough and associated scattered shower activity swinging eastward through MN. Looking for this trough and showers to continue rotating east into our area later this afternoon into this evening. For the rest of tonight, plan on partly cloudy and cool conditions with lows dipping into the lower/middle 50s. A rather vigorous mid-level trough/strong 700-300mb pv-advection will drop through the area for Saturday, bringing with it widespread shower/scattered thunderstorms by afternoon lasting into the evening.
Meanwhile flow aloft is from the nw with model indications of a minor shrtwv trof. Convective concerns are mostly decreased Sat, except across the Lower Trans Pecos where best SB instability gathers. Mid level pattern will likely exhibit a little more ridging from Tue-Thur with possible presence of mid level theta-e ridge axis Thur, promoting an uptick in precip coverage? Broadening cyclonic mid level flow will attempt to suppress mid level ridge keeping temps in check late in the extended, at least compared to the past week.
258 PM CDT Fri Jun 23 2017 A cold front pushing just south of I-70 at mid afternoon will move through se IL next few hours. Much drier air ushering into central IL on breezy northerly winds, with dewpoints in the low to mid 50s from I-55 nw while muggy upper 60s to mid 70s southeast of a Rantoul to Taylorville line. A nice early summer day for central IL on Saturday with mostly sunny skies and breezy nw winds with cooler highs in the middle to upper 70s.
/ISSUED 251 PM CDT Fri Jun 23 2017/ A cold front that is unusually strong for late June is continuing to move south across southeast Oklahoma and north Texas this afternoon. As the pattern changes slowly through the week, the highest rain chances (though not particularly high) will shift to northern Oklahoma, and finally to eastern Oklahoma by Friday. Another cold front may bring more rain/storms for next Friday and the weekend.
For today, the cold front will surge across the region bringing showers and thunderstorms. This will keep Gulf moisture at bay, as temperatures stay cooler than normal for late June.
652 PM EDT Fri Jun 23 2017 Cooler and less humid air will settle across the region tonight.
Convection has developed along an advancing cold frontal boundary oriented east-west from the southern South Plains through the southern Rolling Plains. This cold front will bring a very welcome break to the oppressive heat we have experienced that past week or so. Surface ridging will build in overnight behind this front with decreasing winds by mid morning.
08Z surface analysis shows a cold front just south and east of the forecast area. For today, temperatures will be a bit cooler with highs in the 70s, but dewpoints will be noticeably drier in the wake of yesterday's widespread showers and storms. For now, lows in the lower to mid 50s seem reasonable.
239 PM MDT Fri Jun 23 2017 Broad upper trough remains across the central CONUS today with an upper level just north of North Dakota. Base of the upper trough/jet is pushing across East River into the upper Midwest.
1140 AM MDT Fri Jun 23 2017 Cold front with accompanying showers and thunderstorms was in nern CO as of 10z, and will drop south through the region this morning, bringing a period of at least light rain to most of the eastern mountains and plains through midday. Clouds will continue to thicken this morning over eastern mountain slopes and across the plains, with mostly cloudy skies lingering into the evening, leading to very cool max temps, and a few locations will end up nearly 30f cooler than Thu.
