The upper level high remains entrenched from the dessert southwest through the four corners region and across Kansas. These systems have not been strong enough or had enough of a cold advection component to drive cooler air into the local area, but it does appear that a strong system well to the north today will push a surface cold front into far northern Kansas by Monday afternoon.
Strong high pressure aloft will expand north and west from the southern Rockies through the first part of the week, bringing hot temperatures to the region.
314 PM EDT SUN JUN 19 2016 High pressure into Monday.
140 PM CDT SUN JUN 19 2016 Upper ridge centered along the NM/CO border this morning will slowly wobble north. By Monday the ridge axis will stretch from Southern CA across AZ. This will allow easterly flow to move under the ridge.
After today, will show a mainly dry and hot forecast for several days as upper ridge builds east into the Central and Southern Plains. Unlike yesterday's model runs, which kept a dominate ridge, todays model runs weaken or retrograde the ridge slightly by late week.
As diurnal heating begins to mix drier air into the lower levels of the atmosphere later today, skies to become partly cloudy. Otherwise, partly cloudy skies to prevail elsewhere across the region with temperatures forecast to climb into the lower 90s.
1114 AM PDT SUN JUN 19 2016 Expect drier and warmer weather today and Monday as a ridge of high pressure builds over the Inland Northwest. A series of weather disturbances will move through the region and dampen the ridge.
Aloft a strong 600 dm 500 mb high was near the AZ/NM border and ridging northeast across IL where 500 mb heights were above 594 dm. Mild lows in the lower 70s overnight which similar MET/MAV reflect.
337 PM EDT SUN JUN 19 2016 High pressure. however summertime northwesterly upper-level flow pattern and the presence of weak surface fronts and troughs in the region continues to support slight chance to chance POPs.
While the bulk of the upper level energy will be well north of the local area, the system will drag its associated cold front across the region tonight, eventually laying it up west to east across IA/IL as it departs into southeast Canada. Should see 90 or warmer for many locations. Thankfully, dewpoints (for the most part) are expected to hold in the low to mid 60s, helping keep heat indices relatively in check. Cooler (compared to the past few days), more seasonable/less humid air still on track for much of the new week post the cold front sinks south tonight. A cold front will move through the TAF sites between 20.
A weak upper level low just offshore will bring a chance of showers back into the area by Monday evening.
1124 AM MDT SUN JUN 19 2016 Windy conditions will continue for the next few hours across Dawes and Sioux counties with the low level jet overhead.
The low level winds will become very light on Monday and halt the advection of drier air.
Not a whole lot of synoptic forcing with ridging at surface and aloft.
241 PM EDT SUN JUN 19 2016 Dry high pressure will build into the region through Monday. This afternoon, Dry High pressure remains centered off to the north of the area, with ridging extending down into the CWA. This will keep winds out of the east, helping to keep afternoon temperatures cooler than normal. Tonight, With high pressure still over the area, skies become clear and winds light and variable/calm.
Still feel at least scattered convection will sustain itself however due to a noted cold front aloft and weaker mid level mechanical forcing. /Monday through Sunday/ A weak cold front will be dropping southward across Iowa on Monday morning and will reach central Missouri and northeastern Kansas by Monday night.
Temperatures will also be a few degrees cooler than what has been experienced recently, with lows tonight in the upper 60s and low 70s, and highs on Monday in the mid to upper 80s.
313 PM CDT SUN JUN 19 2016 An upper level area of high pressure is currently over the Plains extending into the area this afternoon. Highs this afternoon will range from the middle 80s to around the 90 degree mark with heat index values in the lower to middle 90s. Monday will almost be a repeat of today, with highs in the upper 80s to the lower 90s and index values in the lower to middle 90s. The upper level ridge will be to the west of the area on Monday setting up an upper level northwest flow pattern over the region.
Some high clouds are streaming in from the north around the eastern edge of the large ridge that is anchored in NM/CO.
311 PM EDT SUN JUN 19 2016 After one more warm day, a cold front should bring showers and thunderstorms on Monday night, as well as a return to near normal temperatures. While the main rainmaker during the near term forecast will come with the passage of a cold front Monday night, have added slight chance pops at all locations during the day on Monday.
A cold front will approach the area from the north late in the day Monday.
High pressure at the surface and aloft will continue over the region through Monday.
Sunny skies and warming temperatures will continue on Monday for the entire Northern Rockies under developing high pressure, with daytime highs expected to push well into the 80s for most valley locations Monday afternoon. Take proper measures to protect plants tonight, in case temps do hover close to the freezing mark Monday morning.
343 PM EDT SUN JUN 19 2016 Dry high pressure will build into the region through Monday. This afternoon, Dry High pressure remains centered off to the north of the area, with ridging extending down into the CWA. This will keep winds out of the east, helping to keep afternoon temperatures cooler than normal. Tonight, With high pressure still over the area, skies become clear and winds light and variable/calm.
Temperatures will climb a degree or two warmer than today.
330 PM MDT SUN JUN 19 2016 High pressure remained stretched across the Desert Southwest to the central High Plains today. This high based moisture appeared insufficient to fuel even isolated storms over the higher terrain late this afternoon and early evening. Another hot day in store Monday as high pressure persists over the region. Marginal flow beneath the ridge suggests light terrain driven winds. This high based moist convection will generate little measurable rainfall and strong outflow winds.
154 PM EDT SUN JUN 19 2016 High pressure is bringing warm and dry weather to the region this afternoon and tomorrow.
Upper level high pressure remains over the southern Rockies with a ridge axis extending into the Ohio Valley. high pressure centered over the Mid Atlantic States continues to dominate the weather pattern. Highs today will once again range from the upper 80s to lower 90s with heat index values generally in the low to mid 90s. The upper level ridge will continue to flatten as an upper level trough. As the trough pushes into eastern Canada. the upper level ridge will retrograde and amplify into the Rockies.
The large upper ridge continues to shift into the Plains while flattening out.
Meanwhile an upper level ridge north of the region extending eastward from the center of high pressure over the four corners area will very slowly drift southward through late Monday afternoon.
249 PM CDT SUN JUN 19 2016 A large ridge of high pressure across much of the southeast U. The short term models are generally agreeable in building the ridge of high pressure further southwest into the Tennessee valley region through Monday. The proximity of the upper ridge axis to the forecast area will result in a southwest low level flow setting up across the forecast area.
334 PM CDT SUN JUN 19 2016 At 20z a Surface cold front has nearly pushed through the FA and was stalled roughly along a Baudette-Bemidji-Breckenridge line. A more stable and dry airmass settles into the area overnight with dewpoints dropping into the lower 50s for most areas by around midnight.
202 PM EDT SUN JUN 19 2016 As the upper level ridge to our west retrogrades, a trough will eventually develop over the eastern United States.
345 PM MDT SUN JUN 19 2016 Satellite showing cold front entering portions of the northern counties of CO bringing cooler temperatures and increased moisture behind it. Look for a more mild evening with clouds moving in behind the front that will maintain overnight temperatures in the low 60s. Will increase pops for the higher elevations and onto the Palmer Divide for tomorrow afternoon.
Surface analysis and model data depict a weakening cold front boundary drifting south across the CWA, and probably moving south of the area during the overnight hours.
The upper ridge is now oriented sw-ne acrs the srn Rockies, curving east toward the TN valley.
342 PM CDT SUN JUN 19 2016 A cold front was moving slowly eastward into northeast SD/west central MN this afternoon. Otherwise, the models all show cooler and drier Canadian air building into the region tonight and Monday as high pressure ridging builds in. This will bring mostly sunny skies and below normal temperatures to the region on Monday with highs in the upper 70s to the lower 80s.
112 PM EDT SUN JUN 19 2016 High pressure will remain over the Carolinas through Monday. This high will weaken by midweek as a cold front approaches the Appalachians. The center of the high is forecast to shift a bit south and westward tonight. Thus, given this and air mass modification expect overnight lows will generally be a few degrees warmer than this mornings values. Expect lows to range from the lower 50s in the usual rural cold spots to around 60 in the urban areas.
Tonight THROUGH Monday High pressure will dominate the weather through Monday. A weak dry cold front moved south up to near the continental divide over night and will erode through monday with increasing southwest winds spreading up from the southwest through the day. Monday night THROUGH Sunday High pressure will dominate the weather with generally hot to very warm temperatures and dry conditions into mid week.
304 PM EDT SUN JUN 19 2016 High pressure will remain over the area through Monday.
403 PM MDT SUN JUN 19 2016 The cold front appears to have made it south through our eastern plains this afternoon based on the wind shift observed in sfc obs, although temps have yet to cool off much. The main concern for tonight will be stratus, fog and even drizzle development along and just to the east of the Laramie Range as winds will shift to the east- northeast behind this front, ushering in cooler and more moist air overnight. With a cool and more stable airmass in place tomorrow, could be difficult to see convection fire anywhere but the higher terrain along and west of the Laramie Range. However, some weak isentropic lift across the southern panhandle may provide support for showers and t-storms in the afternoon and evening, especially as the low level jet develops.
251 PM CDT SUN JUN 19 2016 A weak, inverted upper-level trough along the northern gulf coast producing scattered showers and thunderstorms across the ArkLaMiss southward toward an east/west elongated sea breeze boundary across southwest Louisiana and southeast Texas. Showers and thunderstorms to gradually diminish through the evening with temperatures overnight falling into the low to mid 70s.
Tonight and Monday The latest RAP analysis and satellite/radar imagery show a weak cold front stretching southwest across northern Minnesota to central South Dakota early this afternoon. Strong convection could be underway along a cold front moving east across Minnesota at the start of the evening. The cold front will exit the region by 15z, ending any precip threat over east-central and northeast WI. Monday Night Through Sunday Much of the period characterized by summer NW flow pattern as large upper ridge builds over southern/central Rockies.
200 PM PDT SUN JUN 19 2016 High pressure will remain over the desert southwest this week. Winds will return to more typical afternoon and evening breezes with temperatures rising into the 80s across the Sierra valleys and 90s in the lower elevations. Ridge over the desert southwest will remain flat due to a persistent trough over the northeast Pacific.
as region continues to lie under a broad upper level ridge. It will be this front/trough combo that will play into the region's weather tonight on into Monday. with the trough ahead of the front working further into the CWA before dissipating later tonight. The issue with any potential possible formation and its eventual push into the CWA is the dry dome of ridging already in place over the area. Overall strong ridging aloft will keep the region under a blanket of 90s once again.
with temperatures running a few degrees cooler (and Tds about 5-10F lower) than this time yesterday. Broad ridging conditions will continue to dominate the southern half of the country. with the ridge axis shifting a bit farther east toward mid-week.
Warm in the interior locations, with highs in the low 90s.
High pressure continues to build in from the E at the sfc and from the west aloft, keeping conditions dry today. With high pressure at the sfc and aloft, VFR conditions will prevail thru the period. /Issued 353 AM CDT SUN JUN 19 2016/ Alabama will remain on the eastern side of a large upper level ridge through much of the upcoming forecast period, which will keep conditions relatively dry and warm to hot.
There is some cumulus on satellite, but there really isn't any trigger with upper level ridging and warm mid level temps as well.
Upper level ridging is in place across the region this morning and will remain through Monday. At the surface, high pressure is centered along the Appalachians, which a weak inverted trough stretches from eastern into central KY. This trough will lift northward today. Most of the high resolution mesoscale guidance suggests that this will be the case this afternoon, mainly along and north of the Ohio River.
303 PM MDT SUN JUN 19 2016 Satellite showing cold front entering portions of the northern counties of CO bringing cooler temperatures and increased moisture behind it. Look for a more mild evening with clouds moving in behind the front that will maintain overnight temperatures in the low 60s. Will increase pops for the higher elevations and onto the Palmer Divide for tomorrow afternoon.
443 PM EDT SUN JUN 19 2016 High pressure continues to bring warm and dry weather to the region into Monday afternoon. Monday night a cold front will bring showers and thunderstorms.
A strong ridge of high pressure over the region will result in record heat today and Monday. Water vapor imagery and 19/12Z upper-air plots show the ridge currently centered near northern New Mexico and southern Colorado. Meanwhile, an inverted trough extends from northeast Mexico into southern Texas, with a disturbance also moving through the Texas panhandle and southeast New Mexico from northeast to southwest. Continue to expect record or near record high temps this afternoon and again on Monday as the high is expected to be in the same general location.
High pressure will build over the Four Corners region through midweek leading very hot conditions across the area.
High pressure from the Ohio Valley west into eastern Kansas will gradually move off to the east today. This will send the cold front further south tonight slowly into southern Nebraska late tonight. This will yield highs in the lower to middle 90s. Lows tonight will range from the upper 60s to the lower 70s. Rather fast upper flow over the northern states and upper high over the south remains to dominate the these periods. Slight warming ahead of the front Monday should bring a warmer day, with heat index values likely breaching 100.
420 PM CDT SUN JUN 19 2016 Very moist cyclonic low level flow near the Central Gulf Coast is supporting scattered shower/thunderstorm activity along the Highway 98 corridor in south central Mississippi extending into northeastern Louisiana. Going through the next couple of days, there will be a gradual decrease in diurnal thunderstorm coverage as the mid level ridge intensifies and increases subsidence and stability over the ArkLaMiss.
A much welcome cooler airmass returns on Monday, with highs only in the upper 70s and low 80s.
144 PM EDT SUN JUN 19 2016 An Upper level ridge will provide dry weather and warm temperatures today into Monday.
Storms should move east of our CWA by around midnight as the surface cold front continues to make steady progress to the southeast, but at least some severe/heavy rain threat is expected to persist well into the evening across northwest Wisconsin. Gusty west/northwest winds are expected area-wide on Monday as much drier and cooler air is advected into the region as the main upper level trof continues to deepen to our east. Cooler northwest flow will result in some lingering clouds on Monday night, but clouds should gradually clear from the southwest as the night wears on.
400 PM CDT SUN JUN 19 2016 Upper level ridging influences will provide for mostly clear to partly cloudy skies through Monday night. Surface riding pattern will be defined by high pressure influences across the central and southern Appalachian mountains.
421 PM EDT SUN JUN 19 2016 Low pressure off the Southeast US coast will move north Monday remaining well offshore. High pressure will remain over the region through Monday.
An inverted trough and unstable atmosphere has resulted in isolated convection across much of the CWA this afternoon.
Coupled with a weak inverted trough passing through from the northeast, this will continue to bring the threat for showers tonight, mainly along the coast, and tomorrow areawide.
358 PM EDT SUN JUN 19 2016 As the upper level ridge to our west retrogrades, a trough will eventually develop over the eastern United States.
with slightly cooler afternoon high temperatures expected.
Another nice day on Wed, but then a return to showery but mild weather as a new upper low arrives from the west.
/issued 352 AM CDT SUN JUN 19 2016/ Midsummer-like weather to prevail over the next several days, as the Midsouth remains under the eastern periphery of broad upper level height ridge centered over the southern Rockies.
/Issued 439 AM CDT SUN JUN 19 2016/ The latest tstm complex currently over swrn Ok and ern sections of the low rolling plains should pretty much miss our fcst area except for Collingsworth county, which is getting grazed by this complex with a few showers and tstms. Otherwise, generally dry weather is anticipated for the remainder of the TX and OK Panhandles today as an upper level ridge of high pressure over the central and srn plains and swrn states remains in control of our weather. This upper level ridge of high pressure is now progged to reorient itself wwd early this week.
MONDAY TEMPERATURES WILL BE 15-20 DEGREES COOLER THAN SUNDAY.
High pressure and dry southwest flow aloft will remain in place through Monday.
high pressure will continue to dominate our weather across the region for today. A disturbance passing across southern Canada will briefly flatten the upper level ridge across northern Colorado into Wyoming this afternoon. the system passing across southern Canada will continue east with the high pressure overhead rebuilding northward into Monday morning.
Cold front has made its way through the forecast area with pressure rises moving through the far south central and James River valley. A secondary trough with another area of pressure rises was moving through north central MT and southwest Saskatchewan. Clouds associated with the cold front have exited the area. Clouds associated with colder air behind secondary trough have not yet reached the northwest forecast area. Noticeably cooler and drier tonight. Seasonable temperatures are expected to start the work week with highs in the lower 70s in the Turtle Mountains, to maybe the lower 80s far southwest.
Coastal areas will see warmer temperatures too, but the coast is expected to remain relatively mild as light onshore flow predominates during the afternoon and evening hours. As expected the combination of a ridge of high pressure, very high sun angle, drier air, and a clear start to the day has helped to push temperatures up very warm levels and in most cases at least 5 degrees above Sunday. Warm weather can be expected for the remainder of the week as the ridge over the southern US keeps the storm track well to our north.
An upper level +PV anomaly lies just off the mid-Atlantic coastline with a broad upper level ridge to its west over the southwest and the southern plains, leaving mostly northerly flow aloft of the forecast area today. At the lower levels, a ridge of high pressure is centered along the mid-Atlantic states.
243 PM CDT SUN JUN 19 2016 Should continue with a generally rain-free forecast tonight/Monday as a large H50 ridge of high pressure remains draped west to east across the lower MO and Ohio Valley region. Changes begin to take place later Monday night through the rest of the short term as the mid level ridge shifts southward toward the northern Gulf coast states and the flow aloft becomes more northwesterly.
615 PM EDT SUN JUN 19 2016 After one more warm day, a cold front should bring showers and thunderstorms on Monday night, as well as a return to near normal temperatures. While the main rainmaker during the near term forecast will come with the passage of a cold front Monday night, have added slight chance pops at all locations during the day on Monday.
/issued 140 PM CDT SUN JUN 19 2016/ Upper ridge centered along the NM/CO border this morning will slowly wobble north. By Monday the ridge axis will stretch from Southern CA across AZ. This will allow easterly flow to move under the ridge.
226 PM PDT SUN JUN 19 2016 High pressures in place over NorCal will result in a warming trend with high temperatures nearing 100 degrees by middle of the week.
The center of upper level ridge remains well northwest of the region this afternoon. Cloud cover and the chances for rain should hold temperatures in the low to mid 90s tomorrow.
Despite lingering low level moisture, convergence along passing sfc cold front very weak. Otherwise, period of low clouds and possible patchy fog to accompany passing weak cold front early this morning. Drying continues into the low levels through the morning, overwhelming lingering low level moisture. Current cloud cover helping to keep temperatures mild early this morning, so returning sunshine will help daytime readings rebound into the low 80s most areas.
1224 AM CDT FRI AUG 5 2016 Main feature aloft this afternoon continues to be the low pressure system sliding east across southern Canada, now having moved into far western portions of Ontario. Generally zonal flow remains in place across the Central Plains, with the main impact from that system being the accompanying surface cold front sliding south today. The cold front currently moving through the CWA will continue sliding south tonight, with models in pretty good agreement showing it outside of the CWA by midnight and into southern KS by sunrise Friday. Aloft, high pressure remains in place over the Southern Plains, but it's a weakly amplified high, keeping flow across the Central Plains zonal. Winds across the area will be easterly, and with plenty of cloud cover expected, cooler temperatures are expected.
1232 AM CDT FRI AUG 5 2016 The cold front is pushing through northwest Wisconsin and should exit by midnight at the latest. Synoptically, a cold front will move through the CWA tonight. Still will see breezy winds on Friday out of the northwest due to the tightened pressure gradient behind the departing system and high pressure building in behind it.
259 AM CDT FRI AUG 5 2016 A cold front was bisecting the forecast area early this morning while widely scattered showers and isolated thunderstorms accompanied the front. Highs may struggle to climb out of the lower 80s across much of central KS while locations near the OK state line may climb into the upper 90s. The mid/upper ridge is progged to amplify across the southern and central plains states through the period.
The 500mb ridge across the south central United States this morning will continue to provide subsidence across much of the state today through Saturday.
