/issued 430 AM CDT FRI JUN 10 2016/ Water vapor imagery depicts the upper level ridge shifting over the mid-section of the country, remaining the primary influence on our weather. However, we are displaced south from the center of the ridge axis and a weak upper low over southeast Texas remains in place this morning. Temperatures will once again range from the lower to mid 90s with higher humidity values making it feel even hotter during peak hours of afternoon heating.
336 AM CDT FRI JUN 10 2016 An area of low pressure and cold front is tracking across the region this morning.
249 AM PDT FRI JUN 10 2016 A trough of low pressure moving into the Pacific Northwest will continue to bring cooler air to the lower elevations today.
403 AM CDT FRI JUN 10 2016 High pressure and dry air will continue to dominate the weather across Central Alabama today. A few more clouds are possible this afternoon than yesterday, but with increasing thicknesses, afternoon highs will be a few degrees warmer.
Mid-level ridging will also help inhibit the entrance of cold air that could help establish better lapse rates to support stronger convection. The high humidity could be uncomfortable to hazardous for those outdoors for extended periods of time in these areas that are expected to reach around 90 for maximum temperatures today just because of the moist airmass present over the region. Saturday isn't too disimilar from Friday with deep layer high pressure continuing over the region.
145 AM EDT FRI JUN 10 2016 Aviation It will be warmer and the weather will be more active this afternoon through Saturday.
Weak high pressure over the area today will move offshore tonight. A warm front will lift through the area Saturday.
Along coastal areas of Ne Fl and Se Ga drier and more stable air closer to the ridge axis will help suppress and push most convection to the northwest. A range in temps from the lower/mid 90s inland to the mid.
421 AM EDT FRI JUN 10 2016 Dry and warmer today. Shower and thunderstorm chances will increase Saturday as a cold front approaches and crosses the region Saturday night. Dry atmosphere remains in place through the day and the ridge to the west drifts eastward. The warm front finally gets a good eastward kick late tonight and into Saturday, as stronger low level flow develops and ridge shifts further east.
450 AM MDT FRI JUN 10 2016 An upper level ridge wl be ovr the forecast area today and tonight. High temps today wl be above average by around 10 degrees, with readings approaching 100 ovr the southeast plains and in the 80s ovr the high valley areas. A weak disturbance, ahead of the trough moving into California, moves into western Colorado, and a plume of middle and upper level moisture will move into Colorado from the south.
303 AM CDT FRI JUN 10 2016 Another warm, dry and sunny day on tap! With the mid level ridge strengthening itself over the SE today, highs will be able to top out a few deg warmer than yesterday, in the lower 90s for most locations. The warming trend continues tonight with lows warmer than previous nights, in the middle to upper 60s with an increase in mid level clouds from the SW later in the evening.
247 AM CDT FRI JUN 10 2016 High temperatures will remain a few degrees above normal for the next several days as ridge of high pressure aloft continues to dominate the overall weather pattern.
146 AM EDT FRI JUN 10 2016 Dry and warmer today. Shower and thunderstorm chances will increase Saturday as a cold front approaches and crosses the region Saturday night. Dry atmosphere remains in place through the day and the ridge to the west drifts eastward. The warm front finally gets a good eastward kick late tonight and into Saturday, as stronger low level flow develops and ridge shifts further east.
WITH LIGHT WINDS AS HIGH PRESSURE SITS OVER THE REGION.
/ISSUED / High temperatures will remain a few degrees above normal for the next several days as ridge of high pressure aloft continues to dominate the overall weather pattern.
5 inches, owing to dryness in the lower levels with surface dewpoints in the 50s and 60s. Aloft, weak troughing and some semblance of a left over shear axis will get trapped under the central CONUS ridge. By this time, the lower levels will established enough low level flow to bring in much higher moisture and solid sfc dewpts. Initially there will be a short wave ridge build and this will help to provide steeper lapse rates along with warmer sfc temps. The evolution of the upper pattern for late week is something that the global models are all indicating but is it sort of a strange setup for this time of year will a large sprawling ridge that builds from the Rockies and up into the Great Lakes. This looks to result in a couple potent disturbances dropping SW underneath the ridge.
327 AM CDT FRI JUN 10 2016 Upper level ridge is building over the region today. Since highs yesterday were up in the low 90s across most of the western 1/2 of the CWFA, and with warmer temperatures aloft over the area think we should easily get above the MAV and MET guidance so I bumped highs today a couple of degrees across the area. Carney Saturday still looks dry and hot as the upper ridge will build in over the area. Will keep going with highs in the lower to mid 90s which is above MOS guidance.
Upper trough remains anchored over the Pacific Northwest.
Both traditional MOS guidance and our local ensemble of convection allowing models places the highest PoPs in the eastern Big Bend region to the east of Tallahassee and near the Suwannee River. Highs today should be in the low to mid 90s, with higher values to the north.
Early morning temperatures were generally in the upper 50s to the lower 60s. As we head into tonight, the upper level ridge will keep skies mostly clear across the area.
348 AM CDT FRI JUN 10 2016 During the night an upper-deck cyclone was cut-off just off the WA Coast while a STRONG mid-upper deck high was centered primarily over AZ.
324 AM CDT FRI JUN 10 2016 324 AM CDT A warmer and drier day is expected today and the hot and humid conditions continue Saturday. A warm front lies just north of a Peru to Kankakee to Rensselaer line and it will continue north this morning. Expecting convection to form well northwest of the warning area closer to the forcing of the cold front over Minnesota. Dewpoints remain in the mid 60s overnight while lows drop into the low 70s leading to a sticky night. The heat continues Saturday with highs possibly even a degree or two warmer leading to heat indices around 100 degrees. Another round of storms form along the cold front in Wisconsin. Winds shift to northeast behind the cold front and cooler air moves in.
A weakness in the ridging aloft should allow the sea breeze to be active again today.
341 AM MDT FRI JUN 10 2016 Upper ridge will be over Colorado today. There is a bit of a moisture plume through the ridge axis which has been slow to wane overnight. This should help to feed some high-based convection on Friday afternoon and may keep the temperatures slightly cooler than they would be otherwise. By 12z Saturday the upper level ridge will have shifted east of the state increasing SSW flow. mainly over the higher terrain and Palmer Divide.
1234 AM CDT FRI JUN 10 2016 High pressure is still dominant. Tonight Through Friday night Upper level ridging is building overhead and will remain situated atop Arkansas through the short term period. Expect to see the CU a little further east tomorrow afternoon as high pressure continues to slide east of the state, and Gulf moisture makes headway into Arkansas.
430 AM CDT FRI JUN 10 2016 Water vapor imagery depicts the upper level ridge shifting over the mid-section of the country, remaining the primary influence on our weather. However, we are displaced south from the center of the ridge axis and a weak upper low over southeast Texas remains in place this morning. Temperatures will once again range from the lower to mid 90s with higher humidity values making it feel even hotter during peak hours of afternoon heating.
320 AM CDT FRI JUN 10 2016 Upper level ridge remains parked over much of the Central U.
1015 PM PDT THU JUN 9 2016 An upper level trough will bring a cooling trend through the end of the week.
Temperatures today look to be warmest through the Pecos and Rio Grande Valleys, where highs in the low 100s are possible again this afternoon, with 90s elsewhere.
This will result in the upper level ridge strengthening over the northern plains. Along with heat will be high humidity with dew points in the mid 60s to the lower 70s. With a weak boundary at the surface moving back and forth over the next few days along with a few weak upper level troughs moving through. The period opens with upper level ridging over the Plains.
However, compared to yesterday's soundings, the lower troposphere has warmed.
Upper ridge is centered over the CONUS, with a closed low over the Pacific Northwest. Chances increase this evening as weak wave/cold front being to push through the CWA. Flattened ridge sharpens on Friday behind this wave, and thermal ridge rebuilds. For Saturday, upper low and trough will move over southwest Canada / OR / WA. Southwest flow aloft over the CWA as upper ridge shifts into the Midwest. Lee trough in place across central MT into central WY.
122 AM EDT FRI JUN 10 2016 Dry and warmer today. Shower and thunderstorm chances will increase Saturday as a cold front approaches and crosses the region Saturday night. Dry atmosphere remains in place through the day and the ridge to the west drifts eastward. The warm front finally gets a good eastward kick late tonight and into Saturday, as stronger low level flow develops and ridge shifts further east.
623 AM EDT FRI JUN 10 2016 High pressure builds today and Saturday.
1135 PM MDT THU JUN 9 2016 Early afternoon WV satellite imagery and RAP analysis shows upper level ridging across the SW US. Due to the high bases, deep melting layer, and marginal CAPE values in our CWA, confidence in severe hail is lower. Friday: H5 ridge will be centered roughly across our western CWA, with large scale subsidence and an even drier air mass limiting any thunderstorm potential. Warmer guidance is even higher. With even minor bias corrections the mean/consensus guidance shows highs in the upper 90s, and it is certainly possible for some locations to reach the low 100s. Friday through Saturday remain hot and dry with the upper ridge moving into place over the central United States and southerly flow at the surface.
1037 PM PDT THU JUN 9 2016 Cooler, breezy and showery weather will impact the Inland Northwest today through the weekend. Satellite shows a wave coming around the closed low off the WA coast and diving south. with valley highs struggling to get out of the lower to mid 50s.
Upper trough slowly swings onshore over the Pac NW today. An accompanying cold front will push showers into western Baker and Harney county this morning, advancing to the OR/ID border by early afternoon. East of the border, the cold frontal passage will be marked by a sharp wind shift, but little chance for precipitation as the airmass is fairly dry. The upper trough continues eastward on Saturday with much of the region remaining dry. Temperatures are much cooler, with highs 5-10 degrees below normal.
An approaching upper-level trough along the West Coast will increase winds across Nevada today, with an increase in thunderstorm chances this weekend. A cooler airmass will also accompany this trough, dropping temperatures back to average or below average. In the meantime, expect windy and fairly warm conditions today due to an approaching upper level trof with associated cold front. Some increase in PWATs along the NV/ID border as moisture advects in from the northwest ahead of the cold front; however, not expecting more than some scattered cumulus in this area. This dry line actually slows the eastward progression of the cold front. High temperatures are likely to be lower on Saturday than compared to Friday, given the increase in cloud cover, or cooler airmass, which advects into Humboldt county.
333 AM PDT FRI JUN 10 2016 An upper level trough will bring continued cooler temperatures today and Saturday.
SHORT TERM (Today through Saturday): Broad 500 mb troffing will prevail over much of the South Central Plains states through Saturday.
326 AM EDT FRI JUN 10 2016 High pressure builds today and Saturday.
1204 AM CDT FRI JUN 10 2016 As advertised, the upper level ridge across the rockies has started to move across the plains, or closer to our area. Temperatures across the Lower Missouri River Valley have risen for the most part into the upper 80s to lower 90s this afternoon. The upper level ridge will continue to slowly push eastward through the weekend. At this point, it appears the highest heat indices will remain just under advisory criteria with some locations reaching 100F certainly not out of the question. Globals indicate the ridge will begin to breakdown by the end of this upcoming weekend.
149 AM EDT FRI JUN 10 2016 High pressure will move south and east of the area tonight which will allow temperatures to rise well above normal heading into the weekend.
For now have included PROB30 groups for HOB/INK/PEQ/FST where most model QPF aligns with trof axis and mid level mstr. /issued 235 PM CDT THU JUN 9 2016/ West TX and SE NM remains on the eastern periphery of a high amplitude ridge today that extends from the Desert Southwest NE through the Central US. At the surface, lee trough and a weak dryline extends south through eastern NM resulting in breezy SE winds across much of the region and dewpoints in the 50s most locations. The upper ridge axis will begin to shift east Friday however thunderstorm chances continue as weak disturbances traverse the region through the weekend.
Will however introduce a mention of MVFR CIGs at KBBD, KSOA, and KJCT after 09Z Tuesday morning, as moisture is expected to increase in the low levels. /issued 420 AM CDT MON OCT 3 2016/ (Today and Tonight) The area remains under upper level ridging early this morning, but that will change over the next 24 hours. A large and powerful trough currently moving through the Great Basin will move into the northern Rockies by tonight, increasing southwest flow and lift aloft in our area. Ahead of the trough during the day, low level southerly flow will increase, becoming somewhat gusty and increasing moisture across the area. This will likely result in isolated to scattered thunderstorms developing tonight to our west and northwest over the higher terrain.
457 AM MST MON OCT 3 2016 Cooler and drier air behind an exiting low pressure system north of Arizona has settled into the Desert Southwest.
Update: Tweaked pops for this mornings update to account for the current precipitation picture including the dry slot over the lower Yellowstone valley and Wibaux county. Gilchrist Previous discussion: With the large and active low pressure system now pushing through the central and northern Rockies, widespread moderate to heavy rain showers are expected to continue over the next few days. Meanwhile, warmer temperatures an a more unstable atmosphere over our eastern zones could lead to marginally severe thunderstorms there this afternoon and evening with small hail and gusty winds being the main threats.
725 AM EDT Mon Oct 3 2016 Weak low pressure will dissipate today as it moves into New England.
1037 AM CDT MON OCT 3 2016 Morning water vapor imagery shows upper trough digging west of us across the Great Basin. Lee trough over eastern NM will intensify this afternoon. while upper ridge builds across the plains and southerly winds increase.
610 AM CDT Mon Oct 3 2016 A partly to mostly sunny and breezy to windy day still looks good for today, as a strong upper low and cold front approach from the Rockies. For tonight the continued approach and arrival of the cold front, and upper impulses southeast of the upper low, should make for decent overall coverage of showers and storms spreading fairly quickly across the area from the west. Dynamics are not as strong as they will be further west, closer to the northeastward swinging upper low. Still feel the severe weather risk is on the low end for this event.
1257 PM EDT Mon Oct 3 2016 High pressure will build over the eastern United States through tonight. Tonight: As the high over New England begins to shift east, the weak offshore coastal trough will drift toward the coast.
730 AM EDT MON OCT 3 2016 High pressure will build southeast into the region and persist through mid-week. A deep upper level low over southern New England this morning will continue to slowly fill and open up through tonight as it drifts east-se. This action will allow an area of high pressure over the central Appalachians to strengthen and build southward along the spine of the Appalachians. The resultant nly low level flow will advect a drier and slightly cooler air mass into our region, with the better advection occurring tonight.
With an increase in cloud cover and cooler air advecting into the region from the north, temperatures will also be slightly cooler region-wide this afternoon. High pressure will then build over the eastern Pacific by midweek and build toward the coast late this week and into the upcoming weekend. SFO Bridge Approach. Rain showers will be possible today along with cooler than average temperatures as another mid/upper level system impacts the region. High pressure will then build over the eastern Pacific by midweek and toward the coast late in the week.
1031 AM EDT Mon Oct 3 2016 Weak low pressure will dissipate today as it moves into New England.
919 AM MDT Mon Oct 3 2016 The upper level low pressure trof will continue to move towards the forecast zones and widespread precipitation will continue.
737 AM EDT Mon Oct 3 2016 High pressure will build over the eastern United States through tonight. High pressure to the north of the area will expand east today, allowing a slightly more onshore flow to develop along coastal areas. The combination of the higher dewpoints across coastal GA and a weak coastal trough may allow for isolated showers or tstms later this afternoon. Tonight, as the high over New England begins to shift east, the weak offshore coastal trough will drift toward the coast. High pressure will remain north of the area while tropical cyclone Matthew moves north from near Cuba to the Bahamas.
1007 AM EDT Mon Oct 3 2016 High pressure will build over the eastern United States through tonight. Tonight: As the high over New England begins to shift east, the weak offshore coastal trough will drift toward the coast.
Deep layer cyclonic flow persists over the area this morning as the closed low, now centered over western Upstate New York, only slowly migrates east. A few showers have been noted on radar within a corridor of weak troughing in the Thumb. Forecast soundings maintain ample moisture in the lowest 5kft capable of supporting clouds through most or all of the day. With the thermal trough lingering over the area, highs will likely reach the mid 60s at best. Heights will steadily rise this afternoon through Tuesday as North Pacific energy continues to pour into the evolving longwave trough over the western United States, culminating in a closed low that will lift into Manitoba midweek. In the meantime, the ridge over Lower MI will undergo any appreciable amplification until Tuesday.
Winds will become sustained around 30 mph with the higher gusts approaching 45 mph by this afternoon. The steadier precipitation will focus over the west- central Idaho and eastern Boise mountains, tracking from northeast to southwest as it circulates around the low. To the west scattered showers this morning will dissipate as the low shifts further eastward during the day. Upper low in se Oregon will track ese along the northern Nevada border today and tonight. Next fast-approaching short wave trough in the eastern Pacific will spread light rain into eastern Oregon late tonight and Idaho Tuesday.
Lows in some areas of northeast California and far western Nevada dipped below freezing. /Issued 316 AM PDT Mon Oct 3 2016/ Cold northwest flow will prevail as low pressure exits into the Rockies.
The upper low which was located across KY over the weekend continues to drift slowly eastward across the eastern Great Lakes region this morning, with a trailing trough axis pushing through the lower MS valley. Short range model guidance is in agreement that another weak mid- level vorticity maxima will track across the TN valley today, before the longwave trough axis clears the region to the east this evening.
1224 PM EDT Mon Oct 3 2016 Dry and partly sunny conditions are expected today as high pressure builds into the region. Highs will be around 70 degrees with lows tonight in the low to mid 50s.
949 AM EDT MON OCT 3 2016 Combination of old frontal boundary and upper trough just west of the area are contributing to scattered showers and thunderstorms along the NE Florida coast this morning. However, with the trough in place and a moist and unstable atmosphere, expect additional showers and thunderstorms to develop by afternoon. Northeast winds will increase a bit during the afternoon as high pressure builds towards the Carolinas.
A cold upper low will cross northern Utah and southwest Wyoming today.
best chc of pcpn would appear to be through 21z in the high country. Temperatures are expected to climb into the lower 80s with relative humidities dropping to the lower teens. Satellite imagery shows an area of thunderstorms over the northwest corner of the state being driven by the upper level jet associated with the approaching upper trough that will bring the unsettled weather through this week. By Wed night into Thu there is still disagreement between the ECMWF and GFS with respect to an upper level trough moving across the rgn. By Sat and Sun a flat upper level ridge will be over the area with dry wly flow aloft. Thus it should by dry both days with warmer temps as readings rise back into the 70s across nern CO.

Southerly flow will return midweek with an approaching cold front drawing Gulf moisture N Sct convection mid to late week w/ fropa. with the upper ridging noted from the Srn Plains NNE across the Plains/Midwest and into Ontario expected to shift E to the MS Valley and Ern Great Lakes region. This will occur out ahead of the deep upper trough over the Great Basin. Sfc ridging will also persist across the region NE into the Great Lakes region for one more day as well.
828 AM EDT Mon Oct 3 2016 High pressure will build into the region bringing dry and warm weather for the week.
Bulk of the precip should dissipate a few hrs aft sunset, but will keep small PoPs in areawide overnight due to the high degree of instability coupled with increasing onshore moist flow.
942 AM EDT MON OCT 3 2016 A ridge of high pressure over the upper lakes will slowly shift east across the area tonight and tuesday then into new england for the rest of the work week.
1039 AM CDT Mon Oct 3 2016 Upper-level ridge across the region maintaining mostly sunny skies areawide.
1045 AM CDT MON OCT 3 2016 Combo of ridging aloft and a drier airmass has led to a clear and rain-free morning across the forecast area. and expect all convection to remain over the Gulf in proximity to lingering sfc trof. Satellite/surface obs showing clear skies this morning in the wake of mid/upper level trof advancing east of the region. Early morning clouds yesterday with aforementioned trof kept morning lows several degrees above that of this morning under clear skies. Anticipating a dry and pleasant day as dewpoints continue to remain on the low side. Afternoon highs will continue above the norm but overnight lows will be significantly warmer.
