330 AM CDT TUE JUN 7 2016 The short term starts off with high pressure over the area and cool temps this morning, with even some 30s across parts of northern Minnesota. The high drifts eastward today, but will provide fair skies and light winds. Meanwhile, an upper level ridge continues to drift eastward from the western states. With the high pressure drifting east across northern MN tonight, Beltrami and Lake of the Woods counties could get cool once again (almost to frost temps).
A cold front across the western Midlands will also move through the area early this morning and offshore by midday. Drier air will move into the forecast area this evening with high pressure and dry weather expected through the weekend. Cold front currently moving through the western Midlands will quickly cross the forecast area this morning and offshore around midday as TS Colin accelerates and moves along the NC coast. Clouds will also begin clearing as the cold front moves through the area with skies becoming mostly sunny by midday. With the cold front moving further offshore this evening drier air will overtake the region. Temperatures this afternoon will be in the upper 80s to around 90 with overnight lows in the lower to middle 60s.
330 AM CDT TUE JUN 7 2016 08z/3am surface analysis shows cold front settling south of the Ohio River, while 1017mb high builds into the Northern Plains. Northwesterly winds around the high will bring a cooler/drier airmass into central Illinois today. High temperatures will be considerably cooler than yesterday, only reaching the middle 70s. Big pattern change is still slated for the end of the week, as persistent upper trough over eastern Canada lifts northeastward and is replaced by a pronounced upper ridge.
Broken cloud decks above 5000 feet and northeast winds below 10 knots are expected during late morning and afternoon at the I-35 TAF sites as the weak upper low off the Texas Gulf Coast slides back to the W-SW.
106 AM EDT TUE JUN 7 2016 Low pressure will remain stalled to our northwest through Wednesday.
Overall, fog not expected to be as dense early this morning due to the further drying of the lowest levels. Still expecting gusty west- to-northwest winds this afternoon as pressure gradient tightens with incoming trough.
354 AM EDT TUE JUN 7 2016 Cooler weather is expected today into Wednesday as an upper level trough moves through. Clearing is expected tonight into Wednesday as high pressure builds in.
1135 PM MDT MON JUN 6 2016 Warm and mostly dry conditions will continue through the short term period as an upper level ridge remains anchored over the western CONUS. A weak backdoor front associated with this feature is helping to keep high temperatures down in the low 70s to low 80s for most areas today. Tuesday will continue mostly dry and warmer as ridge moves further east. with slightly cooler temperatures further east towards central South Dakota as surface front retreats to the east. Dew points should approach at least the low-50s which will help destabilize the area with day time heating.
Cold front moves through during the night and will be south and west of the area by the beginning of the day. High temperatures will be a little cooler due to the easterly upslope flow.
Lows Wednesday morning several degrees above normal, courtesy of convective cloud debris and S/SE flow, in the lower 60s. With the polar jet stream shifting way up north into Canada, the lower-mid troposphere will warm up substantially front he Intermountain West/Great Basin region all the way east to the High Plains, including southwest Kansas.
320 AM CDT TUE JUN 7 2016 Will be a very pleasant day today with high pressure in control. Tonight, the high pressure system will move off to the east bringing our low level winds around to the southeast. Southerly flow increases across the region on Wednesday as surface ridging slides off to the east. This will result in a warmer day with highs generally lower to mid 80s. It will also be a milder night with lows in the lower 60s.
315 AM PDT TUE JUN 7 2016 Dry conditions and above average temperatures will continue through midweek followed by cooler temperatures by the weekend.
1228 AM CDT TUE JUN 7 2016 Weak convection has formed over portions of northeast Kansas along a cold front. Additional activity may develop along or just behind the cold front as it pushes south. A quiet period of weather will follow into the weekend as a large upper ridge gradually builds into the Plains. The coolest day of the week is expected on Tuesday as weak cold air advection moves in behind the cold front.
With high dewpoints in the lower 70s still prevalent across the area early this morning, and temperatures within a degree or two of the dewpoint, we expect steady temperatures in the low 70s through daybreak. This should be followed by a very warm day with highs in the lower 90s.
Since then, lightning has picked up and velocities off TSDF and TLVX still show 30-35 kts at the lowest slice. Upper trough, which should bring us a few showers/storms late this afternoon, will swing through the region tonight. In its wake, we'll see a reinforcing shot of cooler and drier air. 6" and dewpoints in the low/mid 50s, will keep the forecast dry for now. For the overnight, high pressure will nose in from the west and we should see those clouds start to scatter out.
344 AM CDT TUE JUN 7 2016 Evening/overnight convection across the high plains will continue moving southeast across the Texas Panhandle early this morning. This activity will weaken as it moves into drier and more subsident air which currently resides across the Low Rolling Plains.
219 AM PDT TUE JUN 7 2016 A ridge of high pressure will keep the weather pattern dry for the next several days.
For 12Z aviation discussion below There isn't much to talk about during the short term forecast period, as high pressure settles in and fosters dry weather with mostly clear skies and relatively light winds. Lows tonight will dip into the lower 40s to lower 50s, with patchy fog possible in east central MN and west central WI.
A very weak secondary cold front will move through later this morning and exit sometime early afternoon. Upper trough axis rotates through this afternoon and pressure gradient tightens through the day. Most locations will see lows that range from the lower 50s to upper 50s.
118 AM EDT TUE JUN 7 2016 Cooler weather is forecast through the middle of the week before we warm back above normal by week's end. Otherwise, the cooler temperatures will be the most noticeable feature through the morning.
An early morning surface analysis showed a cold front dropping south out of southern Indiana into northern Kentucky. Otherwise, behind the front, dewpoints have dropped into the 50s along with readings in the low to mid 60s.
330 AM CDT TUE JUN 7 2016 A cold front will continue to pass through the area early this morning.
333 AM CDT TUE JUN 7 2016 There isn't much to talk about during the short term forecast period, as high pressure settles in and fosters dry weather with mostly clear skies and relatively light winds. Lows tonight will dip into the lower 40s to lower 50s, with patchy fog possible in east central MN and west central WI.
High pressure will build in from the west this afternoon and persist through late in the week. Colin is certainly looking more baroclinic in nature this morning with the core of the highest winds confined to the eastern half of the system. The dry air will essentially cap the atmosphere per area forecast soundings, despite highs warming into the lower 90s. There are signs that some mid- level clouds could work into western areas later this afternoon out ahead of an approaching cold front, but their impacts will be negligible. Tonight: A weak cold front will push offshore after midnight. Lows will range from the mid 60s well inland to the lower 70s at the beaches.
Another cold front will move southeast from the Great Lakes on Tuesday bringing another round of unsettled conditions for Tuesday into Wednesday. along with cooler temperatures.
Scattered showers/thunderstorms are expected to form by midday across southwest NY/northwest PA and continue to develop while expanding in coverage to the southeast across the central ridges and into the Susquehanna Valley by the afternoon.
Latest satellite imagery showed a mid to upper level trough extending from a closed low over Southeast Canada down to the Lower Mississippi Valley. On Wednesday mid to upper ridging will build across the region from the Plains. Nightly lows will range from the lower to middle 60s. This was especially the case for Wednesday night with the high clouds around.
While most of the state should remain dry as the main mid level trough stays to the east, the embedded pv anomalies wrapped around this low will brush eastern Wisconsin this afternoon and this evening, bringing the chance for light rain showers to the eastern cwa. Lows tonight are expected to drop into the middle to upper 30s across north central Wisconsin, with lows in the lower to middle 40s elsewhere.
An upper level trough reaches the Utah- Colorado border on Tuesday afternoon bringing some cloud cover to the region. Fairly dry air in this sector of the passing trough will keep conditions eventful except for a few shallow isolated showers or thunderstorms over the higher terrain. Specific humidity increases to 4 g/kg from the northwest on Wednesday as troughing remains over the area.
353 AM CDT TUE JUN 7 2016 Upper ridge centered west of Baja this morning with ridge axis running up through Idaho. The ridge axis will shift east as high pressure builds in from the west. There has been some storms overnight from the Panhandle back across the higher elevations of NM. By the weekend storm chances increase but mainly over the higher elevations out west.
334 AM CDT TUE JUN 7 2016 Upper level ridging will slowly build across the region through the short term portion of the forecast. This ridge will bring much above normal temperatures with each day progressively warmer.
355 AM PDT TUE JUN 7 2016 High pressure will build in by midweek with peak temperatures on Wednesday and a persistent coastal marine layer.
350 AM EDT TUE JUN 7 2016 A cold front will move south of the area this morning.
The mid and upper level trough off the Texas coast will close off again over Deep South Texas and northern Mexico today into Wednesday. As a result, the low and mid level flow across the southern CWA veers more easterly and the pool of moisture across the Coastal Plains is advected farther west through southern areas Today and Wednesday.
High temperatures will range from the low 80s in the Hill City, Norton and McCook areas to the mid 80s to around 90 from Burlington to Leoti. This is fairly close to the warmer mav guidance.
The ridge of high pressure continue to cause extremely hot temperatures lingering over the Northern Rockies today.
621 AM EDT TUE JUN 7 2016 A cold front will move across the region today producing showers and thunderstorms, with a few possibly being severe. An upper level low will move overhead on Wednesday and allow for another chance of showers and thunderstorms.
SFC/850 ridge axis shifts closer to srn WI. So temps should get back into the 70s though onshore flow will likely keep some cooler 60s near Lake Michigan.
A large area of hot high pressure has formed over the western half of the CONUS with a ridge stretching into British COlumbia and Alberta. Northeast Montana begins setting on the eastern side of this ridge under northwestern flow aloft. Farther west a large trough resides over the Gulf of Alaska. northeast Montana lies on the stable side of the ridge with a warming trend and dry conditions continuing. A vort max disturbance is expected to ride this boundary around the ridge and could easily generate a a few isolated to scattered showers and thunderstorms overnight that would likely die out Wednesday morning. ridge axis will migrate over the central montana mo0untains allowing some showers to for over them during the afternoon and evening hours.
A quiet afternoon will give way to overnight showers as the upper trough and another wave of energy rotates through the Great Lakes. Guidance keeps coming in progressively cooler, with maximums now progged between the upper 50s and lower 60s.
Dry high pressure will then build in from the northwest and linger through the remainder of the week. Cannot rule out a stray shower E of the Blue Ridge where low level convergence is maximized downwind of the higher peaks. High pressure will continue to build in tonight with mostly clear sky and low temps a few degrees below normal. As of 255 AM Tuesday: on Wednesday, the region will remain under dry NW flow as the H5 trough axis swings over the Atlantic coast. At the sfc, high pressure will build across the southern Appalachians from the Mid West.
603 AM EDT TUE JUN 7 2016 A cold front will move through today. Center of high pressure crosses Wednesday night.
An upper low, which has enhanced convective activity the past couple of days, will make it's way to the ID/WY border by this afternoon. Without the dynamic support of the exiting low, conditions remain too stable to support shower or thunderstorm development in the lower Snake Plain. With less cloud cover will see high temperatures several degrees warmer than today, possibly breaking some records for the date.
Have trended slightly warmer for today based on upstream temps yesterday as well as the cool performance of MOS yesterday.
To our north, another cold front was approaching the region.
313 AM EDT TUE JUN 7 2016 A cold front will move through today. Center of high pressure crosses Wednesday night.
329 AM CDT TUE JUN 7 2016 High pressure has resulted in clear skies throughout the Mid- South tonight. Temperatures today will be 1-2 degrees cooler than yesterday as the weak front pulls slightly cooler air into the region. A light jacket may even be utilized in locations near the Tennessee River where temperatures may fall to the low to mid 50s Tuesday and Wednesday night. A steep, stagnant upper level ridge will become centered over the Central U.
346 AM EDT TUE JUN 7 2016 Low pressure will remain stalled to our northwest through Wednesday.
140 AM EDT TUE JUN 7 2016 A cold front will cross the region this evening. Secondary troughs will follow for early Tuesday and Wednesday mornings.
311 AM PDT TUE JUN 7 2016 Cooling through the end of the week as high pressure weakens. The strong upper ridge covering the West will only shift a little further to the east today.
305 AM EDT TUE JUN 7 2016 Cooler weather is forecast through the middle of the week before we warm back above normal by week's end. Fries Upper-level trough axis will shift quickly to our east Wednesday leading to a drying and clearing trend through the afternoon. Deep mixing Wednesday morning means gusty winds will be common as the trough passes, but these should lessen by afternoon as the pressure gradient loosens.
Issued by the National Weather Topeka KS 150 AM CDT TUE JUN 7 2016 Northwesterly flow aloft will allow a weak cold front to sink southward to near Interstate 70 toward early this evening, with the front then moving slowly southward through South-Central/Southeast KS overnight. Weak high pressure will build into the missouri valley Tuesday, allowing for light winds, slightly cooler temperatures and mostly sunny skies. Will maintain low chances (20-30%) of thunderstorms Tuesday night into early Wednesday morning in central Kansas, as diurnally- initiated convection over the higher terrain of colorado/wyoming translates slowly eastward.
640 AM EDT TUE JUN 7 2016 High pressure will move from the northern plains this morning to the midwest tonight in the wake of a departing cold front.
ISSUED BY NATIONAL WEATHER SERVICE TOPEKA KS 335 AM CDT TUE JUN 7 2016 A LONGER WAVE LENGTH UPPER TROUGH ACROSS THE EASTERN US WILL SLOWLY TRANSLATE EAST OFF THE ATLANTIC COAST WHILE AN UPPER LEVEL RIDGE ACROSS THE WESTERN US MOVES EAST ACROSS INTO THE PLAINS. ENJOY THE SLIGHTLY COOLER TEMPERATURES TODAY WITH HIGHS IN THE MID 80S ACROSS THE WESTERN CWA AND LOWER 80S ACROSS THE EASTERN HALF THE CWA.
312 AM EDT TUE JUN 7 2016 A cold front will move across the region today producing showers and thunderstorms, with a few possibly being severe. An upper level low will move overhead on Wednesday and allow for another chance of showers and thunderstorms.
330 AM CDT TUE JUN 7 2016 (Today and Tonight) The gradual warming trend under upper level ridging will continue today and tonight.
346 AM CDT TUE JUN 7 2016 High pressure was building into the region from the Northern Plains. to the lower/middle 50s elsewhere. High pressure will slide across the region today, providing mostly sunny skies. Otherwise, plan on cooler than normal highs in the 60s. High pressure directly overhead tonight with nearly calm winds and mostly clear skies expected. This will lead to respectable amount of radiational cooling which will lead to chilly overnight lows in the lower 40s across central WI and middle/upper 40s elsewhere. High pressure will begin sliding off to the east on Wednesday for onset of warm air advection. Under mostly sunny skies, look for highs in the upper 60s northeast of I-94, and in the lower/middle 70s elsewhere.
High pressure aloft will bring one last warm day today. An upper trough will affect the area Wednesday into the weekend for cooler weather with a chance of showers. An upper ridge over the area will shift a bit inland today with gradually increasing low level onshore flow. Low level onshore flow will increase tonight and Wednesday as an upper trough moves over the Pacific Northwest. The upper trough will also bring a small chance of showers later Wednesday, mainly over the mountains.
238 AM CDT TUE JUN 7 2016 A more pronounced dry cold front extends from near Dayton, Ohio southwest into northwestern Kentucky and southern Missouri at this time. A few showers and storms keep developing just south of the front along a weak pre-frontal trough axis extending from the front into southwestern Kentucky. Mesoscale models weaken this pre-frontal trough axis towards daybreak as the front pushes southeast into Southern Middle Tennessee. Highs in the lower to mid 80s look pretty good. Based on upstream dewpoints near and just behind the front low temperatures in the lower to mid 50s is reasonable.
UPPER AIR PATTERN IS CHARACTERIZED BY A SLOW MOVING UPPER LOW ACROSS THE CENTRAL ROCKIES WITH A WEAKENING RIDGE TO THE EAST OF THIS FEATURE. THE RIDGE WILL BEGIN TO MOVE EASTWARD AND THE UPPER LOW WILL DO THE SAME AND WEAKEN AS IT MAKES IT ACROSS THE CENTRAL PLAINS. THE SURFACE PATTERN WILL BE CHARACTERIZED BY MAINLY EAST TO SOUTHEAST WINDS AND A WEAK INVERTED TROUGH ACROSS SOUTH TEXAS. THERE IS SOME DISCREPANCIES BETWEEN THE MODELS ON LOCATIONS OF PRECIPITATION SO CONFIDENCE IS ON THE LOW SIDE TODAY CONCERNING PRECIPITATION.
1048 AM MDT TUE APR 19 2016 THE FORECAST AREA REMAINED UNDER THE INFLUENCE OF THE BROAD CLOSED LOW WHICH HAS DOGGED THE REGION OVER THE PAST SEVERAL DAYS. THE LOW CENTER WAS JUST SHIFTING EAST OF COLORADO/S CENTRAL DIVIDE MOUNTAINS EARLY THIS MORNING. THIS ISN/T THE END OF THE STORY FOR THE PERSISTENT LOW PRESSURE SYSTEM AS A 70 KT JET WORKING SOUTHWESTWARD ON THE WESTERN FLANK OF THE SYSTEM GUIDES ANOTHER VORT LOBE ACROSS NORTHEAST UTAH AND NORTHWEST COLORADO TODAY AND TONIGHT. PARTLY CLOUDY AND DRY CONDITIONS ARE IN STORE FOR SOUTHEAST UTAH AND THE LOWER ELEVATIONS OF SOUTHWEST COLORADO.
WV LOOP CONTINUES TO SHOW THE MAIN UPPER LOW ROTATING OVER THE CENTRAL ROCKIES.
THE LARGE UPPER LEVEL LOW STILL REMAINS NEARLY STATIONARY TO OUR NORTHWEST AND WE WILL CONTINUE TO BE UNDER THE INFLUENCE OF IT FOR THE NEXT FEW DAYS WITH CONTINUED RAIN CHANCES. SYNOPTIC SCALE MODELS ARE SHOWING ANOTHER IMPULSE OF ENERGY ROTATING AROUND THE SOUTHERN PERIPHERY OF THE UPPER LOW. SOME OF THE HIGH-RES MODEL GUIDANCE IS SHOWING THIS ACTIVITY EVENTUALLY CONGEALING INTO SOME SORT OF ORGANIZED COMPLEX MOVING INTO THE CWA TONIGHT.
STRONG RIDGE OF HIGH PRESSURE WILL REMAIN OVER THE REGION WITH NEAR RECORD HIGH TEMPERATURES TODAY AND SUNNY SKIES. A LOW PRESSURE SYSTEM OFF THE COAST OF CALIFORNIA WILL BEGIN TO SPREAD SOME CLOUDS INTO CENTRAL OREGON OVERNIGHT. THIS LOW WILL WEAKEN AND TURN INTO AN OPEN WAVE AND LIFT ACROSS THE REGION ON WEDNESDAY.
Some evidence in model data that shrtwv trof/outflow boundary will sustain convection into Tue night/Wed AM, possibly in the ern CWFA? Cyclonic flow persist into Wed PM with the development of a good example of the old school "Marfa Front" in model data. Meanwhile with aforementioned cyclonic flow a strong shrtwv trof will drop sewd thru the Panhandle early Thur AM and is likely push a cluster of storms which could impact the N-E CWFA. Mid level ridging Fri to favor a warm-up, but drier. There will be the chance for a well defined shrtwv trof to move into the Trans Pecos Sat PM, GFS is quicker than ECMWF and as such farther NE with precip.
OTHERWISE DRY CONDITIONS WILL CONTINUE TO PREVAIL ACROSS THE MID STATE PER HIGH PRESSURE INFLUENCES SFC/ALOFT CONTINUING THEIR HOLD ON THE MID STATES WX PATTERN. EXPECTING THOUGH HIGH LEVEL CLOUDINESS TO CONTINUE STREAMING ON TOP OF UPPER LEVEL RIDGING INFLUENCES AND THUS CONTINUING TO MOVING ACROSS THE MID STATE W TO E TODAY THRU TONIGHT. STILL EXPECTING A CLOSED LOW TO MOVE INTO NRN PORTIONS OF THE MID MS RIVER VALLEY BY THU AFTERNOON. AND TIMING OF ALL OF THIS ASSOCIATED WITH A SFC FRONTAL PASSAGE WITH A MORE PRONOUNCED BROAD UPPER LEVEL TROUGHING PATTERN APPROACHING THE MID STATE LATE THU NIGHT. MAINLY IN THE LOWER 80S.
1002 AM EDT TUE APR 19 2016 A WEAK COLD FRONT WILL PUSH SOUTH INTO THE AREA THROUGH TODAY BEFORE EVENTUALLY LIFTING BACK TO THE NORTH AS A WARM FRONT WEDNESDAY INTO WEDNESDAY NIGHT.
THE OVERALL LARGE SCALE WEATHER PATTERN CURRENTLY FEATURES A SPRAWLING RIDGE OF HIGH PRESSURE THAT HAS SETTLED OVER THE SOUTHEASTERN US. AND A LARGE TROUGH OF LOW PRESSURE THAT IS CURRENTLY SPINNING ITS WAY SLOWLY EASTWARD INTO THE WEST CENTRAL PLAINS. THIS TROUGH WILL BE WHAT FINALLY BRINGS RAIN BACK TO EASTERN KENTUCKY FOR THE LATTER HALF OF THE WEEK. TODAYS HIGHS ARE AGAIN EXPECTED TO BE WELL ABOVE NORMAL AS A RIDGE OF HIGH PRESSURE REMAINS ENTRENCHED ACROSS THE SOUTHEASTERN CONUS. AS AN AREA OF LOW PRESSURE APPROACHES FROM THE WEST. ALONG WITH THE PASSAGE OF A VERY WEAK WARM FRONTAL TYPE OF A BOUNDARY. UNTIL THE COLD FRONT ASSOCIATED WITH THE AFOREMENTIONED UPPER LEVEL TROUGH MOVES INTO THE AREA LATER IN THE WEEK.
HOWEVER BETTER CHANCES STILL EXPECTED FURTHER EAST WITH IN VICINITY OF THE TROUGH AXIS. RH FIELDS NOTING LOW STRATUS TO BE IN PLACE ACROSS THE CWA THROUGH MUCH OF THE MORNING AND COULD START TO SEE SOME BREAKS IN THE STRATUS THIS AFTERNOON ACROSS THE WESTERN CWA WITH SOME SUBSIDENCE AND THE WARMER APRIL SUN HELPING TO ERODE IT AS WELL. OVERALL TEMPERATURES TO STILL REMAIN A LITTLE COOLER IN THE MID 60S TO AROUND 70 FOR HIGHS DUE TO THE LINGERING CLOUD COVER.
A weak cold front will also move into/dissipate over the region after midnight and may provide a low level boundary for additional development. Despite stronger instability in southern sections, most of the models do indicate a better chance of storms over northern sections, along and north of a Sterling City to San Angelo to San Saba line, in the presence of stronger upper divergence and weak surface cold front.
UPPER LEVEL LOW OVER THE CENTRAL ROCKIES MOVING SLOWLY EAST INTO THE CENTRAL PLAINS. WARMER DAYTIME HIGHS COMPARED TO THE PAST COUPLE OF DAYS. UPPER LOW CONTINUES EAST FROM THE CENTRAL PLAINS INTO THE MIDWEST WEDNESDAY. WITH A LONG WAVE RIDGE BUILDING ACROSS THE ROCKIES. SAID RIDGE BUILDS SLOWLY EASTWARD INTO THE PLAINS STATES BY THE EARLY WEEKEND.
1032 AM EDT TUE APR 19 2016 UPDATE COOLER AIR HAS MOVED INTO SOUTHWEST MICHIGAN AN WILL REMAIN OVER THE AREA INTO THE WEEKEND.
INVERTED TROF OVER LAKE MICHIGAN CREATING LOW LEVEL CONVERGENCE AND WITH LOW TEMPERATURE.
735 AM EDT TUE APR 19 2016 A COLD FRONT WILL MOVE THROUGH EARLY THIS MORNING.
