324 PM CDT WED MAY 11 2016 Cold front is finally exiting the area with only small lingering chcs for convection across the far southeast counties this evening. The upper trough will remain over the region with another wave forecast to move across the region tonight with additional lift in the 800-500mb layer. A dry and quiet day should prevail across the area on Thursday with highs in the lower to middle 70s along with dewpoints in the 40s.
241 PM EDT WED MAY 11 2016 High pressure will provide one more day of nice weather, before a storm system sliding out of the Great Lakes spreads showers and cool temperatures across our region.
345 PM EDT WED MAY 11 2016 The area will remain situated between Atlantic high pressure and a piedmont trough through Thursday.
251 PM EDT WED MAY 11 2016 High pressure will provide one more day of nice weather on Thursday, before a storm system sliding out of the Great Lakes spreads showers and cool temperatures across our region.
315 PM EDT WED MAY 11 2016 The afternoon regional surface analysis shows the ridge axis has shifted ever so slightly to the south with residual dry air marked by dewpoints in the upper 50s continuing to reside over central Georgia.
138 PM PDT WED MAY 11 2016 Dry and warmer weather through Thursday, with night/morning low clouds along the coast.
A COLD FRONT WILL BE MOVING TOWARDS THE I-30 CORRIDOR OF NE TX/SW AR/SE OK THURSDAY MORNING AND HAVE INTRODUCED VCTS TO THE TYR/GGG/TXK TERMINALS ACCORDINGLY IN THE 14-18Z TIMEFRAME.
For this evening, a cold front, currently stretched across central and southeast Oklahoma, is expected to push a little further into southeast Oklahoma. Along and ahead of the cold front, convective iniation is expected to occur in the moister and unstable air toward and during the evening hours. After midnight, an upper wave digging across the high plains may generate a few additional thunderstorms beginning in Northwest Oklahoma. However, much of of area will be well behind the cold front, with less moisture to work with in a much lower unstable environment.
1140 AM PDT WED MAY 11 2016 updated aviation section UPPER-LEVEL RIDGING WILL PERSIST ACROSS THE REGION DURING THE NEXT FEW DAYS.
246 PM CDT WED MAY 11 2016 The 19z surface analysis indicated that the nearly stationary frontal boundary/warm front was extending into middle and southeast Tennessee from southwest Kentucky. A cold front is progged to be moving through the midwest tonight and should make it southeast to the Ohio river by between 12z and 18z Thursday. Model forecast soundings indicate that the forecast area should become moderately unstable by Thursday afternoon as a pre-frontal trough is expected to develop to the west of the area.
The area of low pressure that is bringing this rain will slowly move across MN tonight and into the northern Great Lakes by thursday evening. 30 with the higher amounts in nw WI. The rain will taper off to showers Thursday morning as the low moves east but it will stay cloudy most of the day.
319 PM EDT WED MAY 11 2016 high pressure across the area will bring keep it dry through thursday.
238 PM CDT WED MAY 11 2016 An upper level trough is over the Northern Plains with westerly flow over the area. As the upper trough continues to move eastward overnight, a cold front will begin pushing into the area early Thursday morning providing even more lift. Temperatures will be about 10 degrees below normal tomorrow behind the cold front and the best storm chances during the afternoon will be along and south of the Lower Trans Pecos. High winds may briefly occur through Guadalupe Pass Thursday morning as the front moves through but do not anticipate the high winds to last long enough to warrant issuing any high wind product at this time.
ACROSS THE PLAINS, LOW LEVEL FLOW WILL SHIFT OUT OF THE EAST TO SOUTHEAST BY AFTERNOON BEHIND THE COLD FRONT WHICH MOVED THROUGH THE REGION YESTERDAY EVENING. STILL SOME RESIDUAL ENERGY DROPPING THROUGH NW FLOW ALOFT ON BACK SIDE OF THE TROUGH TONIGHT WHICH MAY KEEP SHOWERS GOING THROUGH THE FIRST HALF OF TONIGHT BEFORE FINALLY SHIFTING EASTWARD. LOOKS LIKE TEMPERATURES WILL JUST TOUCH OR NEAR THE FREEZING MARK IN ONLY SPOTTY AREAS RIGHT NEAR DAWN, SO EVENT LOOKS TOO SPOTTY AND BRIEF TO WARRANT ANY FROST OR FREEZE HIGHLIGHTS AT THIS TIME.
Storm coverage should increase as a cold front moves into West Central Texas this evening, with the chance of storms spreading south towards the southern terminals by sunrise. That's where a weak cold front will begin to move into West Central Texas later this afternoon.
652 PM EDT WED MAY 11 2016 High pressure will provide one more day of nice weather on Thursday, before a storm system sliding out of the Great Lakes spreads showers and cool temperatures across our region.

546 PM EDT WED MAY 11 2016 Temperatures will trend modestly warmer through the end of the week.
354 PM EDT WED MAY 11 2016 Temperatures will trend modestly warmer through the end of the week.
Otherwise the big story is a cold front which will migrate across area terminals in the 10Z-14Z time range. Winds will be light out of mostly the south to southwest today before a cold front moves into the area around 12z Thursday. Mid level thermal ridging will again lead to highs about 10 degrees above normal today. Meanwhile, an upper level trough will move across the Plains today sending a strong cold front south.
/issued / The latest regional surface analysis shows high pressure in control from the sandhills of the Carolinas through central and south Georgia. THIS LINE IS ASSOCIATED WITH THE WEAKENING FRONTAL SYSTEM TO OUR NORTH AND WEST THAT WILL CONTINUE TO ROTATE AROUND THE HIGH PRESSURE RIDGE THAT IS NOSING INTO THE SOUTHEASTERN U. BOTH MODELS PUSH A COLD FRONT INTO NORTH GA THURSDAY EVENING.
453 PM EDT WED MAY 11 2016 High pressure will dominate through the period.
1218 PM CDT WED MAY 11 2016 Latest water vapor imagery shows a stacked mid/upper low circulation over north central North Dakota, near Minot Air Force Base early this afternoon. A couple of 850mb cold pockets (thermal troughs) were rotating around the stacked low and into western and north central North Dakota this afternoon. Looking ahead, despite some scattering in the clouds this afternoon, another area of stratus will slide from northwest to southeast tonight which is associated with an 850mb thermal trough nosing into western and central North Dakota.
For today, a vorticity lobe on the bottom of an upper low will move across the Central Plains later tonight. Highs today will be in the low to mid 70s with increasing clouds in the far west late. North to northwest winds of 15 to 30 mph this morning settle back in the afternoon as high pressure build into the Central Plains.
We anticipate that thunderstorms will develop northwest of the metroplex TAF sites late this afternoon along an approaching cold front. The most likely time for impact at the metroplex terminals will be late this evening generally between about 04Z and 07Z when storms move off of the cold front. There should be a lull in activity overnight until the cold front moves through toward sunrise Thursday. The passage of the cold front will also turn the wind to the north at speeds between 6 and 12 knots.
A cut-off low along the British Columbia will be decaying and getting absorbed into another low pressure system approaching the Pacific Northwest coast.
SLOWLY LIFTING NORTH INTO CANADA WITH TRAILING TROUGH THROUGH THE CENTRAL PLAINS BY 00Z.
However, given the low confidence on storm strength and evolution, will hold off on a flash flood watch for now. We may see another lull in activity tomorrow, which will allow highs to reach the low 80s. A cold front advancing in from the northwest will then push across Kentucky Thursday evening. Looks like the main threats would be large hail and damaging winds with the low level shear not sufficient enough to support a tornado threat.
Overnight, convection should initiate in Missouri and move southeast along the warm frontal/residual outflow boundary. Southwest winds will pick up after 14z Thursday, and VFR conditions will be expected until showers/storms move in along an approaching cold front, but that's beyond this 24-hour TAF period.
A similar story on Thu with weakening high pressure and development of an onshore breeze by mid day. RH values wl increase through the period as the ridging aloft weakens.
Tonight, pressure gradients relax as ridging briefly settles in ahead of the next system Thursday evening.
129 PM EDT WED MAY 11 2016 The area will remain situated between Atlantic high pressure and a piedmont trough through Thursday.
A cut- off low along British Columbia will be decaying and getting absorbed into another low pressure system approaching the Pacific Northwest coast.
The latest water vapor imagery details a closed mid/upper level low circulating over north central North Dakota. This low is forecast to eject into Manitoba tonight, and then dumbbell around Ontario over the weekend. Visible satellite imagery and surface observations reveal a wide swath of strato-cumulus clouds associated with a low level cold/moist pocket of air underneath the large upper low. For the short term period tonight through Thursday, scattered rain showers across north central North Dakota will slowly shift into the Turtle Mountains tonight in association with the movement of the upper low.
but that certainly has not dampened the low level moisture across the region (dewpoints in the 60s and 70s). A cold front still on track to impinge on the region tomorrow late afternoon/early evening.
245 PM MST Wed May 11 2016 A high pressure system will build into the region for a significant warming trend through the end of the work week.
/ISSUED 1034 AM CDT WED MAY 11 2016/ A fairly stationary warm front has setup from extreme western kentucky east-southeast into the Crossville and Jamestown areas in northern Tennessee. Models do show another meso-low developing later this afternoon over extreme western Kentucky upstream of the area and along the warm front.
223 PM EDT WED MAY 11 2016 High pressure will continue ridging from off the Southeast Coast westward along the Gulf Coast through Thursday. The ridging has limited moisture in the forecast area. Moisture will increase in the area ahead of a cold front approaching from the northwest.
Warming trend is expected to peak on Thursday with high temperatures in the upper low to mid 90s for portions of the Central Valley. After Thursday, the ridge currently over the west coast shifts eastward over the Rockies and the next trough approaches the area.
Cooler air will settle in behind the disturbance with overnight lows dropping into the mid 30s to lower 40s across the eastern plains. the upper level disturbance will continue to the east as high pressure over the Great Basin shifts eastward. Generally clear skies will combine with warmer air advecting into the region to produce a pleasant day across Colorado. Highs will top out in the lower 70s across the plains.
127 PM EDT WED MAY 11 2016 A ridge of high pressure will reamin over the north country today through late thursday, resulting in plenty of sun and warm temperatures.
At the start of this forecast period a cold front will be nearing the Miss River.
343 PM MDT WED MAY 11 2016 This morning's mid level hand analysis showed a fairly deep trough swinging across the northern plains with cooler air being re-enforced across the Rockies and Inter-mountain West. Normally the coldest air will be found with this high but drier air invading from the Southwest will help temperatures in the 4 Corners region drop steadily after sunset. Expect freezing temperatures to affect portions of Montezuma County where sensitive vegetation could temporarily be at risk so have hoisted a freeze warning above 5500 feet. A warmer and drier weather pattern will then be setting up to end the week with an upper ridge building across the west and translating toward the Rockies. Lows will also be moderating Thursday night with freezing temperatures in the lower elevations not a concern.
332 PM EDT WED MAY 11 2016 High pressure will provide one more day of nice weather on Thursday, before a storm system sliding out of the Great Lakes spreads showers and cool temperatures across our region.
The storms will generally move to the east, but increasingly easterly component to the low-level flow may allow for some redevelopment back to the west through the evening. After midnight, a cold front, possibly enhanced by t-storm outflow, will move south through our forecast area. Thursday's highs should only reach the lower to middle 70s for most locations. 12Z guidance is still on track favoring unsettled conditions this weekend in the vicinity of a decaying upper ridge.
An upper ridge extending across the central Gulf of Mexico has flattened considerably since yesterday. The surface pattern though, remains largely unchanged, with high pressure remaining firmly in control.
Showers immediately surrounding the low may clip northern areas tonight so will maintain some low pops. Farther east, band of shra in zone of lower condensation pressure deficits, low level convergence, and impulse ahead of the low weakening and shifting east. Clouds currently showing more cumulaform nature so could see some clearing south of the low. Column does not cool off much and should see enough mixing to hold temperatures up into the low/mid 40s. Short wave rotating around upper low will continue to warrant low end pops with best chances to our south.

LOW PRESSURE CENTERED OVER OHIO WILL MOVE ON TO THE EAST.
THE EXPECTED COLD FRONT HAS BREACHED NORTHERN MISSISSIPPI. THE OVERALL TREND WITH THE OMEGA BLOCK IN PLACE MEANS A LIKELY CHANCE OF THE COLD FRONT PERSISTING IN THE REGION LONGER THAN MODELS TEND TO PREDICT. THE CURRENT THINKING IS THAT PATCHY FOG WILL PERSIST UNTIL ROUGHLY 9AM AS WINDS WILL REMAIN LIGHT UNTIL THE PRESSURE TIGHTENS WITH THE APPROACH OF THE COLD FRONT. WITH THE LOW HITTING AROUND SUNRISE.
