549 AM CDT MON JUN 6 2016 Early this morning a broad upper trough of low pressure covered much of the Eastern half of the country in combination with a previous upper low that extended along the Western Louisiana and Texas coast have provided a shear axis across parts of the Southeast States, Louisiana and off the Texas coast. Another cold front will move across the forecast area on Tuesday providing a re-enforcing shot of dry air with no expected rainfall. The upper level ridge axis over the Western sections of the country will shift east during the week with a weak upper low along the South Texas coast riding under the ridge and once the upper ridge axis shifts east of the forecast area.
131 AM EDT MON JUN 6 2016 Low pressure stalled north of lake huron will pull a series of cold fronts southeast across the region through tuesday.
The highest winds are expected on our western and northwestern waters today into tonight, and more uniform beginning tomorrow.
507 AM EDT MON JUN 6 2016 Cold front remains northwest of the forecast area with Tropical Storm Colin moving northward in the southeastern Gulf of Mexico. The cold front will cross the area late Tuesday morning with TS Colin accelerating away from the area Tuesday afternoon. Drier air will move in behind the cold front with dry weather expected through the weekend.
558 AM EDT MON JUN 6 2016 Scattered showers and cooler temperatures can be expected into the middle of the week. That could lead to more than one cell tracking over a similar area before the boundary finally starts to get kicked to the SE as the upper trough settles southeastward by Monday night. The best chances for showers and thunderstorms seem to be pointed toward this evening as the jet streaks overhead strengthen and the mid-level trough axis approaches. By 12z, the mid-level trough and axis of the jet streak will have passed to our east, essentially ending the threat of showers and thunderstorms. Fries The dominant feature of the mid-week will remain the pinwheeling closed low pressure system centered near James Bay Canada.
352 AM CDT MON JUN 6 2016 An upper level trough developing over the Great Lakes will push a weak cold front into western Kansas late this afternoon and then to the KS/OK border by Tuesday morning.
There was a nearly stacked low near the border between Ontario and Quebec, and its cold front trailed west through Ontario into Manitoba. A cold front will also drop through the Northland Monday. The cloud cover and cool/humid air will likely limit highs to only the upper 50s and lower 60s, but it will feel even cooler because of the wind. The high pressure and dry air/low dew points will allow for a cool night Tuesday night. A return to southerly flow, along with a warming trend, arrives for the later half of the work week as an upper level ridge builds over the central plains.
A cold front will move into the area Monday afternoon, possibly causing isolated to scattered thunderstorms. except a bit cooler near Lake Michigan. Cooler temperatures and mainly dry conditions are then expected into midweek as high pressure builds in. trof mon ngt-tue ngt keeping a threat of showers in the area.
Expect to see the typical summer weather pattern along the coast with morning low clouds and fog followed by a few hours of sunshine before the low clouds and fog return for the evening.
Reinforcing cold fronts late Monday and again late Tuesday night.
327 AM CDT MON JUN 6 2016 A band of positive vorticity advection will swing across the area today in conjunction with the upper low centered over Hudson Bay. Lower confidence late in the weekend for precipitation chances as a backdoor cold front lies near the region.
150 AM EDT MON JUN 6 2016 An approaching cold front will stall near the forecast area Monday. Low pressure from the Gulf of Mexico will track northeastward off the southeast coast Tuesday ahead of another cold front approaching from the northwest. The cold front will move through the area Tuesday night followed by a drier air mass remaining in place through late this week. An approaching cold front and a tropical storm moving out of the Gulf of Mexico will bring unsettled weather for the short term. The cold front will move into the Upstate early Monday and likely stall over the area. Moisture will be deep ahead of the slow moving cold front and upper trough to our west.
This activity continues to slowly drift west along the northern periphery of an upper trough centered over Southeast Texas. These trends should continue through the night as a quasi-stationary cold front moves slightly farther southeast allowing surface winds to become northerly, which will advect drier low-level air into the region from the northwest.
Water vapor imagery showed a pacific upper low in N NV undercutting a western U. upper ridge. Plenty of moisture was N of the low, based on satellite imagery, and showers and thunderstorms were occurring over E OR/S ID/N NV early this morning. Other isolated thunderstorms developed over the high terrain of W WY last evening, but nothing occurred over the forecast area. The east flow will limit mixing, so expect a cooler day with highs in the mid 70s to lower 80s. It will be a warmer day, however, highs will be limited by the amount of convection that develops during the afternoon.
Above average temperatures will persist through Tuesday, with breezy and cooler conditions for the second half of the week as low pressure moves into the west. Storms could also develop in northeastern Pershing County where cooler air aloft remains near the exiting cold pool and a final wave of forcing may be enough to initiate isolated storms later in the afternoon.
A weak upper low centered over Nevada will move slowly east across Utah tonight through Tuesday. High pressure aloft will strengthen once again across the Great Basin midweek.
124 AM EDT MON JUN 6 2016 A cold front crosses the region late tonight.
The ridge of high pressure continues to be the dominant feature over the Northern Rockies causing extremely warm temperatures. A weak disturbance trapped under the ridge of high pressure will gradually make its way northward today through Tuesday.
602 AM EDT MON JUN 6 2016 Reinforcing cold fronts late today and again Tuesday.
629 AM EDT MON JUN 6 2016 A cold front will drop south from the Great Lakes today bringing another chance for showers and thunderstorms.
Upper low will track across northern NV today keeping shower and thunderstorm threat across most of the region.
411 AM CDT MON JUN 6 2016 An active northwesterly flow pattern aloft is expected across the Panhandles fore the next few days as an upper ridge builds over the southwestern states northeastward across the four corners region into the central Rockies.
a stronger cold front is diving southward across the great lakes. However, the main focus for the short term will be the cold front to the north. Forcing and instability will be considerably less to the south and convection will outrun the cold front. Cold front will continue pushing south tonight, but moisture will be lacking. The front will exit southeast early Tuesday, with cooler and less humid conditions spreading into the region.
The warm and sunny conditions will be short-lived however, as a large upper low shifts from Ontario southeastward to over the North Country for the mid-week period.
Northerly flow will continue overnight, with drier air pushing into the western zones on the back side of this low.
High pressure will gradually weaken and shift east allowing temperatures to moderate through mid week.
118 AM EDT MON JUN 6 2016 A cold front along the western slopes of the Appalachians will move east across the region this morning and off the coast by this afternoon. A second cold front with an associated stronger push of drier and cooler air arrives Tuesday into Tuesday night.
320 AM PDT MON JUN 6 2016 Slightly cooler today as a weak low pressure system moves through northern and central California.
335 AM EDT MON JUN 6 2016 Relatively tranquil weather is expected today in the wake of the cold front which moved through last evening. The next cold front will propagate through through the region tomorrow.
Several feet of storm surge inundation is expected along parts of the Apalachee Bay coastline on Monday afternoon during the high tide cycle. Surge near the higher end of the forecast range (around 4 feet) would be more likely if the center of Colin tracks further northwest than the official forecast track from NHC. It would also likely lead to surge near the higher end of the current forecast range along the Apalachee Bay coast, particularly near the rim of the bay from Wakulla County into northern Taylor County.
256 AM MDT MON JUN 6 2016 Strong upper ridging will remain across the wrn CONUS through the short term. Slightly cooler air is expected across the area today as a backdoor cold front pushes into the wrn SD plains. This will bring warmer temps with highs reaching the 80s across most area. An isolated thunderstorm or two will be possible across the Black Hills Tues afternoon as soundings show a weak cap across the higher terrain and CAPE reaching around 1400 J/kg.
337 AM CDT MON JUN 6 2016 A very ill-defined cold front extends from central Virginia southwest to near Murfreesboro and just south of Memphis in Tennessee. Primarily, near and south of a line from Bridgeport, to Scottsboro and Hartselle. Drier air and cooler air will push into the Tennessee Valley behind the front overnight tonight into Tuesday morning, dropping temperatures a bit. Highs in the lower to mid 80s look reasonable on Tuesday with lows Tuesday night dropping into the lower to mid 60s. Much cooler and drier air is on the way later on Tuesday as another weak cold front moves southeast through the Tennessee Valley. Stronger northwesterly flow behind this front Tuesday night will bring much cooler/drier air into the area. dropping low temperatures into the lower 60s.
1205 PM EDT Mon Oct 24 2016 High pressure will return to the region through midweek.
Moderating temperatures will result in readings near average with highs ranging from the mid 70s coast to the lower 80s inland.
Highs in the lower 80s will prevail this afternoon, along with light northwesterly winds under mostly sunny skies.
Deep layer ridging centered over the southeastern US will maintain light northerly flow over the area today. Drainage flow from the mainland will veer onshore this morning and allow temperatures to moderate into the upper 70s over much of the area, save for the immediate coast where highs will be a few degrees cooler. High pressure extending eastward across the Southeast U.
1015 AM EDT Mon Oct 24 2016 A cold front and potent disturbance aloft will pass through tonight and early Monday bringing a cold rain to the northern half of the state. Temps will be cooler and in the 40-45F range for overnight lows across the north where the steadier rain falls (and cfropa occurs earlier), while mins in the south will be mainly in the upper 40s. High pressure stays to the W thru the short- term and the tight pres grad will keep it breezy. The flow lasts into Mon Night, and the temps get cold enough then to get a mix or plain ol' --sn for precip type in the higher elevation of the nrn mtns. CAA comes to an end on Wed as weak progressive upper ridge moves through as low-level flow turns back to the S/SW.
1026 AM EDT Mon Oct 24 2016 High pressure remains the dominant weather feature across the region. Temperatures will come in just a couple of degrees warmer than yesterday, with highs near 80 degrees across all of west central and southwest Florida. Breezy northeast winds will continue the next couple of days as high pressure remains just north of the area. and off the Atlantic coast Tuesday, allowing strong high pressure to build in across the Mid- Atlantic. The gradient looks to weaken slightly this weekend as high pressure slips southward over the northern waters with improving marine conditions.
1030 AM EDT Mon Oct 24 2016 Cooler temperatures today with a few sprinkles or a shower, especially north and east of Pittsburgh.
930 AM PDT Mon Oct 24 2016 The widespread thunderstorms over Orange, western Riverside and southwestern San Bernardino Counties have decreased in intensity, and just scattered showers and isolated thunderstorms will continue through this afternoon under the trough of low pressure.
A cold front will bring rain and gusty winds that will spread across the area this morning. Models show this low dropping to around 970 MB. This will continue to move to the north, but is bringing a cold front to our area. As of 230 AM this cold front is about 60 miles offshore. Tuesday night a warm front moves by the area coming from the southwest. Right behind this warm front is a cold front.
A gradual warming and drying trend will begin midweek as high pressure aloft strengthens across the Great Basin. Water vapor loop shows southwest flow aloft between a cold closed low over off the Pacific Northwest coast and a strong ridge over Texas. A vorticity lobe rotating northeast across the Pacific Northwest and western Great Basin later today will continue to pump moisture across western/northern Utah and nudge somewhat cooler air aloft into northern Utah this afternoon/evening. Light convective precip should linger across northern and eastern Utah into Tuesday morning, then decrease fairly quickly as heights begin to rise across the Great Basin in response to the deepening of the upper trough over the eastern Pacific.
Shifted some of the higher chances of precipitation over the Snake Plain this afternoon based on apparent track of showers in satellite imagery and the 12Z NAM model run.
Snow levels will be high limiting accumulation to just the highest peaks.
Mainly cirriform clouds were spreading ewd/newd across southeast AZ ahead of a deep upper trough near the West Coast.
753 AM EDT Mon Oct 24 2016 A cold front will exit southeast this morning, with cooler temperatures through the day.
Maliawco Today will be another mild day with a long-wave upper ridge in place with the axis over Montana. The ridge is currently anchored by a broad area of high pressure centered around Texas. However the broad trough in eastern Canada will exercise some minor influence for us - tempering temperatures to around normal today. The closed low Pacific storm system swings north along the Northwest coast and will be off Vancouver Island Monday night and Tuesday. The trough movement will effectively push the local ridge axis east of Montana. Expect another pleasant Fall day with highs a bit warmer than Monday.
713 AM CDT MON OCT 24 2016 Quiet and much cooler weather conditions expected across central and southeast Illinois through the period.
616 AM CDT Mon Oct 24 2016 High pressure ridge builds in over the central conus resulting in a modest rebound in temps on Tuesday. Expect TSRA then to develop along lifting warm front within llvl theta-E convg zone.
726 AM EDT Mon Oct 24 2016 Aviation Issued at 320 EDT Mon Oct 24 2016 High pressure building into Lower Michigan should bring fair and cool weather today and Tuesday.
904 AM EDT Mon Oct 24 2016 High pressure will remain over the Southeastern United States today keeping an northeast wind flow over South Florida along with dry weather.
945 AM MDT Mon Oct 24 2016 Ridge axis was positioned over eastern Montana this morning with southwest flow aloft over western areas. High pressure ridging will continue for the most part across the northern Rockies through Tuesday. A large upper low off the Pacific northwest coast will provide a southwest flow aloft across southern Montana today. Temperatures will remain above normal with readings in the lower to middle 60s for most areas today with middle to upper 60s expected on Tuesday.
1101 AM EDT Mon Oct 24 2016 Changes to Forecast -- We updated both the digital database and derived forecasts to account for breezier, cloudier, and slightly cooler conditions this afternoon. High pressure centered over the southeastern United States will be reinforced by a large high pressure system spreading across the eastern United States.
/issued 330 AM CDT Mon Oct 24 2016/ Temperatures are quite a bit warmer this morning than we have seen the past couple of days. A weak cold front will move across the region today. but largely go unnoticed as the airmass behind the front is only slightly cooler than what is currently in place. Over the next few days a broad ridge will shift from over the Plains, approaching the Mississippi river Valley late Tuesday.

A ridge over much of the central U. Even with the warming 850 temps, lows will get to similar values as previous nights, in the lower to upper 40s. This will advect slightly cooler air into the region and keep highs around 80 but down into the middle 70s in NE Alabama and southern middle TN.
552 AM MDT MON OCT 24 2016 12Z TAF CYCLE Isolated showers and thunderstorms should begin moving into western areas this afternoon as a short wave trough aloft approaches the Four Corners from the SW. Ridge of high pressure has shifted just east of NM as a weak short wave trough ejects east out of a potent storm off the Pacific Northwest. This trough will lift northeast and only provide rain chances across the northwest third or so of the forecast area.
733 AM EDT Mon Oct 24 2016 A cold front and potent disturbance aloft will pass through tonight and early Monday bringing a cold rain to the northern half of the state. Temps will be cooler and in the 40-45F range for overnight lows across the north where the steadier rain falls (and cfropa occurs earlier), while mins in the south will be mainly in the upper 40s. High pressure stays to the W thru the short- term and the tight pres grad will keep it breezy. The flow lasts into Mon Night, and the temps get cold enough then to get a mix or plain ol' --sn for precip type in the higher elevation of the nrn mtns. CAA comes to an end on Wed as weak progressive upper ridge moves through as low-level flow turns back to the S/SW.
1101 AM CDT MON OCT 24 2016 High pressure dominates the weather across central Illinois this morning. with readings topping out in the lower to middle 60s. Quiet and much cooler weather conditions expected across central and southeast Illinois through the period.
The main precipitation band associated with a cold front is along the northwest California coast, and will gradually shift inland today and tonight to the souteast.
1248 PM EDT Mon Oct 24 2016 Another cold front will move through the area this evening with a reinforcing shot of cool air through Midweek. just some high thin clouds streaming east from short wave trough in the southern stream over east Texas. A cold front currently over central Virginia will move south through the region this evening between 03z-06z. The forecast area will be situated between a broad upper ridge over the center of the country and broad trough off the east coast which will promote northwesterly flow aloft. High pressure will ridge into the forecast area from the northwest at the surface. Slightly below normal high temperatures are forecast, in the lower to middle 70s. An upper ridge over the center of the country will promote northwesterly flow aloft over the southeastern states through mid week.
634 AM CDT Mon Oct 24 2016 Early this morning a very weak cold frontal boundary was positioned along the I70 corridor in central Missouri. Today will be a tad cooler than yesterday, especially across the eastern Ozarks as a very slightly cooler air mass filters in from the north. The bulk of "cooler" air should remain across the mid Mississippi River and Ohio River Valleys as the Canadian high drops south and east across the Great Lakes and into the Mid Atlantic. Although cooler temperatures are forecast, we did go a degree or two above guidance in the short term because of the recent cool bias among short term models. An upper level ridge remains in place across the plains. Overnight, southerly flow will keep temperatures warmer, especially across southeast Kansas.
932 AM EDT Mon Oct 24 2016 A cold front will continue to move south of the area this morning. A high pressure ridge will slowly build southeast across the western Great Lakes region by Tuesday morning.
518 AM MDT Mon Oct 24 2016 Early morning WV imagery and RAP analysis shows large scale ridging continuing to dominate the pattern across the central US. At the surface as front is stalled along the front range, with high pressure centered over the northern Mississippi River Valley extending south and west towards our CWA.
1053 AM EDT Mon Oct 24 2016 Update/Marine Issued at 320 EDT Mon Oct 24 2016 High pressure building into Lower Michigan should bring fair and cool weather today and Tuesday.
1152 AM CDT Mon Oct 24 2016 Quiet conditions reign across the region early this morning, with upper air data showing northwesterly flow in place, as a ridge axis extends through the Rockies. At the surface, winds are light, thanks to high pressure building in from the north. Models remain in good agreement showing this upper level ridge axis gradually sliding east with time, keeping things dry across the CWA. A slightly cooler airmass in place is expected to keep afternoon high temperatures in the 60s across the CWA. The overall pattern is an upper level ridge over the plains.
1219 PM EDT Mon Oct 24 2016 High pressure will continue south of the region through today. A dry cold front will move through tonight followed by high pressure through the middle part of the week.
1029 AM CDT Mon Oct 24 2016 Updating forecast to add a slight chance for elevated showers Today over most of the CWA owing to the weak upper trough moving across the Region and mid/upper level moisture (also NQI recently reported -RA). As the trough moves farther to our our northeast northwest flow aloft kicks in, albeit brief, and helps to steepen the lapse rates with weak cold pool interaction, so more cloud cover is expected today. Continued onshore flow will help to increase the low-level moisture for tonight and when combined with the increase cloud cover, not allowing for deeper mixing, moisture will be able to pool nicely tonight.
1051 AM EDT Mon Oct 24 2016 High pressure will return to the region through midweek.
A weak cold front will move through Middle Tennessee today. High pressure will begin to build in from the Ohio Valley this afternoon. Winds will shift to the north but remain light and high temps along the KY border will be a degree or two cooler than yesterday. Highs will range from the lower 70s north to upper 70s south. A dry cold front will drop southward across Middle Tennessee today, bringing only a few high clouds and a wind shift to the north. Expect cooler temperatures overnight, but also falling dew points with drier air advecting in, so we're looking at VFR wx the next 24 hrs.
1027 AM CDT Mon Oct 24 2016 FOR MORNING DISCUSSION High pressure in place across the region will continue to result in dry quiet weather today. Conditions will be a tad warmer than those from the previous few days, as highs this afternoon range from the upper 70s to middle 80s. High temperatures will climb into the low 80s this afternoon under mainly high clouds. The main concern for today will be the low Rh's this afternoon. High pressure will continue into tonight, with slightly warmer overnight lows in the mid/upper 40s.
1217 PM EDT Mon Oct 24 2016 A cold front will continue to move south of the area this morning. A high pressure ridge will slowly build southeast across the western Great Lakes region by Tuesday morning.
