354 AM EDT SAT JUN 4 2016 Today-Tonight: Not much change in the ongoing pattern for today, as we remain under the influence of ridging aloft and along the southern periphery of the Western Atlantic low level ridge.
showers and thunderstorms will return again this afternoon and continue through Sunday as low pressure moves a cold front through the region. Difficult to determine just how extensive these clouds will be through midday as the broad ridge axis and drier air aloft will be slow to move east. Showers and thunderstorms are expected to develop later today as the ridge slowly gives way to the approaching upper trough. Showers and thunderstorms will continue Saturday night, as low pressure works east into Sunday. A cold front will cross the region with widespread showers and storms Sunday, with near seasonal temperatures.
310 AM PDT SAT JUN 4 2016 The coastal marine layer will persist with high pressure overhead today for fair skies inland and hot conditions.
329 AM CDT SAT JUN 4 2016 The upper level trough digging southeast across the upper midwest will phase with the upper low across eastern TX and move into the MS river valley Tonight. The weak surface cold front will move southeast of the CWA during the mid morning hours of Saturday. Scattered CU will redevelop during the afternoon hours across northeast KS as lapse rates may be steep enough along the western periphery of the departing H5 trough. Highs Today will reach the lower 80s across much of the CWA. Meanwhile a strong ridge continues to build over the Western CONUS with impressive heights entrenched in place.
423 AM EDT SAT JUN 4 2016 Moisture will circulate into the forecast area on the backside of high pressure centered off the southeast coast and ahead of a cold front slowly approaching from the west.
308 AM MDT SAT JUN 4 2016 Another few days of high pressure, dry and warm conditions on tap.
Latest water vapor imagery and 500 mb heights featured two upper lows over the CONUS - one over east central Texas and the second over the Upper Midwest. With weak ridging off the SE coast, southerly flow in between has allowed anomalously high Gulf moisture to lift northward into the mid-Mississippi and lower Ohio Valley. A surface analysis had a weak warm front across Indiana and Ohio with dewpoints well into the 60s to near 70 across much of southern Indiana and central Kentucky.
350 AM CDT SAT JUN 4 2016 Early morning temperatures are in the low 70s across the Midsouth under cloudy skies. A deep trough remains in over the Mississippi River valley. This low will slowly sink to the south over the next 24 to 48 hours. and the mean trough will shift slowly to the East. West of the axis of the trough.
548 AM CDT SAT JUN 4 2016 Line of showers and thunderstorms along and just ahead of cold front extending from southeastern Iowa to Kirksville then southwest towards southern portions of KC metro area, is moving into more stable air/lower CAPES, so will continue to see a weakening trend through daybreak.
Slow moving upper low is currently over southeast Texas this morning. 13/MH Guidance still suggests that northern stream energy will be the kicker for this upper low as a cold front slides southward.
High pressure over the region will maintain very warm and dry weather conditions across inland areas into Saturday. A cooling trend will begin near the coast on Saturday and spread inland by Sunday as an upper level low pressure system approaches the coast and onshore flow increases.
357 AM CDT SAT JUN 4 2016 The upper low near Baudette will slowly propagate east through the period. although with upper level low further east showers should be limited to east of the valley.
Upper ridge building over the northern Rockies with trof moving into the upper Great Lakes. A weak wave drops across the Canadian prairies on Sunday pushing a backdoor cold front into northeast Montana. Main impact from this front will be a band of cloud and a little cooler temperatures for the northeast zones.
Temperatures range from the upper 70s to the lower 80s. An Atlantic ridge of high pressure will extend across central Florida today and tonight. An area of low pressure will form near the Yucatan Peninsula by Sunday. Winds will begin to increase Sunday afternoon as this area of low pressure becomes better organized.
131 AM CDT SAT JUN 4 2016 Cold front remains well west of Middle Tennessee this morning, extending from the Corn Belt into the southern Plains, with the upper trough situated just east of the surface boundary. Low height center is rotating over eastern Texas, with abundant moisture circulating around the low and a moisture plume running northeastward all the way to the Ohio Valley. Look for the surface flow and upper trough to push through on Sunday, thereby ushering in a long period of dry, cooler weather.
313 AM CDT SAT JUN 4 2016 Line of showers and thunderstorms along and just ahead of cold front extending from southeastern Iowa to Kirksville then southwest towards southern portions of KC metro area, is moving into more stable air/lower CAPES, so will continue to see a weakening trend through daybreak.
The upper level low was centered between San Antonio and Austin early this morning. At the surface a low as located across the Brush Country with trough near the Mid and Upper Texas Coast. on the back side of the upper level low which is moving south-southeast. Out of an abundance of caution, and with the low 1 hr Flash Flood Guidance over the region, we have elected to maintain the Flash Flood Watch for central and eastern areas through 7 PM this evening. By Sunday the center of the mid and upper level low will be located across Deep South Texas with an inverted trough extending up through the Coastal Bend and Coastal Plains.
346 AM CDT SAT JUN 4 2016 Weak cold front moved through the CWA during the overnight hours, initiating a thin band of elevated convection along its leading edge. The upper level trough to the north will continue eastward through the Great Lakes region and a broad ridge will build into the western US placing the Central Plains in a northwest flow regime through the end of the upcoming week.
An upper trough of low pressure will approach the Tennessee Valley late today and tonight. The upper jet will strengthen the low-level jet with 850mb winds increasing to 25-30kts late today through Sunday. Upper trough axis and frontal boundary will move across Sunday afternoon/early evening.
646 AM EDT SAT JUN 4 2016 An upper level trough will dig into the Great Lakes and Ohio Valley this weekend. A cold front associated with this feature will push through the region Sunday bringing another chance of showers and thunderstorms. Ahead of the trof, broad isentropic lift will bring a moist and unstable atmosphere into the region. The steady showers in the nw will hold temperatures down into the lower 70s, with locations in the se rising to around 80 degrees Tonight the H5 trof will continue se towards the fa. Temperatures will remain on the warm side with lows only dropping into the lower to mid 60s. On Sunday, upper trof swings through the upper Ohio Valley, along with a cold front.
showers and thunderstorms will return again this afternoon and continue through Sunday as low pressure moves a cold front through the region. Showers and thunderstorms will increase later today as a ridge slowly gives way to the approaching upper trough. Think the focus of today's development will be along our eastern ridges and across our western zones nearer to the digging upper trough. Could not rule out a few localized water issues, but think the primary flash flood threat resides along the ridges just east of Garrett and Tucker Counties. The best severe risk will lie to the east of the ridges, but a few more downpours will remain possible.
338 AM CDT SAT JUN 4 2016 Upper low over central TX continues to generate shwrs/tstms over a large portion of the srn states this morning. We may see some of this activity shift nwd into our region later this morning, but we will likely see less coverage today as the low opens up and phases with a trof moving across the Great Lakes region. Pops will continue to gradually decrease through Sunday as the trof shifts sewd. Nw flow aloft and high pressure at the sfc will bring dry and warming weather for the upcoming work week.
SHORT TERM (Today through Sunday): Models are in good agreement with the movement of the upper low through Sunday. Currently the center of the low is rotating over the Texas Hill country and continues to move SSW as deep ridge builds across the West. The low will be centered right over Deep South Texas Sunday. Forecast temps will be a bit below normal due to the the lower heights and thickness values along with high pops and clouds today and Sunday.
Light rain left over from yesterday evening will continue to lift north and out of the Highway 82 corridor this morning. This is as a result of the continued combination of diurnal heating in this warm moist and unstable airmass, and the addition of increased troughing across the region from the west. However, this lull isn't expected to last long as a cold front will begin making its run on the northern third of the CWA toward early Sunday morning. Sunday through Sunday night, showers and storms are expected to be ongoing along and ahead of the aforementioned cold front as it pushes southeast into and through the forecast area during the course of the day. That said, behind the front rain will come to an end as skies gradually clear and slightly cooler drier air advects into the CWA from the northwest.
317 AM CDT SAT JUN 4 2016 Today will be highlighted by an upper trough of low pressure moving across the northern and central MS valley. The cumulus will erode this evening leaving clear skies for the rest of tonight and lows in the lower to mid 50s. Sunday looks to be a warmer day with optimal mixing and warmer thermal profiles, as highs climb into the upper 70s to lower 80s.
showers and thunderstorms will return again this afternoon and continue through Sunday as low pressure moves a cold front through the region. Difficult to determine just how extensive these clouds will be through midday as the broad ridge axis and drier air aloft will be slow to move east. Showers and thunderstorms are expected to develop later today as the ridge slowly gives way to the approaching upper trough. Think the focus of today's development will be along our eastern ridges and across our western zones nearer to the digging upper trough. Could not rule out a few localized water issues, but think the primary flash flood threat resides along the ridges just east of Garrett and Tucker Counties. The best severe risk will lie to the east of the ridges, but a few more downpours will remain possible.
Water vapor imagery verified the presence of a strong upper ridge building into the region with very little moisture over the western U. Mixing will be at or below 700 mb today and with 700 mb temperatures around +8 degrees c, highs will reach the lower 80s in many areas. The upper ridge axis will be anchored over the Pacific NW on Sun. 700 mb temperatures will remain the same as today/s, and the result will be slightly higher temperatures in the lower to mid 80s.
1220 AM CDT SAT JUN 4 2016 /06Z TAFs/ An upper low, which has been anchored over Central Texas, has finally begun drifting to the south. It does appear that the better threat for showers and a few storms will be across eastern zones where weak lift ahead of the diffuse upper trough axis may occur.
An upper level ridge wl remain centered ovr the desert SW on Sat with northerly flow aloft ovr the forecast area, and some breezy northerly sfc winds ovr the far sern plains. Temps on Sat should be a little cooler. the upper pattern will feature an upper trough over the Missouri Valley and high pressure over the Great Basin with southern Colorado under broad northwest flow aloft.
144 AM CDT SAT JUN 4 2016 Mean northeasterly flow is occurring over the Panhandles early this morning on the northwest edge of slowly departing upper low currently over central Texas. A weak cold front forced by a northern stream wave now exiting the central/northern Plains will continue moving south across the area this morning. The post-frontal air mass is slightly cooler with only a small different in temperatures tomorrow expected in comparison to today. Mid-upper flow will become more northerly as western ridge amplifies and the central Texas upper low shifts further away.
649 AM EDT SAT JUN 4 2016 Moisture will circulate into the forecast area on the backside of high pressure centered off the southeast coast and ahead of a cold front slowly approaching from the west.

NW flow remains across the Dakotas on the ern edge of the ridge. With high pressure/ridging dominating the region. Not much change to the pattern is expected heading into Sunday as high pressure remains in control. Decent agreement with GFS/ECMWF with western CONUS ridge shifting into the plains for the middle/end of the coming week.
414 AM MDT SAT JUN 4 2016 The weekend remains dry with warming temperatures as the high amplitude upper ridge remains in place over the western United States and an area of high pressure at the surface drops south through the central high plains region on it's way to the southern plains by late Sunday.
635 AM EDT SAT JUN 4 2016 A weak cold front will stall near the coast today. Clouds will spread across the region tonight with rain and a few thunderstorms arriving for Sunday ahead of a warm front.

422 AM EDT SAT JUN 4 2016 An upper level trough will dig into the Great Lakes and Ohio Valley this weekend. A cold front associated with this feature will push through the region Sunday bringing another chance of showers and thunderstorms. Ahead of the trof, broad isentropic lift will bring a moist and unstable atmosphere into the region. The steady showers in the nw will hold temperatures down into the lower 70s, with locations in the se rising to around 80 degrees Tonight the H5 trof will continue se towards the fa. Temperatures will remain on the warm side with lows only dropping into the lower to mid 60s. On Sunday, upper trof swings through the upper Ohio Valley, along with a cold front.
Very light showers skirting far southeast and south-central parts of Oklahoma north of upper low. This coincides with passage of mid-level/H70 trough.
Overnight satellite and radar shows an upper low over Texas pushing moisture into southeastern US where a slight surface convergence is allowing light showers to progress through the western and southern portion of Central Alabama. This will allow the 850 low to weaken and open up into a trough, thus giving a slight reprieve from early this evening. /61/ Widespread rain and storms are possible today and tomorrow as a trof approaches from the west.
156 AM EDT SAT JUN 4 2016 A low pressure system approaching from the plains will tap moisture over the lower Mississippi Valley and bring a chance of showers south of route 30 late tonight. Fair wx will cont most of tonight as ridging across the region moves east. Potential for some periods of showers conts Sun-Tue as upr low moves slowly east across Ontario-Quebec with wk shrtwvs rotating around the low. High pressure should build in Tue ngt/Wed providing fair weather. Considerable differences in medium range models by next Thu-Fri with ECMWF suggesting more persistent ern North America trof while GFS is quicker to build rockies ridge east into the plains.
Should start to see some improvement to cigs late in the TAF period over NE TX/SW AR as drier air begins to entrain SE behind the upper trough axis as it shifts SE as well. Water vapor loops seem to support this as the dry slot is moved slightly farther east by the upper trough over Central Texas.
Strong high pressure will bring very warm temperatures through the weekend with highs in the mid 80s to the upper 90s. Ridge amplification continues for one more day over Nevada. The higher valleys will not be quite as hot with mid 80s to lower 90s. Slightly cooler readings will occur on Sunday as a closed low circulation moves over Sacramento valley. with the warm ridge shifting over to Utah. Moisture advection is not overly impressive in advance of the closed low, although precipitable water may approach one inch over Humboldt county and range between 0. Unsettled weather and very warm temps to start the week, turning drier and cooler late week.
