246 AM CDT Thu Jun 11 2020 Cold front has pushed well into Georgia this morning resulting in cooler and drier air being ushered in from the northwest. Temperatures this morning are about 10 to 15 degrees lower than they were yesterday at this time, sitting in the low to mid 60s. Plenty of sunshine is expected today with afternoon highs topping out in the lower 80s, but more importantly dewpts in the upper 50s will make it feel amazing outside.
This will help to bring plenty of sunshine and seasonal temperatures in the lower to mid 80s. Mid level flow will become more northwesterly on Friday/Friday night as a ridge of high pressure builds over the Plains and a secondary trof digs southeast into the Great Lakes region. However, any precip with the H50 trof is should remain well northeast of the forecast area. The upper-level ridge over the Plains will slowly advance eastward during the weekend, with progress limited due to a trough over the Eastern U.
Scattered to numerous storms expected this afternoon/evening over interior se GA ahead of a slow moving cold front. Convection will linger through the evening hours and possibly past midnight across se Ga due to the proximity of front and an amplifying upper trough approaching from the nw.
1006 PM PDT Wed Jun 10 2020 Expect warmer temperatures for the rest of the work week.
The remainder of the workweek will see upper level ridging building back over the Plains and temperatures climbing back into the mid 80s tomorrow and mid to upper 80s on Friday.
Sunny skies and highs in the low to mid 80s are expected for Thursday.
1045 PM MDT Wed Jun 10 2020 Western NOAM ridge will slowly push east as a NE PAC upper trough slowly advects east. This will support continued deep layer ridging over the area and a warming trend through the end of the work week. Quiet weather expected through Friday, with warmer temps each day. This will allow slight chances for showers and TS to return as the ridge shifts east and semi-active SW flow spreads into the region.
The main chance looks to be north of I-94, where mid/upper forcing will combine best with low-level forcing along the front/trough.
300 AM EDT Thu Jun 11 2020 Dry weather and seasonable temperatures are expected through the rest of the work week under building high pressure. A cold front should complete its passage early this morning, with just a band of clouds associated with it.
230 AM MDT Thu Jun 11 2020 500mb RAP analysis and satellite imagery showed a trough over the eastern CONUS with a ridge building to its west, placing the region under northwest flow. As the upper ridge progresses from the Great Basin to the eastern Rockies today and Friday, dry weather, sunny skies, and a warming trend are expected. High temperatures climb from the 80s today to mainly the low 90s on Friday.
Passing cold front now well east, and drier cooler air settling on the mid-state.
Some orographic convective towers have built up over the higher terrain, however the only notable development of these have been in the eastern Uinta range. Still, extremely dry soundings in the low and mid levels indicate that any convection should likely only produce virga today in this range. Another dry day is in the works for Thursday as a ridge of high pressure continues to build over the southwestern CONUS. Expect another night of clear and mainly calm weather on Thursday night as the ridge continues to build over the Four Corners. A deepening low pressure system will swoop inland across the Pacific Northwest on Friday. As a result, the ridge overhead will shift eastward while the pressure gradient tightens over the Great Basin.
404 AM EDT Thu Jun 11 2020 Under partly cloudy skies and light mainly east winds of 5 to 10 mph, temperatures are holding in the lower 80s along the Florida Keys. A trough of low pressure between Andros Island and the Northwest Bahamas will move westward and across our region today, before exiting into the Southeast Gulf of Mexico late tonight.
Current surface analysis place low over southern Ontario and ridge over the northern Rockies, resulting in breezy northwesterly winds over our area. Upper level analysis places trough along the Manitoba/Ontario border resulting in modest cyclonic flow over North Dakota. On Thursday, aforementioned trough scoots off to the east with ridge strengthening to the west. This will also result in warmer temperatures, with highs climbing to a bit above average. Ridging remains over the area on Friday keeping conditions dry.
/issued 1000 PM CDT Wed Jun 10 2020/ Looking at a quiet night on tap as high pressure builds in from the northwest under a large dome of high pressure. This high is expected to remain in place through the rest of the week and into the weekend. A dry north to northwest flow will be in place through the column between high pressure amplifying northward from Texas, and low pressure digging over the eastern CONUS. High pressure building over the region will maintain a dry weather pattern.
Winds have calmed considerably, as high pressure sits over the Texas Panhandle this afternoon. Given this, have updated winds to be on the lighter side (even by Panhandle standards) and ensured dew point temperatures near areas with active crops were closer to the lower 30s. VFR conditions under clear skies and high pressure will occur with winds being light and variable through 11/12Z. Winds will increase out of the south to south-southwest to around 10 to 20 kts due to the high progressing to the east of the region, and terrain induced pressure changes.
The warmer temperatures return today, as upper level ridging starts moving into the area with southwesterly surface flow. This will allow high temperature to reach the low to mid 80s today. Good news is dew points will stay in the 50s, so it won't feel warmer than the actual temperature.
By Friday, ridging will begin to regain control and allow temperatures to return to above normal. There is a weak trough that appears to want to come down into the northern portions of the region late Friday night and push against the ridge. The dry air and increased ridging will keep the rain chances low and are likely to keep rain out of the short term. Metzger The extended range looks to remain rather warm as ridging is expected to build into the region.
High pressure ridging continues today with much warmer weather into Friday. Valley highs are expected in the 80s today reaching the low 90s Friday. Enough moisture will sneak under the ridge to allow scattered high-based showers and a few thunderstorms to develop late this afternoon.
157 AM EDT Thu Jun 11 2020 High pressure will build in from the mid Mississippi Valley today, bringing cooler and drier air. A dry cold front on Friday reinforces cool and dry conditions heading into the weekend.
Broad upper troughing will be in place over the Ohio Valley. In the lower levels, dry NW flow is expected to persist. Friday - Friday Night We'll see a dry end to the work week with benign NW flow aloft and high pressure in control at the surface. Look for plenty of sunshine with highs in the low to mid 80s and Friday night lows in the 56 to 61 degree range.
Lingering stronger westerly winds and good boundary layer mixing will lead to breezy day, with probabilistic guidance and soundings indicating gusts 30-35 mph, with higher gusts across northern areas who are further entrenched in the cooler airmass. And yes, realize current gusts (30-40 kts) are even higher at press time, but the low level cold advection is being exhausted. Tight baroclinic zone over the northern Great Lakes will be settling south tonight-Friday, with limited moisture/weak low level convergence cold front tracking south of the Michigan during the day. There is some semblance of 850-700 MB Theta-E ridge working through Friday morning, with PV values > 0.
Upper troughing has moved over the great lakes this morning and the upper ridge over the rockies begins to shift to the northern plains. Could see some afternoon diurnal cumulus development today but otherwise the lower levels should remain dry. A bit warmer temperatures can be expect as the ridge shifts towards us with highs today sitting near 80 through the CWA. A very slowly progressive mid-level ridge is expected across the region for the weekend. Despite the ridge aloft, there are a couple chances for some pcpn.
This high is maintaining very light north flow across the Southern Plains. The air mass to the west of the cold front is characterized by dewpoints in the 40s and 50s.
High pressure ridge over the region will allow temperatures to continue to climb through Thursday.
Dry and Warmer. With high pressure dominating the region, dry conditions and a warming trend will continue today and tonight. Highs today will be warmer than yesterday and several degrees warmer than those more typical of early June.
Temps wl rmn slightly below normal today, then return closer to seasonal lvls on Fri as upper ridging begins to strengthen ovr the Mid-South.
236 AM CDT Thu Jun 11 2020 An upper level ridge will build over the southern plains through the weekend and into the following week.
We will be under cyclonic flow aloft in the base of a trough tonight and Thursday.
Temperatures are mostly in the upper 60s to mid 70s for the lower elevations. broad upper level ridging will continue to move across Colorado through Thursday. Given the upper level ridging moving overhead, dry conditions will prevail through tomorrow afternoon. A few areas over the San Luis Valley will drop into the mid 30s, with a few locations possibly seeing near freezing conditions. Mozley No big changes in current forecast with upper level ridging building across the Rockies through the day Friday. The generally weak southerly flow aloft combined with weak upslope flow across the plains will allow for slowly increasing available moisture to support isolated to scattered afternoon and evening showers and storms, with the best coverage expected over and near the higher terrain Friday afternoon and evening.
930 PM PDT Wed Jun 10 2020 High pressure aloft will weaken Thursday, but still bring another very warm day tomorrow.
SHORT TERM (Now through Friday): High pressure continues to build across Texas as another cold front surges south of Canada across the northern CONUS into Friday. Temperatures will likely top off a degree or two cooler than yesterday for the mid to lower RGV, with very comfortable conditions, despite highs in the 90s, as RH values dip below 40 percent for most locations. Temperatures overnight bottom out into the 60s under mostly clear skies, and another comfortable but warm day is expected on Friday with highs in the low 90s and RH values near 40 percent.
Dry and mostly clear conditions through the short term across South- Central Texas on the eastern side of the upper level ridge.
531 AM MDT Thu Jun 11 2020 500mb RAP analysis and satellite imagery showed a trough over the eastern CONUS with a ridge building to its west, placing the region under northwest flow. As the upper ridge progresses from the Great Basin to the eastern Rockies today and Friday, dry weather, sunny skies, and a warming trend are expected. High temperatures climb from the 80s today to mainly the low 90s on Friday.
750 AM EDT Thu Jun 11 2020 A cold front will finish passing through the area by midday. Another front will drop through on Friday, with perhaps an isolated shower, but its main impact on our weather will be cooler temperatures to start off the weekend. Actual surface cold front will dip through with shallow moisture during midday, with perhaps isolated showers. Weak surface ridging will allow for a period of mainly dry weather for Friday, as temperatures starting in the 50s peak in the 70s to lower 80s. Temperatures drop a few degrees cooler Friday night than on the previous night, with lows in the upper 40s to lower 50s.
Dry, pleasant wx is expected w/ high pressure in control. Expect mostly clear skies and highs in the low 90s & lows in the 60s.
/JNE/ Today and Tonight: High pressure will be in control of the weather today over the region which will result in clear skies and most of all rain free weather! A dry air mass has filtered into the ArkLaMiss as well post a cold front that swept across the state on yesterday. So even though the high pressure will rule over much of the southeast, high temperatures will struggle to get past the mid 80s due to the drier air. Otherwise, pleasant conditions will prevail today! Temperatures tonight will be in the low 60s under clear skies.
/Issued 211 AM CDT Thu Jun 11 2020/ An upper level high was located over southwest Texas, an upper level low was moving northeast into eastern Canada from the Great Lakes, and an upper level trough was approaching the Pacific Northwest coast. The upper flow will be zonal across the Panhandles this morning before becoming more northwest by late this afternoon as the upper level high expands somewhat over New Mexico. Mid level moisture and a couple of mid level short wave trough will rotate around the high to our south and move across the northern CWA this afternoon and tonight. Showers and thunderstorms will be possible again Friday afternoon and evening across the Oklahoma Panhandle and the northern Texas Panhandle as another short wave trough rotates the area on the north side of the high.
Tempo MVFR CIG in at TRI this morning, but otherwise VFR conditions are forecast through the period at all sites as drier air moves in behind a cold front. Still leaving fog out of forecast for tomorrow morning as the low-levels look too dry.

While upper level support looks rather weak given weak flow and rising heights, there could be enough focus along this trough/boundary to support some isolated shower and thunderstorm development. However, this low and increasing WAA is forecast to lift northeast and could see some isolated development across the east and southeast portions of Baca county during the evening hours. Next upper trough moves into the western U. on Friday pushing the ridge axis eastward and allowing for a southerly tap of moisture to enter CO.
Temperatures today will peak as high pressure ridge builds into the Four Corners region.
349 AM MDT Thu Jun 11 2020 500mb RAP analysis and satellite imagery showed a trough over the eastern CONUS with a ridge building to its west, placing the region under northwest flow. As the upper ridge progresses from the Great Basin to the eastern Rockies today and Friday, dry weather, sunny skies, and a warming trend are expected. High temperatures climb from the 80s today to mainly the low 90s on Friday.
/issued 258 AM CDT Thu Jun 11 2020/ SHORT TERM (Now through Friday): High pressure continues to build across Texas as another cold front surges south of Canada across the northern CONUS into Friday. Temperatures will likely top off a degree or two cooler than yesterday for the mid to lower RGV, with very comfortable conditions, despite highs in the 90s, as RH values dip below 40 percent for most locations. Temperatures overnight bottom out into the 60s under mostly clear skies, and another comfortable but warm day is expected on Friday with highs in the low 90s and RH values near 40 percent.
434 AM MDT Thu Jun 11 2020 The warming trend will continue across the region today as a ridge of high pressure builds over the Rockies in response to a deepening mid-level trough over the eastern Pacific. Advection of warmer air in southwest flow with sunny to mostly sunny conditions will help temperatures recover to near normal levels this afternoon. On Friday, the eastern Pacific trough develops a clear split as it moves to the West Coast. Concurrently, flow becomes more southerly as the ridge axis is driven eastward over the High Plains.
410 AM CDT Thu Jun 11 2020 High pressure will be in control of the weather today over the region which will result in clear skies and most of all rain free weather! A dry air mass has filtered into the ArkLaMiss as well post a cold front that swept across the state on yesterday. So even though the high pressure will rule over much of the southeast, high temperatures will struggle to get past the mid 80s due to the drier air. Otherwise, pleasant conditions will prevail today! Temperatures tonight will be in the low 60s under clear skies.
Cold front has pushed well into Georgia this morning resulting in cooler and drier air being ushered in from the northwest. Temperatures this morning are about 10 to 15 degrees lower than they were yesterday at this time, sitting in the low to mid 60s. Plenty of sunshine is expected today with afternoon highs topping out in the lower 80s, but more importantly dewpts in the upper 50s will make it feel amazing outside.
/issued 143 AM CDT Thu Jun 11 2020/ An upper level ridge of high pressure will be the main weather influence across west Texas and southeast New Mexico the next seven days. An upper level disturbance rotating around the periphery of the ridge combined with upslope flow will spark isolated to scattered thunderstorms across portions of the southeast New Mexico Plains and the Guadalupe, Delaware and Davis Mountains.
Today through Friday After a chilly morning west of the Divide, a relatively pleasant day is in store for the area as a ridge builds and advects warmer and drier air from the southwest. By Friday the ridge axis will be to the east and temperatures will increase further; 700mb temperatures should be in the +14C to +16C range.
324 AM MDT Thu Jun 11 2020 Upper ridge is building across the central to northern Rockies, with surface ridging extending from southern Plains high pressure. Upper ridging will remain in control through Friday as the main axis crosses the northern Plains.
A strong upper level ridge centered over the Southern Plains and northern Mexico expanded and shifted northwestward into the Desert Southwest yesterday. The increase in heights from the ridge will lead to further warming today as high temperatures top out between 107-109 across the bulk of the lower deserts. A Pacific trough will also approach the West Coast today, eventually digging across central California on Friday. The trough will bring increased height packing through Friday leading to increasing winds.
542 AM EDT Thu Jun 11 2020 Dry weather and seasonable temperatures are expected through the rest of the work week under building high pressure. A cold front should complete its passage early this morning, with just a band of clouds associated along and behind it.
This will continue through today and tonight as weak dry high pressure builds south of the region toward the Southern Plains.
/Issued 236 AM CDT Thu Jun 11 2020/ An upper level ridge will build over the southern plains through the weekend and into the following week.
Vertz Ridge of high pressure will build over the area today bringing mostly sunny and generally dry conditions. There is a disturbance that moves into western zones this afternoon/evening that may produce an isolated thunderstorm or two, but as this activity tries to move off the mountains, the ridging and dry downslope winds should quickly dissipate them. Ridge amplifies over the area on Friday as trof deepens along the west coast. With the downslope winds and increasing subsidence under the building ridge, temperatures push into the 90s for highs Friday afternoon. Each trough/upper low was associated with uncertainties in the models.
748 AM EDT Thu Jun 11 2020 Dry weather and seasonable temperatures are expected through the rest of the work week under building high pressure. Dry conditions and more comfortable conditions expected today with building high pressure.
410 AM CDT Thu Jun 11 2020 Today and Tonight: High pressure will be in control of the weather today over the region which will result in clear skies and most of all rain free weather! A dry air mass has filtered into the ArkLaMiss as well post a cold front that swept across the state on yesterday. So even though the high pressure will rule over much of the southeast, high temperatures will struggle to get past the mid 80s due to the drier air. Otherwise, pleasant conditions will prevail today! Temperatures tonight will be in the low 60s under clear skies.
519 AM MDT Thu Jun 11 2020 The warming trend will continue across the region today as a ridge of high pressure builds over the Rockies in response to a deepening mid-level trough over the eastern Pacific. Advection of warmer air in southwest flow with sunny to mostly sunny conditions will help temperatures recover to near normal levels this afternoon. On Friday, the eastern Pacific trough develops a clear split as it moves to the West Coast. Concurrently, flow becomes more southerly as the ridge axis is driven eastward over the High Plains.
333 AM MDT Thu Jun 11 2020 Ridge of high pressure will build over the area today bringing mostly sunny and generally dry conditions. There is a disturbance that moves into western zones this afternoon/evening that may produce an isolated thunderstorm or two, but as this activity tries to move off the mountains, the ridging and dry downslope winds should quickly dissipate them. Ridge amplifies over the area on Friday as trof deepens along the west coast. With the downslope winds and increasing subsidence under the building ridge, temperatures push into the 90s for highs Friday afternoon.

310 AM MDT Thu Jun 11 2020 Upper ridging will continue to amplify over the west-central U.
426 AM CDT Thu Jun 11 2020 Latest surface analysis showed a cold front from Lake Huron to northern Georgia to Florida Panhandle to northern Gulf. Surface dewpoint values ranged from the lower 60s across southwest Mississippi to near 70F around the Mississippi Delta. Upper air analysis showed a trough axis from Lake Superior to Tennessee Valley, creating a northwest flow over the Plains and west flow over mid Mississippi Valley. A broad ridge was located over west Texas creating a light northwest flow over the Lower Mississippi Valley. Upper level trough will shift east and allow the ridge over Texas to build over the Plains through Friday. Several disturbances will dive south on the back side of existing trough from Lake Superior to the Tennessee Valley over the weekend.
CAMs continue to point to convective initiation around the noon hour along the cold front that is posed to push southwest out of Ontario and Manitoba today. Primary concern today will be convective development this afternoon along a back door cold front. The cold front will push southwest from Manitoba during the afternoon with temps rising into the mid 70s and some moisture pooling along and ahead of the front allowing MUCAPE to climb into the 1000 to 1500j/kg range. Storm speed and PWATs less than an inch will limit the areal coverage of heavy rainfall with the highest amounts in narrow tracks possibly seeing a half inch or so. A deep long wave trof over the Great lakes will shift a bit eastward as H5 ridging starts to build into the Dakotas.
318 AM MDT Thu Jun 11 2020 An upper ridge will build up from the south, increasing heights and therefore temperatures for today for readings just about average for this time of year. Readings should be about 5 to 8 degrees warmer over yesterday's readings with low to mid 80s for the plains and upper 50s to low 70s for the mountains and high valleys. Clear skies are expected overnight with warming overnight lows due to the warm advection under the building ridge. For Friday, the upper level ridge axis will center itself across Colorado. Nearly full sunshine and warmer air aloft will push highs back to 90F or greater across the plains. There is just enough mid level moisture under the ridge for isolated storms to develop by mid afternoon over the Front Range mountains and Park County.
1048 AM EDT Thu Jun 11 2020 Seasonably cooler, less humid and rain-free conditions are expected through late week and into the weekend.
