/NEW/ Update: A swath of light rain and attendant cloud cover is beginning to encroach on our southeast zones this morning on the far northern periphery of the western Gulf tropical low pressure system. This cloud cover will begin departing the area to the west tomorrow, and highs will rebound into the lower 90s accordingly as the mid-level weakness is replaced by a strengthening upper ridge. /Issued 218 AM CDT Wed Jun 19 2024/ /Thursday Night Onward/ A mid level ridge centered over the Ohio Valley will build southwest into North and Central Texas starting Thursday night, providing hot, humid, and rain-free conditions for the weekend. Unfortunately, it will only increase dewpoints and heat indices locally, while the ridge shuts off any convective attempts and shunts all precipitation to our south.
1100 AM EDT Wed Jun 19 2024 High pressure will remain over the Mid Atlantic and Carolinas through much of this week. An anomalously strong 598 dam anticyclone at 500 mb will remain centered over the northern Mid-Atlantic today. At the surface, ~1030 mb high pressure is centered over the western Atlantic to the SE of New England. The anomalous mid-level ridge will de-amplify a bit Thursday as the center of the anticyclone retrogrades over the southeast. As such, max temps will remain near 90 and heat indices will remain under criteria as dew points once again mix out into the lower 60s.
Additionally this system will likely enhance the low-level shear profile this afternoon, presenting a threat for some brief tornadoes.
630 AM CDT Wed Jun 19 2024 - Temperatures today will be warmer than yesterday.
626 AM CDT Wed Jun 19 2024 (Today through Thursday afternoon) Another breezy night and morning as the low level jet continues to push low level moisture across the area. These clouds will lift, but deeper moisture associated with Potential Tropical Cyclone One begins to move into the region as the system moves onshore later today. Mid level clouds move into the region and rain chances begin to increase, particularly across the higher elevations where terrain will aid in shower development. With the additional moisture and the thermal ridge pushing further west, temperatures end up 5-10 degrees cooler than yesterday with most places reaching the low to mid 90s. Expect breezy, near advisory criteria winds over the higher elevations of Brewster and Presidio tonight and into Thursday morning.
413 AM CDT Wed Jun 19 2024 - Temperatures today will be warmer than yesterday.
(Now through Thursday) Mostly dry conditions will continue the next two days as the upper ridge continues to build westward over the southeast. The only rain chances continue to remain right along the immediate coastline where moisture and influences of the outer moisture envelope of Potential Tropical Cyclone One over the southwestern Gulf are more noticeable. The one good thing will be temperatures as cloud cover and a rather stiff easterly wind will keep temperatures on the cooler side with highs in the upper 80s to low 90s.
503 AM CDT Wed Jun 19 2024 - Thunderstorms for much of the morning today and cooler temperatures through the afternoon. This line of rain is basically straddling slow moving cold front. Models have had a hard time picking up on the location of the front as all of them have the boundary much further north into Kansas and as such that is where they are putting the highest rainfall. 75 inches of additional rainfall with the highest POPs (60-70%) along the KS-OK border and lower POPs as you move north.
613 AM CDT Wed Jun 19 2024 Updated aviation portion for 12Z TAF issuance - Quite a bit cooler today than yesterday, along with a chance of showers and thunderstorms.
Strong high pressure north of Bermuda continues to ridge west- southwest over the southeast U. Interaction between this high pressure and a tropical wave northeast of the Bahamas and another area of low pressure in the southwest Gulf of Mexico is producing gusty easterly winds over Florida for the next couple of days.
636 AM CDT Wed Jun 19 2024 - High pressure will bring cool and dry conditions today and tonight.
Strong high pressure at the surface and aloft, centered east of the region, will both continue to build west into the region. Highs today will be a touch warmer as they range from the upper 80s to lower 90s. Anomalously strong 595 dam mid-level ridge will have expanded from its origins over the mid-atlantic states into much of the mid MS valley. The stout ridge will provide a rather dry airmass aloft limiting the potential for storm coverage as chances for isolated showers and storms will remain confined to the afternoon as peak heating occurs and mainly focused along our far southern counties. Ridging at the surface and aloft will help mitigate rain chances as the more moist tropical airmass will be in place further west southwest as the potential tropical disturbance continues its track west through Mexico.
618 AM EDT Wed Jun 19 2024 High pressure will remain over the Mid Atlantic and Carolinas through much of this week. Water vapor imagery this morning continues to highlight the anomalous mid-level ridge anchored over the eastern seaboard. Sfc dewpoints across central NC remain in the lower to mid 60s (the plume of higher dew points > 70 has largely been displaced well to our north and west). The anomalous mid-level ridge will de-amplify a bit Thursday as the center of the anticyclone retrogrades over the southeast. As such, max temps will remain near 90 and heat indices will remain under criteria as dew points once again mix out into the lower 60s.
537 AM CDT Wed Jun 19 2024 (Today through Thursday Night) To begin the period, high pressure.
Storms developed along the cold front late Tue afternoon/evening and with the help of outflow the storms and effective cold front currently stretches from the northern TX Panhandle, into southern KS and to north of Kansas City. By Thu morning, upper ridging will extend from the Mid Atlantic States into the Tennessee Valley. For Fri, upper ridging is expected to expand into the Ozark region and lower Mississippi Valley. However, confidence is low that we will see anything as widespread as we are seeing right now, as the front/trough that moves through will be very progressive. For the the start of the next work week, there is good agreement between the GFS and ECMWF in upper ridging building from the Desert Southwest through the Southern Plains and will allow anomalously warm 850mb temps to move-in from the southwest, bringing widespread highs around 100.
Temperatures near average through Thursday then warming to 10 to 15 degrees above average this weekend with widespread triple digit maximum temperatures across the lower elevations.
(Rest of Today) A large area of high pressure continues to be centered off the northeastern seaboard this morning. The western portion of this ridge extends west into the southeastern CONUS. One is an actual cold front that extends from Wisconsin into central Iowa and western Oklahoma. The strong area of high pressure is forecast in most models to build to the WSW today and towards the Tennessee Valley.
150 PM EDT Wed Jun 19 2024 High pressure will cover the region through the end of the week. A broad ridge covers the eastern seaboard and extends into the OH and TN Valleys. Additionally, diurnally-driven clouds had formed mainly in the mountains, closer to an area of convergence along the periphery of the ridging to the west, and also in response to afternoon heating. Tonight and tomorrow, the ridge is flattened to a more east-west orientation as short wave energy rides over its northern side.
Bowlan (Thursday through Wednesday) Upper level ridging will begin expanding back westward during the day Thursday which should lead to diminishing cloud cover over the region and the beginning of a warmup heading into the weekend.

The heaviest rainfall amounts tonight are expected further south with the higher PWAT values, although these should only range in the 0.
Surface wind observations suggest the zone of the greatest confluence was confined to the Lower and Middle Keys today. Satellite-derived vorticity analysis shows a well-defined tropical upper-tropospheric trough (TUTT) cell pinching off in the vicinity of the Florida Keys. Finally, at the surface, a strong area of high pressure east of New England continues to interact with newly formed Tropical Storm Alberto in the Bay of Campeche.
246 PM CDT Wed Jun 19 2024 - Cooler through Thursday with scattered showers/storms, but organized severe weather/heavy rain threats are unlikely.
137 PM EDT Wed Jun 19 2024 A warm day today but expecting dew points to be lower as upper ridge has strengthened over the area. The easterly flow around the upper ridge centered to the northeast across the mid Atlantic should keep skies a little sunnier in the northeast third of the forecast area than the central and southern sections. Temperatures were warmer in northeast TN at late morning mainly due to less cloud cover. Expect highs to be around 90 to the lower 90s most locations.
Tonight will be muggy and humid, given light SEly winds maintaining moisture flux with dewpoints in the 60s, along with standing water helping keep the lower boundary layer near saturation through sunrise Thursday. Strong midlevel high pressure ridging over the eastern U.
(Rest of today through Thursday) Building high pressure influences surface and aloft will provide dry conditions through Thursday afternoon.
149 PM PDT Wed Jun 19 2024 Building upper level ridge in the Southwest US will lead to a warming trend late week and into the weekend. High temperatures this weekend will be as much as 8 to 12 degrees average for the inland valleys onto the lower coastal mountain slopes as well as the deserts.
124 PM CDT Wed Jun 19 2024 (Rest of Today) A large area of high pressure continues to be centered off the northeastern seaboard this morning. The western portion of this ridge extends west into the southeastern CONUS. One is an actual cold front that extends from Wisconsin into central Iowa and western Oklahoma. The strong area of high pressure is forecast in most models to build to the WSW today and towards the Tennessee Valley.
1220 PM CDT Wed Jun 19 2024 (Rest of today through Thursday) Building high pressure influences surface and aloft will provide dry conditions through Thursday afternoon.
The area will remain between high pressure to the north and low pressure to the south. Lows tonight should be in the mid to upper 60s away from the warmer coastal areas with highs Thursday ranging from the lower to mid 80s near the coast to around 90 inland, both of which are near to slightly below normal.
Continued warming and drying through Thursday even with an upper trough still over the area, but the main reason for the warming is deeper than normal thermal low pressure at the surface.
Upper level troughing to the west and upper level ridging over the Great Plains has lead to a dry upper level air flow.
1240 PM CDT Wed Jun 19 2024 - High pressure will bring cool and dry conditions today and tonight.

Abnormally strong mid-level ridging remained centered over the Mid-Atlantic Region at midday, while an upper trough was identified by multispectral satellite imagery over the Bahamas and South Florida. High temperatures will range from the upper 80s far north and in the higher terrain east to the low 90s south, west and central. The anomalous upper ridge will become more elongated overnight, extending from off the Mid-Atlantic Coast southwest to over the Mid-South Region while the mid to upper low remains over the Bahamas and South Florida. Lows will range from the upper 60s east and far north to the lower 70s southwest and central.
247 PM EDT Wed Jun 19 2024 High pressure along with dry weather and near normal temperatures are expected through Thursday.
158 PM CDT Wed Jun 19 2024 - Temperatures today will be warmer than yesterday.

Otherwise, a warmer day is expected on Thursday with high temperatures in the mid 80s to mid 90s. /Issued 218 AM CDT Wed Jun 19 2024/ /Thursday Night Onward/ A mid level ridge centered over the Ohio Valley will build southwest into North and Central Texas starting Thursday night, providing hot, humid, and rain-free conditions for the weekend. Unfortunately, it will only increase dewpoints and heat indices locally, while the ridge shuts off any convective attempts and shunts all precipitation to our south.
(This evening through Thursday night) The forecast area remains positioned under a mid/upper level ridge axis sandwiched between a notable inverted easterly wave/tropical system over the western Gulf of Mexico and an area of broad cyclonic flow aloft over most of the western CONUS. As broad midlevel subsidence beneath the ridging aloft becomes more pronounced, the shallow cellular convection along and ahead of the outflow boundary earlier today is expected to quickly diminish with time through the rest of this afternoon. Tonight, inverted upper troughing associated with the Gulf tropical system will begin shifting westward while an impressive plume of deep layer moisture pivots over our region.
Trough pattern slowly degrades as a ridge builds late this week. (This evening through Thursday) Cooler temps today with ample sunshine across the area.
One last dry day is on tap as a trough continue's to hang over the western U. Thursday will see that trough receding to the north as high pressure builds in. Accompanying the high will be moisture provided by Tropical Storm Alberto that is currently impacting southern Texas.

Expect breezy, near advisory criteria winds over the higher elevations of Brewster and Presidio tonight and into Thursday morning.
Hot and dry conditions continue with strong ridging in place tonight and Thursday. Discussion: At mid afternoon today the forecast area remains under the influence of a large upper level ridge centered over New Jersey. Dew points are lower today, mostly lower to mid 60s with the dry air and subsidence under the ridge. Tonight cloudiness should thin out based on model guidance and drop to the lower to mid 60s, upper 60s south. Thursday is forecast to be slightly warmer with less high cloud cover and still lower dewpoints. Above average temperatures continue with strong ridging in place.
