535 AM EDT Tue Sep 19 2023 High pressure remains in control through the end of the work week providing dry weather and a slow warming trend, with river valley fog developing at night. A high pressure system will provide dry weather today and tonight.
Dry with above average temperatures before a trough brings gusty winds and a few degrees of cooling the second half of the week.
556 AM CDT Tue Sep 19 2023 (Today and tonight) The main concerns today will be a chance for severe storms, mainly north of a San Angelo to Brownwood line, and the warmer temperatures. First, although an upper level trough will move by the area during the morning hours, convective temperatures are expected to be easily reached this afternoon along the dryline which will sharpen up just to the west of our area. To the east of the dryline, dewpoints will be in the lower 60s.
927 AM EDT Tue Sep 19 2023 High pressure will build into the region today and persist through the end of the week. Surface features remain the same with high pressure settling into the Great Lakes. A low pressure system over the central plains region will track north northeastward in the near term towards the arrowhead of Minnesota.
633 AM EDT Tue Sep 19 2023 Building high pressure will provide dry conditions through the week, with potential for foggy river valleys each morning.
We will see quite the spread in temperatures today as well, with cooler temperatures in the north, due to remnant cloud cover. So, those in the north will stick in the mid-upper 70s, with those south of Interstate 80 seeing temperatures in the low-mid 80s. Temperatures will stay a little warmer due to cloud cover, with most in the low 60s.
(Today and tonight) The main concerns today will be a chance for severe storms, mainly north of a San Angelo to Brownwood line, and the warmer temperatures. First, although an upper level trough will move by the area during the morning hours, convective temperatures are expected to be easily reached this afternoon along the dryline which will sharpen up just to the west of our area. To the east of the dryline, dewpoints will be in the lower 60s.
621 AM EDT Tue Sep 19 2023 High pressure building in from the west persists through at least mid week with dry conditions and pleasant temperatures. A coastal low or coastal trough is forecast impact the area late in the week into the weekend. High pressure will continue build over the area from the north. Strong subsidence produced by the high will result in clear skies through tonight. Highs will be near normal in the lower 80s but with below normal humidity. High pressure will continue to produce clear skies and light winds tonight. Ridging will be the dominate feature through midweek leading to a calm, clear, and dry couple of days.
High pressure centered to our northeast over the Appalachians will still be the dominant features in the pattern today.
In the mid and upper levels this morning the Florida Keys remain at the southern extent of a trough that remains parked along the Eastern Seaboard. At the low and surface levels there is a quasi- stationary front that is just to our north.
639 AM CDT Tue Sep 19 2023 (Today through Wednesday Night) With a midlevel ridge continuing to build to our SW, conditions should remain near seasonable and generally benign in the immediate term. Afternoon highs should once again approach the low to mid 90s area-wide. A slightly warmer and more humid day is expected on Wednesday as the aforementioned ridge continues to strengthen to our SW.
Upstream showers positioned ahead of a lifting warm front decay before reaching any of the terminals this afternoon, but anticipate this being a source of moisture to sustain some diurnal high-based VFR FEW-SCT cloud. Cloud coverage increases tonight as the warm front approaches along with -SHRA to close out the TAF period. This initial round of activity slides by to the south today and early tonight, as lingering surface ridging within the background of ongoing subsidence in confluent flow maintains a dry and stable underlying profile. Renewed nocturnal low level jet development effectively invigorates forced ascent and moisture transport across the slowly advancing warm frontal zone over the lake Michigan corridor tonight.
636 AM EDT Tue Sep 19 2023 High pressure will build into the region today and persist through the end of the week. Surface features remain the same with high pressure settling into the Great Lakes. A low pressure system over the central plains region will track north northeastward in the near term towards the arrowhead of Minnesota.
Temperatures are forecast to warm back into the 80s across the eastern half of the county warning area as the low level thermal ridge slowly moves out. While temperatures out west will remain cooler as the front moves through bringing in a cooler air mass in it's wake. A broad trough is forecast to dig across the Western CONUS by the middle of the week placing North Dakota in southwesterly flow aloft. Models have the upper low cutting off over the Great Basin resulting in multiple disturbance moving through the Northern Plains. The upper low will move over the Northern Rockies by the end of the work week placing North Dakota in the left exit region of the jetstream resulting in large scale lift aloft.
For locations north of the Treasure Coast, dew points in the low to mid 60s provided a less humid start to the day.
Seasonably cool temperatures today in the upper 60s to low 70s warm into the low to mid 80s through the remainder of the week. West east arc of showers/storms within return low level theta-e ridge across IA will continue ewd near term yet expected to largely diminish with ern extent as they outrun sharp west-east instability gradient. Significant warmup this period as upper ridge expands sharply inbetween developing nrn plains cutoff and subtropical sys lifting up the east coast this weekend as larger scale east CONUS centered blocking unfolds.
(Now through Wednesday) Very pleasant weather conditions are expected to continue through much of the period as high pressure over the Appalachians maintains its hold across the local area. By Wednesday afternoon, the high will begin to move eastward into the Western Atlantic. Lows tonight will drop into the low to mid 60s north of I- 10 and the upper 60s to around 70 along the coast.
Ridging aloft is expected to strengthen today over the Great Lakes region with troughing occurring on the backside of this ridge.
743 AM EDT Tue Sep 19 2023 Building high pressure will provide dry conditions through the week, with potential for foggy river valleys each morning.
457 AM CDT Tue Sep 19 2023 (Today through Wednesday) High pressure will remain in control over the eastern CONUS through the short term period, with light winds gradually veering from northeasterly this morning to southeasterly by Wednesday. This will result in a mid-level cloud deck approaching from the west tomorrow afternoon but the low-levels will be too dry for any measurable precipitation. Low-level thicknesses today will be a little higher than yesterday but we will have a cooler start so will forecast highs near yesterday's values. Highs will be a couple degrees warmer tomorrow with the southeasterly winds.
917 AM EDT Tue Sep 19 2023 High pressure remains in control through the end of the work week providing dry weather and a slow warming trend, with river valley fog developing at night. Temperatures will feel comfortable this afternoon with highs in the mid-70s across the lowlands and the low 70s in the mountains. A high pressure system will provide dry weather today and tonight.
634 AM CDT Tue Sep 19 2023 (Today through Wednesday) Subtropical ridging extends from Mexico northward into much of AZ/NM/SW TX and not shift much in the short term periods. Upstream heights will fall out west Wednesday as an upper low drops south from Canada into the Pac NW. These lower heights will probably bring a slight boost in the low level pressure gradient over TX and perhaps slightly better onshore moisture.
(Rest of Today) Early morning fog has mostly dissipated in and around the river valleys, giving way to clear skies as high pressure remains dominant over the area. Today will be another lovely day as afternoon highs reach the lower 80s and mostly sunny skies persist aside from scattered afternoon cu.
239 PM EDT Tue Sep 19 2023 Dry high pressure will dominate our weather through the work week.
Wednesday looks to be slightly cooler than today, with afternoon highs in the upper 70s to middle 80s.
1219 PM EDT Tue Sep 19 2023 Low pressure will exit across the Maritimes today.
325 PM EDT Tue Sep 19 2023 High pressure gradually shifts offshore through midweek with dry conditions and pleasant temperatures. A coastal low or coastal trough is forecast impact the area late in the week into the weekend. Ridging aloft and at the surface persists tonight, with calm winds and efficient radiational cooling bringing cool temps and dry conditions. Strong ridging pattern continues Wednesday with dry conditions and only some scattered afternoon cu for cloud coverage. Ridging will be the dominate feature through midweek leading to a calm, clear, and dry couple of days.
Northwesterly to northerly flow aloft develops as a trough amplifies over the Southeast through the weekend and a ridge persists well of our west.
(This afternoon through Wednesday) High pressure is centered over the eastern CONUS and will continue to suppress rain chances while the airmass remains very dry. There will be a small warming trend today and tomorrow as the low-level portion of the ridge centered over the Mid-Atlantic region will allow for more of a southeasterly component in the 850mb flow, but afternoon dewpoints will continue to mix down into the 50s to near 60F which will result in comfortable humidity values during peak heating hours.
Breezy conditions will develop through this afternoon and early evening as an upper level trough begins to carve out over western Montana and north central Idaho. A big pattern change will begin tomorrow as the upper level trough further deepens and a cut-off low pressure circulation develops.
(This afternoon through Wednesday night) Over and around the Permian Basin, high pressure at the surface and aloft for the most part has kept development of convection at bay until recent. However, slightly more moisture returning could produce isolated showers and thunderstorms over the higher terrain of the Davis Mountains and northern Big Bend.
1230 PM CDT Tue Sep 19 2023 (Today through Wednesday Night) With a midlevel ridge continuing to build to our SW, conditions should remain near seasonable and generally benign in the immediate term. Afternoon highs should once again approach the low to mid 90s area-wide. A slightly warmer and more humid day is expected on Wednesday as the aforementioned ridge continues to strengthen to our SW.
211 PM MDT Tue Sep 19 2023 The pattern will become more active in the next several days due to the impact of the trough along the west coast. Today's convection from forcing ahead of the trough along with daytime heating has begun to bubble across far western and southwestern WY. Wednesday the low will still be along the PacNW coast, but the midlevel flow will be more off the Pacific, bringing more moisture into the region.
Early afternoon observations and model initialization fields indicate mid level moisture transport was strong enough to support new daytime elevated convection in southern WI back toward the surface warm front in IA/IL. The warm front is not well defined at the surface in Lower Mi by Wednesday morning within a weaker pressure gradient compared to upstream this afternoon. The mid level ridge builds overhead and becomes diffuse due to the central Plains circulation as it moves into the mid MS valley. Highs in the lower 70s are right on normal values for mid September.
310 PM EDT Tue Sep 19 2023 A ridge affects our region through the end of this week. Simultaneously, the core of this ridge moves from the Mid Ohio Valley to Atlantic waters near the Canadian Maritimes. Primarily fair weather is expected due to the prevalence of stabilizing subsidence and a relatively-dry low-level air mass accompanying the ridge.
Temps expected to reach into the low to mid 80s with some scattered, fair weather cumulus that can already be seen popping up on satellite. A fairly large high pressure ridge has settled in across the Mid atlantic and Southeastern states and will dominate the weather pattern for the next few days. This ridge will keep the area nearly cloud free through the short term with only some isolated mid level fair wx clouds developing this afternoon and again Wed afternoon.
This low will lift northward while the entire wave creeps east at a snails pace.
1253 PM CDT Tue Sep 19 2023 (Today and tonight) The main concerns today will be a chance for severe storms, mainly north of a San Angelo to Brownwood line, and the warmer temperatures. First, although an upper level trough will move by the area during the morning hours, convective temperatures are expected to be easily reached this afternoon along the dryline which will sharpen up just to the west of our area. To the east of the dryline, dewpoints will be in the lower 60s.
303 PM EDT Tue Sep 19 2023 Fair weather through the rest of the work week with high pressure in control. Winds will weaken this evening and skies will clear as high pressure builds in from the west.
113 PM EDT Tue Sep 19 2023 High pressure building in from the west persists through at least mid week with dry conditions and pleasant temperatures. A coastal low or coastal trough is forecast impact the area late in the week into the weekend. High pressure will continue to build over the area from the north. Strong subsidence produced by the high will result in clear skies through tonight. Highs will be near normal in the lower 80s but with below normal humidity. High pressure will continue to produce clear skies and light winds tonight. Ridging will be the dominate feature through midweek leading to a calm, clear, and dry couple of days.
A weak and mainly dry cold front crossed the area yesterday. A second stronger cold front now crossing Washington and central Oregon this morning will pass through our CWA this afternoon. Highs will be around 5 degrees cooler today, then an additional 5-10 degrees cooler on Wednesday as the upper level trough following the cold front settles in over the northern Intermountain Region. Scattered to broken mid-high level clouds associated with a cold front will cross the area today.
229 PM EDT Tue Sep 19 2023 High pressure will build over the region for the rest of the week. High pressure will build into the area tonight. High pressure over the area Wednesday will lead to a day of plenty of sunshine with only a small amount of diurnal cloud cover.
The 14Z CONSShort maxT output is very reflective of the highs advertised in the overnight forecast package, bringing the majority of the ArkLaTex to the low to mid 90s. Temperature maximums will still reach the lower 90s today under a more moist atmospheric column with PWATs above an inch. Otherwise, temperatures will fall toward milder minimums in the mid-to-upper 60s tonight before warming back up toward maximums in the lower 90s once again tomorrow. An upper-level high centered across north Mexico will remain firmly established through the period, positioned in such a way that the ArkLaTex will remain on the northern periphery of the ridge.
1142 AM CDT Tue Sep 19 2023 (Rest of Today) Early morning fog has mostly dissipated in and around the river valleys, giving way to clear skies as high pressure remains dominant over the area. Today will be another lovely day as afternoon highs reach the lower 80s and mostly sunny skies persist aside from scattered afternoon cu.
244 PM EDT Tue Sep 19 2023 High pressure remains in control through the end of the work week providing dry weather and a slow warming trend, with river valley fog developing at night. Dry weather will persist courtesy of high pressure over the mid- Atlantic. Temperatures tomorrow will be a few degrees warmer than today with highs reaching the upper 70s and low 80s in the lowlands.
An elevated warm front begins to lift northeastward into the area overnight, bringing lowering VFR ceilings between 06z and 12z. Additional scattered light showers will be possible through Wednesday morning as the surface warm front moves through, but predominant VFR conditions appear most likely. This initial round of activity slides by to the south today and early tonight, as lingering surface ridging within the background of ongoing subsidence in confluent flow maintains a dry and stable underlying profile. Renewed nocturnal low level jet development effectively invigorates forced ascent and moisture transport across the slowly advancing warm frontal zone over the lake Michigan corridor tonight.
1145 AM EDT Tue Sep 19 2023 High pressure remains in control through the end of the work week providing dry weather and a slow warming trend, with river valley fog developing at night. Dry weather will persist courtesy of high pressure over the mid- Atlantic. Temperatures tomorrow will be a few degrees warmer than today with highs reaching the upper 70s and low 80s in the lowlands. Key Point: * High pressure remains overhead, keeping conditions dry. High pressure at the surface and aloft will remain in place for the short term period keeping conditions dry and mostly clear Wednesday.
240 PM EDT Tue Sep 19 2023 High pressure will build over the East Coast through mid week. This high will then push northeast into New England while extending down through North Carolina late in the week. Low pressure expected to form off the Southeast coast may bring unsettled weather heading into the weekend. Isolated shallow fog banks over bodies of water remain possible late tonight, but should be few and far between given the low dewpoints in place. Expect lows in the 50s, although a few upper 40s remain possible in the typically cooler rural/low lying areas. Similarly, lows will have a warming trend as lowering low-level thicknesses are offset by increasing thick cirrus deck enveloping the southern Mid-Atlantic and light surface stirring Thus night, which will bottom out in the low/mid 50s (NW) to low 60s (SE).
The upper level pattern will consist of an upper level ridge building over the Plains with an upper level low digging into the Intermountain west. Towards the surface, a trough of low pressure will bisect the CWA throughout the short term period. As for temperatures, lows tonight look to range from the low 50s across west central Kansas to around 60 degrees across south central Kansas. Lows tomorrow night dip to the lower 60s to around 60 degrees.
116 PM EDT Tue Sep 19 2023 High pressure remains in control through the end of the work week providing dry weather and a slow warming trend, with river valley fog developing at night. Dry weather will persist courtesy of high pressure over the mid- Atlantic. Temperatures tomorrow will be a few degrees warmer than today with highs reaching the upper 70s and low 80s in the lowlands. Key Point: * High pressure remains overhead, keeping conditions dry. High pressure at the surface and aloft will remain in place for the short term period keeping conditions dry and mostly clear Wednesday.
335 PM EDT Tue Sep 19 2023 Fair weather through the rest of the work week with high pressure in control. Winds will weaken this evening and skies will clear as high pressure builds in from the west.
209 PM MDT Tue Sep 19 2023 Cooler air has filtered into the region over the past 24 hours, which has resulted in temperatures being 5 to as much as 20 degrees cooler than they were at this time yesterday. This cooler air will linger through the end of the week, and a weather system arriving Wednesday night will bring widespread soaking rainfall to the area, along with some higher elevation snowfall. Noticeably cooler air has worked its way into the area as high pressure builds in. Aside from the cooler air, skies are mostly clear, though there is some noticeable smoke from prescribed burns locally and even a few wildfires in the broader Northern Rockies region. Tomorrow will feature more of the same, with similar to slightly cooler temperatures across the region.
/21 (Now through Wednesday) Very pleasant weather conditions are expected to continue through much of the period as high pressure over the Appalachians maintains its hold across the local area. By Wednesday afternoon, the high will begin to move eastward into the Western Atlantic. Lows tonight will drop into the low to mid 60s north of I- 10 and the upper 60s to around 70 along the coast.
335 PM EDT Tue Sep 19 2023 High pressure will build over the region for the rest of the week. High pressure will build into the area tonight. High pressure over the area Wednesday will lead to a day of plenty of sunshine with only a small amount of diurnal cloud cover. A strong area of high pressure will reside across the eastern Great Lakes region through the period. A mid-level trough cutting across the Hudson Bay will be a key factor to what happens with the moisture from the low pressure system tracking along the Southeast coast. This is due 12Z GFS/ECMWF showing a drier forecast with the coastal low stalling along the Mid- Atlantic, and then getting swept out to sea by an advancing cold front.
146 PM EDT Tue Sep 19 2023 High pressure will build over the region for the rest of the week. High pressure arrives tonight, becoming centered across the eastern Great Lakes and Appalachians. Highs Wednesday will climb up into the mid to upper 60s across the higher terrain and the low to mid 70s across the lower elevations.
As the low level jet develops across the central plains this evening, expect convection to largely re-focus on eastern Oklahoma into southwestern Missouri.
A broad upper level trough will remain situated just to our north with the Keys lying on the southern periphery. Meanwhile, in the lower levels a ridge off the Carolina coast will promote a minor surge in easterly winds overnight. Meanwhile, the quasi-stationary boundary to our north will lift northeast starting tonight and interact with the upper level trough. This will spawn a broad area of low pressure off the FL/GA coast and causing our winds to turn northerly. The main question will be how much dry air infiltrates on the back side of the cyclone. Regardless of how and where this cyclone develops, it will quickly lift northeast. In its place, a large and expansive high pressure will move into the eastern half of the U.
Above normal temperatures and small rain chances will characterize the rest of the work week, with higher chances for rain arriving ahead of a low pressure system this weekend. This afternoon, central Illinois falls under a moderate southerly gradient between a ridge of high pressure centered over the mid Atlantic coast and an elongated area of low pressure over the Great Plains. Despite increasing cloud cover and the threat for scattered showers, temps will warm into the lower to mid 80s again Wednesday. Deubelbeiss A closed upper low is expected for form over the Pacific Northwest late in the week within a broader upper trough spanning the western CONUS into the Great Plains.
1123 AM EDT Tue Sep 19 2023 Low pressure will exit across the Maritimes today.
1105 AM EDT Tue Sep 19 2023 Building high pressure will provide dry conditions through the week, with potential for foggy river valleys each morning.
125 PM MDT Tue Sep 19 2023 Water vapor shows deepening upper trof over the western CONUS with lead short wave extending from SASK southward into the Central Rockies. At the surface, trof/cold front is shifting through the central/eastern Dakotas. Wide ranging early afternoon temps from the lower 70s in northeast WY. An additional few showers/storm possible later tonight across northwest SD within a bit better lift associated with short wave/trof. On Wednesday, main upper low reforms over the Pac NW, with increasing southwest flow through the Northern Plains.
137 PM EDT Tue Sep 19 2023 Building high pressure will provide dry conditions through the week, with potential for foggy river valleys each morning.
