155 AM EDT Sun Apr 14 2024 A ridge of high pressure will move east overnight as a warm front lifts northeast into the region. Low pressure tracking across the Great Lakes on Sunday will bring a threat for showers and thunderstorms Sunday late afternoon into Sunday night.
250 AM CDT Sun Apr 14 2024 - Highs will reach the lower 80s today and tomorrow, with lows only in the 50s to lower 60s.
1220 AM EDT Sun Apr 14 2024 A cold front moves across the region tonight. Low pressure tracks through the area Sunday night.
(Today) Clear skies and light winds have allowed temperatures to cool off into the low 50s early this morning. Despite lingering high clouds throughout the day, temperatures should heat up quickly with afternoon high peaking in the low 80s.
(Today and tonight) Upper ridging will dominate the region today and will help to warm highs into the mid 80s/mid 90s. Surface lee troughing will help to keep surface winds out southwest, but the gradient will be relaxed enough that winds should generally stay near or below 15 mph today. Upper flow will become more southwesterly tonight as the axis of the upper ridge pushes to our east and an upper low begins moving over Nevada towards the Four Corners. Winds will remain mostly out of the southwest overnight and will keep overnight lows in the low 50s to mid 60s.
407 AM EDT Sun Apr 14 2024 High pressure and upper ridging will build over the southeastern states during the first part of the week resulting in warm and dry conditions. The ridge will weaken mid-week as a pair of cold fronts approach the area bringing the potential for showers and thunderstorms. Temperatures will continue to warm, with highs in the low to middle 80s on tap for this afternoon.
Temperatures will struggle to warm into the upper 50s near the coast to low/mid 60s inland on Sunday (40s in the highest peaks).
1132 PM CDT Sat Apr 13 2024 Temperatures are running nearly 10 to 15 degrees warmer than last night, thanks to moderate return flow.
Upstream low pressure system has reached the Upper Mississippi Valley early this morning. Instability axis poking into Wisconsin just ahead of the low center continues to produce an area of convection over NE Wisconsin and much of Northern Michigan. and should largely end by around 12Z as the low center quickly tracks thru and out of Lower Michigan early this morning. High temps this afternoon will range from the 50s across Eastern Upper and far Northern Lower Michigan to the lower 70s near Saginaw Bay.
408 AM EDT Sun Apr 14 2024 A fast-moving area of low pressure will move over Central New York and Northeastern Pennsylvania Sunday.
142 AM PDT Sun Apr 14 2024 A much cooler day is in store as locally breezy northwest winds, clouds and scattered showers linger.
A weather system moving through the region will produce breezy to windy conditions through Sunday along with cooler temperatures and some light shower activity.
Upper level trough continues to spin off the CA coast with favorable conditions for thunderstorm development over central OR this evening.
(Today and tonight) With a broad area of 1 to 3 deg C warming of ~850 temps through this afternoon, highs today will be several degrees warmer than those seen yesterday over most areas outside of northwest Oklahoma, where similar highs are expected.
A weather system over the central California coast early this morning will move east across the area today bringing breezy to windy conditions, cooler temperatures, and light shower activity.
Discussion: In the upper levels, a trough will be over the East Coast and a ridge will be over the Great Plains. At the surface, high pressure will be over the Southeast. A weak cold front will move through the Ohio Valley tonight bringing rain to Kentucky and West Virginia. Gusts up to 30 mph are likely, maybe slightly higher in the higher elevations. With good mixing conditions, relative humidity values will likely be in the lower 30 percent range in most locations.
Temperatures across the Keys are in the lower 70s with dew points in the lower 60s.
213 AM EDT Sun Apr 14 2024 High pressure will build over the southeastern states through early in the week with resulting dry and warm conditions. The ridge will weaken midweek as a couple of cold fronts approach the area.
653 AM EDT Sun Apr 14 2024 A fast-moving area of low pressure will move over Central New York and Northeastern Pennsylvania Sunday.
712 AM EDT Sun Apr 14 2024 The upper-level pattern is flattening out as ridging builds in from the west. PW values continue to hover in the lowest 10th percentile and near record lows with this pattern in play. The ridge will continue to flatten before starting to amplify over the region again as trough axis propagates east.
707 AM CDT Sun Apr 14 2024 - Highs will reach the lower 80s today and tomorrow, with lows only in the 50s to lower 60s.
546 AM CDT Sun Apr 14 2024 (Today) Clear skies and light winds have allowed temperatures to cool off into the low 50s early this morning. Despite lingering high clouds throughout the day, temperatures should heat up quickly with afternoon high peaking in the low 80s.
A strong low pressure system will bring gusty winds and cooler temperatures for today with isolated showers on Monday. Low pressure spinning just of the central California coast early this morning, will start to push to the east over the next day. The low tracks inland this evening, digging slightly southward as it moves eastward. Additionally, cooler air will continue to move into the region. The low will cross the area on Monday. CAMs and ensemble guidance has trended drier over the past several runs, giving higher confidence that most areas will remain dry as the trough moves through our region.
A low pressure system is still on track to move into the British Columbia area on Monday causing the pressure gradient to tighten over the Northern Rockies.
(Today through Monday) A 500 mb ridge positioned over the Great Plains will translate eastward towards the Southeast CONUS over the course of the short term period. Georgia will remain underneath northwesterly upper level flow ahead of the ridge. After the morning begins with temperatures in the upper 40s to low 50s, the warming trend will continue as 1000-500 mb heights continue to rise under the high and ahead of the ridge. High temperatures on this afternoon are forecast be mainly 6-10 degrees above daily averages, rising into the low to mid 80s.
After the brief cool down, high pressure will push temperatures back to well above average later in the week. Breezy to windy gradient winds under the low, but otherwise dry this far south with precip chances remaining north of our area.
We should remain mostly dry today and Monday with high temperatures in the lower 80s.
340 AM PDT Sun Apr 14 2024 A trough of low pressure will bring cool, breezy weather and scattered showers over Orange, San Bernardino and Riverside Counties this afternoon and evening, and a chance for showers in San Diego County.
654 AM CDT Sun Apr 14 2024 We should remain mostly dry today and Monday with high temperatures in the lower 80s.
(Today and tonight) Shower activity continues as the low slowly moves inland this morning. Expect showers to lighten through the late morning as the low becomes less organized while moving inland.
in the vicinity of a closed upper level low. The cold upper level low pressure over northern California will move into Nevada today.
936 AM EDT Sun Apr 14 2024 A fast-moving area of low pressure will move over Central New York and Northeastern Pennsylvania Sunday.
The Upper low is currently spinning just offshore of the SF Bay and will shift inland over central California by this afternoon. The upper low shifts east on Monday with dry weather returning though clouds may linger for some areas and temperatures will still be 5 to 10 degrees below normal. An East Pacific ridge of high pressure will build inland and provide dry weather through the week along with warming temperatures.
Overnight lows are expected to only drop into the low to mid 60s tonight, mainly due to the constant influx of warm southerly winds, and some lingering cloud cover early this morning and again later tonight.
These showers will persist through the day as low pressure moves inland over Nevada. High pressure will build back in through this week keeping things generally dry and warmer.
604 AM CDT Sun Apr 14 2024 - Highs will reach the lower 80s today and tomorrow, with lows only in the 50s to lower 60s.
Weak high pressure overhead on Sunday before upper- level troughing returns on Monday. With it cooler temps and showers are slated to return. However, more ridging is likely later in the upcoming week with the potential for more warm and dry weather.
Weak ridging aloft will allow for fair skies throughout much of the day with the exception of morning stratocu that should dissipate with the onset of daytime heating. Regarding high temperatures today, NBM has been trending a little cooler than recent observed afternoon temps.
The cool Gulf waters will keep the highs along the coast in the 75 to 80 degree range.
618 AM CDT Sun Apr 14 2024 (Today through Monday) Deep South Texas and the Rio Grande Valley will remain on the northern periphery of 500 mb high pressure centered over the Bay of Campeche during the period. Meanwhile, at the surface, an enhanced pressure gradient will exist courtesy of high pressure over the Gulf of Mexico interacting with low pressure over Mexico.
This will allow for slightly above average temperatures in the low-to-mid 90s for the Rio Grande Plains and the Brush Country today and tomorrow, with the Coastal Bend and Victoria Crossroads regions reaching near normal temperatures in the upper 70s to low 80s.
A warming trend will begin Monday with dry and warmer weather expected through the end of the week. An upper low over Central California continues to send bands of showers and isolated thunderstorms into the Central Coast early this morning, while areas south of Santa Barbara have been relatively quiet. Models have been consistent showing a second upper low, currently just west of the Bay Area, rotating through the area by this afternoon. Dry and warmer weather expected Monday with some locally breezy north winds.
Gusty SW winds are expected to develop this afternoon as the morning inversion lifts and 25-35 kt winds at the top of the boundary layer mix down to the surface, reaching mainly between 20-30 mph in the Valley, possibly 35-40 mph at times in some of the higher elevations. Discussion: In the upper levels, a trough will be over the East Coast and a ridge will be over the Great Plains. At the surface, high pressure will be over the Southeast. A weak cold front will move through the Ohio Valley tonight bringing rain to Kentucky and West Virginia. Gusts up to 30 mph are likely, maybe slightly higher in the higher elevations. With good mixing conditions, relative humidity values will likely be in the lower 30 percent range in most locations.
543 AM CDT Sun Apr 14 2024 (Today through Monday) Early this Sunday morning, temperatures were much warmer than yesterday at this time thanks to south breezes. As southwest winds become increasingly gusty up to 30 mph, high temps will reach the lower to mid 80s for most locations. The upper level ridge overhead will be flattened slightly by a system moving across the Ohio Valley.
CIMSS satellite-derived vorticity analysis places a mid- and upper-level ridge centered in the western Gulf of Mexico. Closer to home and near the surface, high pressure remains centered over the Florida Peninsula, with associated anticyclonic flow advecting scattered cumulus cloud cover across the Florida Keys in the mean low-level northeast to east flow. High pressure over the Florida Peninsula will slide into the western Atlantic, and remain in place through the middle of the week. Thereafter, a secondary high pressure moving in from the Central Plains will gradually blanket the Gulf of Mexico.
Through Mon, this ridge will weaken, flatten, and slowly nudge EWD toward the Atlantic as a low pressure over WI quickly scoots across the Great Lakes, New England and into the N Atlantic dragging an associated front SEWD pinching the ridge over the SE US. In the upper levels, somewhat flat ridging is present across the midsection of the US. The ridge will become more amplified on Mon, as a low digs in the SW US with flow becoming NW into C AL. Our low level flow will start today as SW around the ridge but become more SRLY by Mon afternoon as the ridge center shifts. This will result in warmer daytime temperatures by a degree or so each day but more noticable with milder lows and dew points rising a tad.
605 AM CDT Sun Apr 14 2024 (Today and tonight) Upper ridging will dominate the region today and will help to warm highs into the mid 80s/mid 90s. Surface lee troughing will help to keep surface winds out southwest, but the gradient will be relaxed enough that winds should generally stay near or below 15 mph today. Upper flow will become more southwesterly tonight as the axis of the upper ridge pushes to our east and an upper low begins moving over Nevada towards the Four Corners. Winds will remain mostly out of the southwest overnight and will keep overnight lows in the low 50s to mid 60s.
An upper low will bring valley rain and mountain snow to much of northern and central Utah late today through Monday, along with much cooler temperatures across the region.
Otherwise, another fantastic day ahead with highs generally reaching the mid 80s this afternoon, though coastal areas will be a touch cooler as the afternoon sea breeze moves inland. The upper-level pattern is flattening out as ridging builds in from the west. PW values continue to hover in the lowest 10th percentile and near record lows with this pattern in play. The ridge will continue to flatten before starting to amplify over the region again as trough axis propagates east.
437 AM CDT Sun Apr 14 2024 (Today and tonight) With a broad area of 1 to 3 deg C warming of ~850 temps through this afternoon, highs today will be several degrees warmer than those seen yesterday over most areas outside of northwest Oklahoma, where similar highs are expected.
623 AM CDT Sun Apr 14 2024 (Today) Another unseasonably warm day is on tap across eastern Oklahoma and western Arkansas Today as a mid-level ridge builds over the area.
Some models show potential for higher based showers and maybe an isolated storm, so will maintain the low PoPs given to me from the model consensus (NBM). Still expecting storms to develop along the dryline during the afternoon on the back edge of the high cloud shield, with CAMs and global models favoring the TX South Plains region.
(Tonight through Monday night) A low amplitude upper level ridge continues to move across TX this afternoon. A strong high pressure cell over the Gulf is generating breezy southeasterly winds across South Central Texas. The upper ridge will continue its slow trek to the east tonight and Monday. The low level flow will continue from the southeast. Low temperatures will be a couple of degrees warmer than they were this morning. The low level flow will remain from the southeast Monday. High temperatures Monday will be about the same as today ranging from the lower 80s to middle 90s. Monday evening an upper level low will move into the Great Basin bringing a trough into west TX. This will push a dryline and cold front toward our northwestern area.
(Rest of today through Monday) South Florida currently sits between a mid level trough offshore in the western Atlantic and a building mid level ridge over the Gulf of Mexico. At the surface, a large area of high pressure will continue to gradually shift eastward into the Atlantic. Some moisture advection will continue to take place in the lower levels along the easterly wind flow which will allow for a just a slight uptick in humidity levels compared to the past several days. Highs on Monday will rise into the lower 80s across the east coast metro areas and into the mid to upper 80s across Southwest Florida.
344 PM EDT Sun Apr 14 2024 Low pressure and a cold front will move through the region tonight bringing a round of showers and some thunderstorms.
1226 PM CDT Sun Apr 14 2024 (Today through Monday) Deep South Texas and the Rio Grande Valley will remain on the northern periphery of 500 mb high pressure centered over the Bay of Campeche during the period. Meanwhile, at the surface, an enhanced pressure gradient will exist courtesy of high pressure over the Gulf of Mexico interacting with low pressure over Mexico.
1220 PM CDT Sun Apr 14 2024 (Today through Monday) Early this Sunday morning, temperatures were much warmer than yesterday at this time thanks to south breezes. As southwest winds become increasingly gusty up to 30 mph, high temps will reach the lower to mid 80s for most locations. The upper level ridge overhead will be flattened slightly by a system moving across the Ohio Valley.
However, the cigs may be persistent a bit longer this afternoon over E TX/SE OK/adjacent SW AR/portions of NW LA where low level theta-e ridging will persist, as well as shallow orographic lifting in the higher terrain of the Ouachitas of SE OK/Wrn AR.
152 PM EDT Sun Apr 14 2024 A cold front will move across the region late this afternoon into the evening.
Low pressure will move east across southern Nevada this afternoon and evening, bringing breezy to windy conditions, cooler temperatures, light showers and possibly a thunderstorm or two. The system will move east of the area Monday, with dry and breezy conditions and warmer temperatures.
A weak disturbance associated with the low pressure system over the Great Basin has moved into central Idaho and southwest Montana this afternoon. A weak cold front is still expected to move into the Northern Rockies on Monday as a low pressure system slides southward into British Columbia.
325 PM EDT Sun Apr 14 2024 High pressure will persist much of this week. A cold front might impact our area late in the week. This evening and tonight: Bermuda high pressure will extend near and just south of the region into the Gulf of Mexico, while a subtle lee side trough prevails. In the mid and upper levels of the atmosphere we lie within the northeast periphery of low amplitude ridging, and a continued very dry west-northwest flow. It's possible that if skies clear out quickly enough across far interior Georgia, that those places could be even cooler since winds will be calm there much of the night.
Upper low will be moving into Colorado Sunday afternoon, with strong southwest flow across West Central Texas. Mild tonight with lows in the mid 60s, and slightly cooler Monday night with lows ranging from the mid 50s to mid 60s (cooler in western zones).
1226 PM CDT Sun Apr 14 2024 - Highs will reach the lower 80s today and tomorrow, with lows only in the 50s to lower 60s.
349 PM EDT Sun Apr 14 2024 Offshore high pressure brings unseasonably warm and quiet weather through at least midweek. A bit of a summer-like surface pattern in place with high pressure offshore. Meanwhile in the mid levels the highest heights will be over the western Gulf leading to a WNW flow locally. Quiet forecast period here, with offshore high pressure maintaining an influence on the area.
A strong low pressure system will bring gusty winds and cooler temperatures for today with isolated showers on Monday. A large area of low pressure is over California and Nevada this morning. The low has two distinct centers. This has continued to increase the winds over northern Arizona and brought cooler air over the area. Low pressure spinning just of the central California coast early this morning, will start to push to the east over the next day. The low tracks inland this evening, digging slightly southward as it moves eastward. Additionally, cooler air will continue to move into the region. The low will cross the area on Monday. CAMs and ensemble guidance has trended drier over the past several runs, giving higher confidence that most areas will remain dry as the trough moves through our region.
the higher terrain locations of Southern Le Flore county have kept the cloud cover from expanding northward. the low level cloud cover is expected to become more scattered and from west to east. underneath the northeastern portion of the low level thermal ridge. have added adjustments to temps and sky cover based on the movement/development of the low clouds.
Expect high temperatures in the low to mid 80s inland to upper 70s along the coast.
Continued warm and dry weather is anticipated into tomorrow thanks to a building upper ridge from the Gulf of Mexico northward to the Ohio Valley, along with a persistant southwest to westerly 30-35kt LLJ. Some scattered showers and thunderstorms are anticipated to develop across Kentucky on Monday afternoon along a southward sagging cold front, but all of this activity is expected to stay to our north.
1225 PM CDT Sun Apr 14 2024 (Today and tonight) Upper ridging will dominate the region today and will help to warm highs into the mid 80s/mid 90s. Surface lee troughing will help to keep surface winds out southwest, but the gradient will be relaxed enough that winds should generally stay near or below 15 mph today. Upper flow will become more southwesterly tonight as the axis of the upper ridge pushes to our east and an upper low begins moving over Nevada towards the Four Corners. Winds will remain mostly out of the southwest overnight and will keep overnight lows in the low 50s to mid 60s.
(Tonight through Monday night) The deterministic NWP model runs predict a progressive upper pattern, with a disturbance on the West Coast and N-S ridge over the central CONUS at the beginning of the period, and with the upper disturbance approaching the southern Plains by the end of the period.
222 PM EDT Sun Apr 14 2024 Low pressure will track to our north tonight, and eventually drag a cold front southward across the area Monday.
Meanwhile, a very strong mid- and upper-level ridge will remained planted in the Gulf of Mexico, acting to deflect any potential disturbances away from the Florida Keys. Winds will take quite a bit of time to clock around to the east to southeast this week, and thus temperatures will remain pretty steady, with highs generally in the lower 80s, and lows in the lower to mid 70s. High pressure over the Florida Peninsula will slide into the western Atlantic, and remain in place through the middle of the week. Thereafter, a secondary high pressure moving in from the Central Plains will gradually blanket the Gulf of Mexico.
1059 AM CDT Sun Apr 14 2024 - Highs will reach the lower 80s today and tomorrow, with lows only in the 50s to lower 60s.
Although this will lead to some moistening of the boundary layer, the northward return of tropical moisture will be impeded by the western extension of the Bermuda ridge (into the eastern Gulf) and dewpoints should only recover into the m50s.
Western CONUS upper trough will cross the Rockies early this week and support unsettled and much cooler conds as mean western CONUS troughing persists. Dry trough will shift NE during the day forcing TS by late afternoon. Secondary cold front will push into the region Wed, bringing another chance for rain/snow showers along with much cooler conds.
Outside of areas of higher elevations, most locations will achieve high temperatures in the low to mid 80s this afternoon. Tomorrow, similar conditions will persist with slightly warmer maximum daytime temperatures. Winds will remain out of the west/southwest but gusts will finally back off (a nice reprieve from the last several days where winds have been quite breezy) as the high pressure shifts off to the east.
