Nil rain chances are advertised for this afternoon, with temperatures creeping up into the lower 80s at most communities, right around normal for this time of year. High pressure east of the Florida Peninsula will continue to slide into the west- central North Atlantic, then remain in place through the middle of the week. A secondary high pressure moving in from the Central Plains will gradually blanket the Gulf of Mexico, with slackened east to southeast breezes expected for the end of the week.
Brief high pressure will build into the area through Tuesday night.
Readings near to slightly below normal today will quickly rise into an above normal category by the middle of the week as strong high pressure builds into the area. An expansive closed low has progressed into the Great Basin early this morning as jet energy translating to the eastern side of the trough will pull vorticity and height falls across northern Arizona/southern Utah over the next 24 hours. With below normal heights only skirting the forecast area, slightly cooler than normal temperatures will prevail just one more day before succumbing to building high pressure ridging. Otherwise, modest midlevel height rises Tuesday on the trailing edge of the exiting trough axis will result in a 10F bump in temperatures.
959 AM CDT Mon Apr 15 2024 (Today through Tuesday) Early morning upper air pattern showed upper ridging from south Texas to the Dakotas, with an upper low centered near Las Vegas. At the surface, high pressure extended from near Bermuda westward across much of the northern Gulf of Mexico. The axis of the upper ridge will shift to the east of the area on Tuesday, as the upper low near Las Vegas lifts northeastward to near Omaha by Tuesday evening.
Radar rainfall estimates showed between 1 and 2 inches fell in that location in a matter of a few hours! Also to note, thunderstorms formed over the higher terrain west of Flathead Lake, then shifted over the lake just before midnight.
Gusty northerly winds expected through mid-week as high pressure builds into the CA coast. An inverted ridge of high pressure will continue to build into the CA coast as an upper cutoff low progresses east into the Great Basin. Northerly winds will steadily increase today along the tightening pressure gradient between the building ridge and departing low.
627 AM CDT Mon Apr 15 2024 (Today and tonight) A mid/upper low located just northeast of Las Vegas, NV early this morning will move northeastward over southeastern Utah this morning and then to the Colorado Front Range this afternoon.
414 AM PDT Mon Apr 15 2024 A cold front will bring a return of cooler and showery weather early this week. Warmer, dry weather is expect to return later this week. Today and Tuesday: A potent cold front has crossed the Cascade crest which will usher in cooler temperatures and windy conditions today. Tuesday is anticipated to be the coldest day of the week, with afternoon highs ranging from the low to mid-50s and a 40% chance of showers in the Cascades and Panhandle.
502 AM EDT Mon Apr 15 2024 A cold front will drop south this afternoon. This front lifts back north as a warm front on Tuesday in advance of the next low pressure system expected to approach the region by the middle of the week. Current surface analysis has a cold front draped from east to west across southern Pennsylvania with areas of thunderstorms still ongoing as far south as Maryland. Temperatures already starting on the warmer side and have been running several degrees above guidance already this morning.
642 AM CDT Mon Apr 15 2024 (Today through Tuesday) Record highs are possible today as a strong ridge axis extending from the Gulf of Mexico to the Upper Midwest builds eastward across Tennessee. Wind speeds will be much lower today as the high pressure builds across the area. BNA climate data for today: Normal high 73 Forecast 87 Record 87 from 1936 BNA climate data for Tuesday: Normal high 73 Forecast 87 Record 88 from 1955 The warm conditions will continue tonight and Tuesday under the strong ridge.
639 AM EDT Mon Apr 15 2024 A cold front will drop south this afternoon. This front lifts back north as a warm front on Tuesday in advance of the next low pressure system expected to approach the region by the middle of the week. Current surface analysis has a cold front draped from east to west across southern Pennsylvania with areas of thunderstorms still ongoing as far south as Maryland. Temperatures already starting on the warmer side and have been running several degrees above guidance already this morning.
607 AM CDT Mon Apr 15 2024 (Today through Tuesday) 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. In fact, highs on Tuesday will be well above normal, as the approach of a weak cold front produces a downsloping effect off of the high terrain of neighboring Mexico. Meanwhile, additionally at the surface, an enhanced pressure gradient will exist courtesy of high pressure over the Gulf of Mexico interacting with low pressure over Mexico.
530 AM MDT Mon Apr 15 2024 - A late winter storm moves over the forecast area today bringing much cooler temperatures and rain and snow showers. Meanwhile, the cold front associated with this system was oriented north-south along a line just east of Page (AZ), Price (UT) and Fort Bridger (WY). This will drive the cold front to the western Colorado border by 12Z and to the Divide by midday. Dynamic forcing from the surface to jet level indicated as the storm moves in and as a result, showers become numerous over the mountains with more scattered coverage over the lower elevations.
502 AM PDT Mon Apr 15 2024 Low cloud cover is the predominant condition for this morning with lingering moisture after this weekend's showers, and a weak, weakening cold front making its way across northern Oregon. The low level moisture may be sufficiently deep, and lift sufficiently strong for a few drizzly showers at the Coos and Douglas coast until around 11 AM. The low clouds are expected to linger longest in the Coquille and Umpqua valleys, into this afternoon.
615 AM CDT Mon Apr 15 2024 (Today) Mid level ridging will build in from the west throughout the day today.
It was a little chilly this morning with the lowest temps dipping into the low to mid 50's. It's also warming up nicely under sunny skies as high pressure remains over the area. High pressure located near Bermuda ridges west-southwest over Florida and into the Gulf of Mexico.
(Rest of Today) The combination of an upper ridge over the western Gulf coupled with a Bermuda high stretching into the eastern Gulf Coast will maintain quiet/seasonably warm wx conditions into the afternoon hrs. Current temps have already rebounded into the lower/mid 60s, from their earlier lows mainly in the upper 40s/lower 50s. Temps later today look to climb predom into the lower/mid 80s, which is close to 10F above normal for this time of the yr.
326 AM MDT Mon Apr 15 2024 - A late winter storm moves over the forecast area today bringing much cooler temperatures and rain and snow showers. Meanwhile, the cold front associated with this system was oriented north-south along a line just east of Page (AZ), Price (UT) and Fort Bridger (WY). This will drive the cold front to the western Colorado border by 12Z and to the Divide by midday. Dynamic forcing from the surface to jet level indicated as the storm moves in and as a result, showers become numerous over the mountains with more scattered coverage over the lower elevations.
High pressure persists over the western Atlantic, with the ridge axis extended toward the Florida peninsula. High pressure will remain in control through mid week with a dry airmass in place and warming temperatures.
540 AM CDT Mon Apr 15 2024 (Today through Tuesday) Dry weather for the next two days with temperatures in the low to mid 80s today. There will be a little bit more cloud cover on Tuesday with the advancement of a system expected Tuesday night, so temperatures may be a few degrees cooler on Tuesday, but remain in the 80s across much of the area.
230 AM PDT Mon Apr 15 2024 Dry and warmer weather returns this week. Ridging from the eastern Pacific is expected to move overhead through the remainder of the week keeping troughiness to the north at bay. Temperatures will be milder today reaching the lower 70s across portions of the Central Valley, and into the lower 80s by midweek.
214 AM PDT Mon Apr 15 2024 A cold front will bring a return of cooler and showery weather early this week. Warmer, dry weather is expect to return later this week. Today and Tuesday: A potent cold front has crossed the Cascade crest which will usher in cooler temperatures and windy conditions today. Tuesday is anticipated to be the coldest day of the week, with afternoon highs ranging from the low to mid-50s and a 40% chance of showers in the Cascades and Panhandle.
(Today through Tuesday night) For today and tonight, a vigorous upper level low pressure system initially progged to be centered around the vicinity of southern Utah and northern Arizona at 12Z this morning is forecast to move to around northwestern or north central Kansas by 12Z Tuesday. A surface dryline is expected to be located across the far eastern zones this afternoon, then retreat westward some this evening before being overtaken by a Pacific cold front later tonight. Low pops offered by the NBM for tonight across only the far eastern zones also look reasonable based on the expected location of the Pacific cold front overtaking the retreating dryline.
630 AM CDT Mon Apr 15 2024 (Today through Tuesday) Early morning upper air pattern showed upper ridging from south Texas to the Dakotas, with an upper low centered near Las Vegas. At the surface, high pressure extended from near Bermuda westward across much of the northern Gulf of Mexico. The axis of the upper ridge will shift to the east of the area on Tuesday, as the upper low near Las Vegas lifts northeastward to near Omaha by Tuesday evening.
19Z water vapor imagery showed a closed upper low over the four corners region with a tropical fetch of moisture streaming into the central plains from the Gulf of California. Tuesday afternoon and evening, models have some warp around moisture within the closed low moving across north central KS.
257 PM EDT Mon Apr 15 2024 High pressure will lead to unseasonably warm and quiet weather through midweek. The former providing the warmth in the low levels while the latter keeps the column extremely dry. Quiet forecast continues, with the offshore high pressure and Gulf ridging maintaining an influence on the area. Biggest thing to note is an increase in cloud cover this period, due to a weak cold front approaching from the west.
Today through the reminder of the week: As the upper low continues to slowly track east into the central Great Basin, thicker clouds and shower chances will continue to decrease over western NV and the Sierra through this evening into Tuesday. Overnight lows will also be on the rise, generally above the freezing mark for once. Higher elevations like Mammoth Mountain will still not see highs break out of the upper 40s with overnight lows staying for the most part below freezing through the week. Freezing fog looks to burn-off my mid-morning Tuesday.
Highs on Tuesday warm back into the lower and middle 80s inland with upper 70s along the immediate coastal interface.
high level clouds associated with a low pressure system. especially underneath the low clouds. the low clouds are progged to break up some across Eastern Oklahoma while the high clouds remain over the region. afternoon temps will be cooler compared to yesterday with highs in the 70s to low 80s forecast.
(This evening through Tuesday Night) Upper ridging remains in place over the region. The upper ridge will shift east of the region by this evening, and then we will transition into SW Flow aloft ahead of an approaching trough and associated frontal boundary. By tomorrow, the aforementioned trough will start to eject into the Northern Plains.
A low pressure system will slide across northern Arizona today, bringing gusty winds, cooler temperatures and isolated showers across far northern Arizona. Warmer and drier weather set to return for the rest of the week. An upper level low is spinning just north of the Four Corners early this afternoon bringing a cool and breezy day to the area, with little in the way of precipitation. Thanks to the passage of the low, today will be the coldest day of the week with temperatures remaining 5 to 8 degrees below normal. A quieter weather pattern is in store the rest of this week with significantly warmer temperatures.
Expect highs generally in the low to mid 80s this afternoon. Under mostly cloudy skies areawide, high temperatures are forecast to climb in the lower 80s.
(Rest of today through Tuesday) A rather strong mid level ridge centered over the southwestern Gulf of Mexico will extend eastward towards South Florida through the rest of this afternoon and into Tuesday. At the surface, high pressure centered over the western Atlantic will keep an easterly wind flow in place during this time frame. High temperatures on Tuesday will rise into the lower 80s across the east coast metro areas, and into the mid to upper 80s across Southwest Florida.
- Turning cooler through the week and into the weekend, with off and on precipitation chances. Returning moisture and diurnal heating ahead of an upper low has pushed MLCAPE values as high as 3000J/kg in southwestern portions of the area. Storms push to our east Tuesday morning, but additional showers and thunderstorms are expected to develop as the upper low moves through the area. Winds will turn to the northwest behind the low Tuesday evening into the overnight, and gusts of 40-50 MPH are expected.
A area of low pressure in eastern Idaho and high pressure off the coast will enhance the winds today, becoming very windy in southern Idaho (east of Boise) where a Wind Advisory is in effect this afternoon and evening. The bulk of showers associated with an upper low will remain mainly to our east, but isolated light showers or sprinkles are expected over SW Idaho today.
1126 AM EDT Mon Apr 15 2024 A weak cold front moves across the region today with a few showers possible.
This Evening through Tuesday: A strong upper level trough will move through the Central Rockies and Plains tonight and Tuesday. Ahead of the trough, the axis of an upper level ridge will move eastward from Texas coast, arriving in Georgia on Tuesday. Subsidence from the ridge should keep dry weather in place for Georgia through Tuesday afternoon. Increased ridging (rising 500 mb heights) and subsidence would generally suggest warmer temperatures.
330 PM EDT Mon Apr 15 2024 High pressure will persist across the area through tonight.
146 PM EDT Mon Apr 15 2024 High pressure will bring dry and mild conditions through Tuesday.
Temperatures will continue to trend downward with highs on Tuesday about 10-15 degrees cooler than today. An upper trough drops into the Northern Rockies on Tuesday night along with a backdoor cold front coming across the Divide.
A developing low- level jet coupled with weak forcing along a cold front look to be the main ingredients for these low POPs. The warm S/SW flow at the mid levels com- bined with steady S/SE winds at the surface will help to warm the high temperatures tomorrow into the lower and mid 80s. Lows tonight and to- morrow will be in the lower 70s.
Upper level ridging continues to stretch from the western Gulf of Mexico northward through the Mississippi River Valley to start the forecast period. High pressure located near Bermuda ridges west-southwest over Florida and into the Gulf of Mexico. High pressure dominates the weather over the area with warm and rain- free conditions through the week.
Temps are running a couple degrees cooler than yesterday at this time due to much higher low level moisture with dewpoints now in the upper 50s to low 60s, along with a bit of cloud cover. Winds and cloud cover will increase tomorrow at all levels as a powerful upper level low moves out of the Plains into the Midwest.
253 PM EDT Mon Apr 15 2024 High pressure will bring dry and mild conditions through Tuesday.
Latest observations indicate temperatures already pushing into the low to mid 80s across Deep South Texas and the Rio Grande Valley this morning. (Today through Tuesday) 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. In fact, highs on Tuesday will be well above normal, as the approach of a weak cold front produces a downsloping effect off of the high terrain of neighboring Mexico. Meanwhile, additionally at the surface, an enhanced pressure gradient will exist courtesy of high pressure over the Gulf of Mexico interacting with low pressure over Mexico.
As the upper low to the southeast continues to shift eastward out of the area and a weak front moves inland to the north, we will continue to see cloudy and cool conditions through much of the day.
Southerly surface flow was advecting a warm and humid airmass into the region, characterized by dewpoints in the low to mid 60s. Another round of storms could occur overnight as a cold front will sweep through the area, but this will be dependent on how much storm coverage occurs during the evening. Highs tomorrow should be in the upper 80s to low 90s, although heat index values should be lower due to the lower humidity.
1139 AM MDT Mon Apr 15 2024 - A late winter storm moves over the forecast area today bringing much cooler temperatures and rain and snow showers. Meanwhile, the cold front associated with this system was oriented north-south along a line just east of Page (AZ), Price (UT) and Fort Bridger (WY). This will drive the cold front to the western Colorado border by 12Z and to the Divide by midday. Dynamic forcing from the surface to jet level indicated as the storm moves in and as a result, showers become numerous over the mountains with more scattered coverage over the lower elevations.
1216 PM CDT Mon Apr 15 2024 (Today through Tuesday) Dry weather for the next two days with temperatures in the low to mid 80s today. There will be a little bit more cloud cover on Tuesday with the advancement of a system expected Tuesday night, so temperatures may be a few degrees cooler on Tuesday, but remain in the 80s across much of the area.
1223 PM CDT Mon Apr 15 2024 A ridge of high pressure will keep conditions dry today. Above normal temperatures are expected to warm into the low to middle 80s.
(Through Tuesday) High pressure conditions will continue through the rest of today and tonight with mostly clear skies, dry weather, and mild winds persisting through the forecast area.
1256 PM PDT Mon Apr 15 2024 Dry and warmer weather through the week. Cloud coverage is expected to continue to decrease as we move into the evening and overnight hours as the departing low pressure continues to move eastward into the Four Corners. Ensemble guidance continues to project upper level ridging to develop over the eastern Pacific as the dominant synoptic pattern in the short term. As the ridging continues to build over our area, cloudiness should also start to diminish as we move through the week.
1150 AM CDT Mon Apr 15 2024 (Rest of Today) The combination of an upper ridge over the western Gulf coupled with a Bermuda high stretching into the eastern Gulf Coast will maintain quiet/seasonably warm wx conditions into the afternoon hrs. Current temps have already rebounded into the lower/mid 60s, from their earlier lows mainly in the upper 40s/lower 50s. Temps later today look to climb predom into the lower/mid 80s, which is close to 10F above normal for this time of the yr.
1128 AM PDT Mon Apr 15 2024 A cold front will bring a return of cooler and showery weather early this week. Warmer, dry weather is expect to return later this week. Today and Tuesday: A potent cold front has crossed the Cascade crest which will usher in cooler temperatures and windy conditions today. Tuesday is anticipated to be the coldest day of the week, with afternoon highs ranging from the low to mid-50s and a 40% chance of showers in the Cascades and Panhandle.
Onshore flow will maintain plenty of clouds and cooler temperatures across the region for next few days, along with a few showers. High pressure builds across region for Wed to Fri, with return of mild dry weather.
- Strong northwest winds develop Tuesday and Tuesday evening behind a cold front, with wind gusts as high as 60 miles per hour across the southern Panhandle and far southwest Nebraska.
Meanwhile, the mid-level ridge over the Gulf will reestablish its eastward extent over the Florida Mainland by the middle of the week, continuing through the weekend. From synopsis, high pressure will slide into the west- central Atlantic. A secondary high pressure moving in from the the Gulf and eventually over Florida will result in modestly slackened east to southeast breezes for the end of the week and into the weekend.
A low pressure system will slide across northern Arizona today, allowing gusty winds, cooler temperatures and isolated showers. Warmer and drier weather set to return for the rest of the week. Low pressure centered over east-central Utah will continue moving east into Colorado through the remainder of the afternoon. The center of a large low pressure system will slide west to east across the AZ/UT border today. This area of low pressure will quickly push eastward on Tuesday, allowing drier conditions and warmer temperatures to return.
1004 AM CDT Mon Apr 15 2024 - There is a 50% chance for areas to see greater than an inch of rainfall tonight through Tuesday night, with the highest chances across southeast North Dakota and west central Minnesota. Dry air in the lower levels will limit the amount of rain making it to the surface, keeping amounts under quarter of an inch today.
Windy weather will develop on Tuesday as a cold front approaches the region.
(This evening through Tuesday night) Upper ridging axis curves from the northern plains, through the central midwest, and into the northwest gulf. A low pressure sink is centered just north of the four-corners. As we move through the short term, the low moves over the upper midwest trailing a frontal boundary that should be maturing but forced by the high pressure over the Gulf to sit north of us by the end of the short term.
Upper level ridging over the Northern Plains ahead of an upper level low over the Four Corners region is driving the weather the rest of today. Upper divergence and mid level warm air advection is helping scattered rain showers this afternoon into evening, although dry air in the low levels is preventing or delaying rainfall. The low level jet increases further to 60+ kt into the day Tuesday over this same area as the low continues to deepen and strengthen, but becomes more rooted at 850 mb. As the upper low pulls moisture around itself, widespread rainfall chances envelop the region. 0 inches reside within the Devils Lake basin where inverted trough stalls, as well as toward west-central Minnesota closer to the feed of better moisture/weak instability.
Latest analysis shows the cold front dropping through the Susquehanna Valley this afternoon toward the PA/MD border. High pressure will settle overhead tonight while the boundary drops off to our south. High pressure both at the surface and aloft will remain overhead for Tuesday, bringing dry and mild conditions along with sunshine. Highs will range from the 60s in northern PA as well as the ridges to the lower and middle 70s for most other locations.
Another round of scattered showers and a few storms is expected ahead of cold front after midnight across E OK, with this activity then progressing east into western AR into Tuesday morning. Skies will clear behind the morning showers and storms, and mixing of strong SW winds aloft at the base of the advancing upper low/trough will lead to a pretty windy day across the area.
Dry Tuesday on through the week with temperatures trending warmer.
