651 AM EDT Tue Apr 9 2024 - Scattered showers and a thunderstorm or two, mainly this morning - Gusty afternoon winds and low RH values today, especially over northeast Lower - Possible widespread measurable rain near the end of the work week Pattern Synopsis/Forecast: A vertically stacked/occluded low pressure system is currently centered over northwest Ontario, with the associated occluded/cold front extending south across Wisconsin and Illinois. It will be cooler tonight behind the front, but above normal readings in the mid- upper 30s are still expected. Pattern Synopsis and Forecast: Midlevel split flow pattern currently over North America with northern branch flow around the 60th parallel continues to keep cooler polar air to the north and open the CONUS to a warmer Pacific mass. Weather starts off the short term period quiet ahead of the second upstream trough.
Warm and rain-free conditions today with ridging over the region as potent southern stream storm system continues to develop in the Desert SW and move into W TX. Ridging continues to dominate our weather pattern to start the week.
703 AM PDT Tue Apr 9 2024 Upper level high pressure builds today, dissipating the weak system over the area.
640 AM EDT Tue Apr 9 2024 High pressure will move farther off the coast over the next couple days, bringing warmer and more humid weather.
953 AM EDT Tue Apr 9 2024 A weak warm front is moving through bringing widespread mid and high clouds to the region with a few isolated sprinkles late this afternoon and evening. Tomorrow is looking warm ahead of our next low pressure system that is moving in mid week bringing rain and wind late week. A quick temperature recovery has happened after temperatures got a little cooler than forecast this morning. High pressure will bring mostly sunny skies today and temperatures will soar into the 70s this afternoon.
An upper low is parked just south of the Arizona/New Mexico/Mexico border with southwesterly mid level flow ahead of it. As the day progresses today, the upper low will eject out of the southwest CONUS with additional subtle disturbances ahead of it supporting another wave of showers and storms overnight into Wednesday morning.

752 AM EDT Tue Apr 9 2024 (Today through Wednesday) High pressure over the western Atlantic will remain in control today, resulting in yet another pleasant day of dry weather in South Florida. Highs on Wednesday will start to increase, rising into the low to mid 80s across the East Coast, and into the upper 80s to around 90 across interior and Gulf Coast areas.
A weak upper low over the International Border in Santa Cruz/Cochise counties will track east across Northern Chihuahua/Southern New Mexico today. This is a low confidence event though as the pace of the upper low moving east may outpace any disturbance wrapping around into the area.
A weak weather disturbance and its associated cold front will bring cooler temperatures and a chance of precipitation for Wednesday. Models continue to show quieter weather through the middle portion of the week, with the only minor forecast concern Tuesday night and Wednesday in the form of the next Pacific cold front quickly moving across the area. This will change later tonight as the Pacific cold front and associated progressive upper level trough axis slides southeast into Montana and Wyoming. The upper level trough will then dig south and slow down through the day, allowing scattered showers to continuously develop through the day and into the early evening hours.
303 PM EDT Tue Apr 9 2024 High pressure will move farther off the coast over the next couple of days, bringing warmer and more humid weather.
151 PM MDT Tue Apr 9 2024 - A weather disturbance and its associated cold front will bring cooler temperatures and a chance of precipitation for Wednesday.

Tomorrow is looking warm ahead of our next low pressure system that is moving in mid week bringing rain and wind late week. A quick temperature recovery has happened after temperatures got a little cooler than forecast this morning. High pressure will bring mostly sunny skies today and temperatures will soar into the 70s this afternoon. A stacked closed low up to 500mb over the east-central US will be the main weather driver for this period. The deep trough will dig into the Gulf of Mexico, tapping into tropical moisture.
349 PM EDT Tue Apr 9 2024 High pressure will move farther off the coast over the next couple of days, bringing warmer and more humid weather.
243 PM MDT Tue Apr 9 2024 - Gusty (20-30 mph) north winds at many locations Wednesday as cold front drops south through the area.
430 PM EDT Tue Apr 9 2024 High pressure will exit across the Maritimes tonight through Wednesday.
130 PM EDT Tue Apr 9 2024 A weak warm front is moving through bringing widespread mid and high clouds to the region with a few isolated sprinkles late this afternoon and evening. Tomorrow is looking warm ahead of our next low pressure system that is moving in mid week bringing rain and wind late week. A quick temperature recovery has happened after temperatures got a little cooler than forecast this morning. High pressure will bring mostly sunny skies today and temperatures will soar into the 70s this afternoon.
(Wednesday through Tuesday) Shower and storm development will be ongoing Wednesday morning and will continue through the afternoon as the upper system swings through the southern plains Highest rain totals will be favored across SE OK given the track of the system and cold core development that takes place under the upper low.
PW values will be max for this time of year, with scattered convection moving southwest to northeast around a high pressure over the eastern coast. Temperatures will be colder today due to the continuous cloud cover, with highs in the low 60s to mid 70s and lows in the upper 50s to lower 60s tonight.
(This evening through Wednesday) An upper level low and associated vort max, just south of El Paso, will track northeast across West Texas this evening and overnight. As the upper low moves eastward across northern Texas on Wednesday, surface winds will become more northerly, especially across the western Oklahoma during the morning.
These clouds were occasionally moving over Island communities and blocking out the sun for very brief time periods. Temperatures along the Island Chain are in the upper 70s to lower 80s with dew points in the lower to mid 60s.
Lows tonight will be seasonably mild mainly in the mid to upper 50s with highs on Wednesday seasonally warm in the low to mid 70s, around 70 Cumberland Plateau Region.
Pattern Synopsis/Forecast: A vertically stacked/occluded low pressure system is currently centered over northwest Ontario, with the associated occluded/cold front extending south across Wisconsin and Illinois. It will be cooler tonight behind the front, but above normal readings in the mid- upper 30s are still expected. Pattern Synopsis and Forecast: Midlevel split flow pattern currently over North America with northern branch flow around the 60th parallel continues to keep cooler polar air to the north and open the CONUS to a warmer Pacific mass. Weather starts off the short term period quiet ahead of the second upstream trough.
(18Z TAFS) A well established southeast flow is in place between high pressure to the east and low pressure taking shape over TX. /10 (Now through Wednesday) Latest water vapor imagery shows the forecast area under weak upper ridging, with a closed low moving into the TX/OK Panhandles and a closed low over the Upper Mississippi Valley. Temps will be on the mild side, given extensive cloud cover, with lows in the lower to mid 60s. The upper ridge will strengthen a bit through the day as the southern stream low digs into the Southern Plains. With the moisture continuing to stream into the area, and weak waves ejecting from the low to our west, isolated to scattered showers are possible over our northern zones. That said, the influence of the strengthening ridge should limit the coverage of showers today.
1147 AM EDT Tue Apr 9 2024 High pressure will cross the region today.
High pressure will build over the region over the next couple days leading to a rapid warming trend and temperatures easily rising into an above normal category starting Wednesday.
255 PM MDT Tue Apr 9 2024 Showers of rain and mountain snow will come to an end this evening as a high pressure system pushes into the area.
Showers linger in a Puget Sound Convergence Zone into the day, but otherwise a break in the weather with an upper ridge developing over the region. This will bring warmer and drier conditions through the middle of the week. Another cooler and more active weather system then returns late in the week.
(This evening through Wednesday night) The upper level low pressure system responsible for the rain and isolated thunderstorms today across mainly the southern half of the Texas Panhandle was moving across far west Texas as of this writing. Will mention there is a dry slot seen on water vapor satellite imagery developing to the southwest closer to the upper level low, and this will need to be monitored this evening and tonight to see if our forecast area becomes impacted or if it remains south of the region.
A low pressure system is moving easterly out of the Southwest region which is currently bringing very light showers to mainly virga in the White Mountains.
Have also lowered pops through mid-afternoon before the shower/storm potential returns as an upper level low over far west Texas approaches the Texas Panhandle.
A weak system passing by mainly to our north will bring a 30-50 percent chance of light rain/snow to the higher elevations of Baker County into the West Central ID mountains (McCall) today.
This is all occurring along a stalled warm front. However, they do not seem to be picking up on a secondary area of moderate to heavy rainfall that is redeveloping and moving ENE from Mississippi into the area near this warm front.
Additional areas of light to moderate rainfall continue to be seen upstream of the area along this warm front on radar data. Expect this to continue, but for the warm front to begin to move northward into central or northern Tennessee around 9 or 10 PM.
Expect gusty westerly winds of about 25 mph in the higher terrain and over Flathead Lake this afternoon and evening. Precipitation will decrease rapidly with sunset as a ridge of high pressure begins to build over western Montana and north central Idaho tonight.
(Rest of today through Wednesday) South Florida will remain under the influence of upper level ridging and an area of high pressure for the rest of the day, allowing for pleasant weather conditions to continue. The pattern begins to change tomorrow as an area of low pressure begins to track across the Gulf states. As this low progresses over the Ark-La-Tex region, a series of associated fronts will approach across the Gulf of Mexico. High temperatures today will reach the low-mid 80s across the region, but they could rise to the upper 80s tomorrow as southerly flow prevails.
343 PM EDT Tue Apr 9 2024 With mostly sunny skies, temperatures have warmed into the low 70s for much of the area. Tomorrow will be cooler with more clouds and isolated to scattered showers.
Short-term progs all continue to suggest the development of QLCS across South Texas tonight ahead of a closed trough shifting east through the southern Panhandle of Texas. However, more storms are possible as the closed trough moves into the region, especially north of I-20 closer to the track of the closed trough. Hail would likely be the higher threat, as most of that convection should be elevated. Drier and noticeably cooler weather will move into the area late Wednesday night, as the trough and associated cold front move out of the region.
Another system moves in late week into the weekend, bringing cooler weather and more rain.
Temperatures this afternoon remain below normal across a large portion of the area located behind the surface cold front. Warmer temperatures hold on further to the south ahead of this front. Much quieter weather returns on Wednesday as the last of the clouds clear, allowing for warmer temperatures and sunnier skies.
(This evening through Wednesday) An upper low currently centered near El Paso is driving showers and thunderstorms across portions of the forecast area. While there is PVA/forcing downstream of the upper low and mesoanalysis currently indicates about 250-500 J/kg of MUCAPE present over much of the region, the drier air and lack of remaining daytime heating (unlike yesterday) should inhibit the development of any stronger storms.
We have a busy surface pattern with a warm front feature from the Pine Belt to near I-20 west of Vicksburg.
Ridging over the area will keep the warm conditions in place tonight into Wednesday with occasionally breezy daytime winds. The potent southern stream upper low will continue to spin through TX and the S Plains Wednesday further developing the W Gulf surface storm system with significant upper dynamics to produce active and severe weather through the S Mississippi River Valley Wednesday with a tightening pressure gradient over the E Gulf and FL Peninsula increasing mean layer moisture on strong southerly low level flow through Wed night.
Another day of brisk northwest winds as short wave continues to track across the high plains in northwest flow. Despite some weak lift over the area, the lower levels will be a little drier without much CAPE. Highs Wednesday will be a bit cooler than Tuesdays with readings in the mid 40s to lower 50s. Lows Wednesday night will be in the lower 30s west to mid 20s east.
Also, make some adjustments to temps, as rain has kept things a little cooler than originally anticipated.
724 PM EDT Tue Apr 9 2024 High pressure will exit across the Maritimes tonight through Wednesday.
1037 PM EDT Tue Apr 9 2024 High pressure will move farther off the coast over the next couple of days, bringing warmer and more humid weather.
704 PM EDT Tue Apr 9 2024 (Rest of today through Wednesday) South Florida will remain under the influence of upper level ridging and an area of high pressure for the rest of the day, allowing for pleasant weather conditions to continue. The pattern begins to change tomorrow as an area of low pressure begins to track across the Gulf states. As this low progresses over the Ark-La-Tex region, a series of associated fronts will approach across the Gulf of Mexico. High temperatures today will reach the low-mid 80s across the region, but they could rise to the upper 80s tomorrow as southerly flow prevails.
1005 PM EDT Tue Apr 9 2024 High pressure will exit across the Maritimes tonight through Wednesday.
A weak storm system will bring cooler weather, rain, and wind late week into the weekend. High pressure has continued to spread across the area. High pressure will continue to build tomorrow bringing a distinctly summer like character to the weather. Many interior valleys will reach the low 80s though NBM shows essentially 0% chance of any location reaching 90.
High pressure in the western North Atlantic has shifted far enough eastward over the past 24 hours that we have begun to lose the source of the modified continental airmass that we have been enjoying for the past few days. Dew points have jumped up to 65 degrees tonight, which is still slightly below normal, but also the highest we have seen since last week's frontal passage.
506 PM MDT Tue Apr 9 2024 - A weather disturbance and its associated cold front will bring cooler temperatures and a chance of precipitation for Wednesday.
730 PM EDT Tue Apr 9 2024 High pressure will move farther off the coast over the next couple of days, bringing warmer and more humid weather.
637 PM CDT Tue Apr 9 2024 (This evening through Wednesday) An upper low currently centered near El Paso is driving showers and thunderstorms across portions of the forecast area. While there is PVA/forcing downstream of the upper low and mesoanalysis currently indicates about 250-500 J/kg of MUCAPE present over much of the region, the drier air and lack of remaining daytime heating (unlike yesterday) should inhibit the development of any stronger storms.
556 PM CDT Tue Apr 9 2024 (This evening through Wednesday) An upper level low and associated vort max, just south of El Paso, will track northeast across West Texas this evening and overnight. As the upper low moves eastward across northern Texas on Wednesday, surface winds will become more northerly, especially across the western Oklahoma during the morning.
Winds will decrease overnight as an upper level ridge approaches from the west.
617 PM CDT Tue Apr 9 2024 (This evening through Wednesday night) The upper level low pressure system responsible for the rain and isolated thunderstorms today across mainly the southern half of the Texas Panhandle was moving across far west Texas as of this writing. Will mention there is a dry slot seen on water vapor satellite imagery developing to the southwest closer to the upper level low, and this will need to be monitored this evening and tonight to see if our forecast area becomes impacted or if it remains south of the region.
High pressure building into the area will result in a drying and warming trend which will continue through the remainder of the week. Utah remains under a northwesterly flow aloft this afternoon, between a low pressure system exiting east into Texas and high pressure building into the West Coast. Clouds are increasing over northern Utah ahead of this trough, and there may be isolated shower activity across the northern Utah mountains through tonight. The upstream ridge will continue to slowly build inland, leading to dry conditions along with a continued warming trend.
Showers of rain and mountain snow will come to an end this evening as a high pressure system pushes into the area.
349 AM EDT Wed Apr 10 2024 Today will be cooler with more clouds and scattered showers.
The northwest flow will keep temperatures a bit cooler than Tuesday, in the low to mid 50s with a few 40s across SE Montana.
The ridge that has dominated our weather pattern the past several days continues to shift off to the east and the approaching trough is constricting the pressure gradient over the region.
1227 AM EDT Wed Apr 10 2024 High pressure will exit across the Maritimes through Wednesday.
(Today and tonight) The mid/upper level low/trough that has brought showers and thunder to the forecast area the last 24 to 36 hours is clearly defined on satellite imagery extending from western Oklahoma to the Permian Basin. Radar imagery continues to show a band of light to moderate rain wrapping around the back side of the trough. Models are in good agreement with the trough shifting eastward to central Oklahoma and northwest Texas by noon today and then east of the I-35 corridor by the end of the day. Despite some low level cold advection, clearing skies mid morning to early afternoon will result in increased insolation and warmer temperatures relative to yesterday and in line with NBM highs.
1147 PM MDT Tue Apr 9 2024 - Gusty (20-30 mph) north winds at many locations Wednesday as cold front drops south through the area.
(Today and tonight) The cooler, more stable air mass behind the cold front will allow for a break from the severe weather. Temperatures today will be below normal, with highs in the low 60s to low 70s and lows in the 40s tonight.
955 PM MDT Tue Apr 9 2024 - A weather disturbance and its associated cold front will bring cooler temperatures and a chance of precipitation for Wednesday.
Perhaps the highest elevations in the northern mountains could see and inch or two by the afternoon. This system also brought a slightly cooler temperatures into the region so highs today should be similar to yesterday. Tomorrow the ridge of high pressure builds in from the west allowing temperatures to warm up by 5-10 degrees.
1236 AM CDT Wed Apr 10 2024 (This evening through Wednesday) An upper low currently centered near El Paso is driving showers and thunderstorms across portions of the forecast area. While there is PVA/forcing downstream of the upper low and mesoanalysis currently indicates about 250-500 J/kg of MUCAPE present over much of the region, the drier air and lack of remaining daytime heating (unlike yesterday) should inhibit the development of any stronger storms.
1258 AM CDT Wed Apr 10 2024 (This evening through Wednesday night) The upper level low pressure system responsible for the rain and isolated thunderstorms today across mainly the southern half of the Texas Panhandle was moving across far west Texas as of this writing. Will mention there is a dry slot seen on water vapor satellite imagery developing to the southwest closer to the upper level low, and this will need to be monitored this evening and tonight to see if our forecast area becomes impacted or if it remains south of the region.
141 AM EDT Wed Apr 10 2024 High pressure will move farther off the coast over the next couple of days, bringing warmer and more humid weather.
A low chance for marginally severe hail will exist in the afternoon across mainly southeast Oklahoma given the proximity to the upper low center and the colder temperatures aloft.
High pressure off to our northeast is promoting fresh east to southeast breezes across our marine observation platforms. The high in the western North Atlantic will continue to dominate today's pattern.
(Today and tonight) Periods of scattered showers and a few thunderstorms are expected today as the center of the closed upper low translates across north Texas. Guidance has trended cooler for temperatures today due to plentiful cloud- cover, rain, and CAA. Breezy north winds are also expected with gusts increasing over southern and southeastern Oklahoma this afternoon as the surface cyclone deepens to our southeast.
Warmer temperatures will build in today and tomorrow with afternoon highs climbing several degrees above normal.
1145 PM CDT Tue Apr 9 2024 (This evening through Wednesday) An upper level low and associated vort max, just south of El Paso, will track northeast across West Texas this evening and overnight. As the upper low moves eastward across northern Texas on Wednesday, surface winds will become more northerly, especially across the western Oklahoma during the morning.
A squall line is moving across the northern Gulf Coast ahead of a potent mid to upper level low. CIMSS mean layer products and water vapor imagery place the center of a mean layer ridge over the Caribbean, with anticyclonic flow noted at all levels across the Keys. The next weak cold front will push through the Keys Thursday night, with a slight chance of showers and thunderstorms ahead of the front. From synopsis, high pressure centered near Bermuda will maintain fresh southeast breezes across the Florida Keys today. In the wake of the front, breezes will shift to the northeast to east as another high pressure system moves across the Southeast and into the western North Atlantic late.
Wet and unsettled weather will continue for the next 24-36 hours as a cold front and deep low pressure system traverse the area.
