159 AM EDT Fri Apr 11 2025 A low pressures system moving through the Tennessee Valley will bring a chance of showers to areas along and south of the Ohio River tonight. High pressure and a dry but cooler airmass will build into the region for Friday. With a fair amount of lingering low level moisture, clouds will persist through the morning hours and into early afternoon, but we may begin to see a decreasing cloud trend from the west later in the afternoon as the high builds in. As the high moves overhead Friday night, mostly clear skies and decreasing winds are expected. This will lead to areas of frost late as temperatures drop into the low to mid 30s.
1229 AM CDT Fri Apr 11 2025 - Warmer than normal temperatures Friday through the weekend.
1153 PM CDT Thu Apr 10 2025 (Rest of tonight and Friday) Severe storms triggered by a cold front passage have moved SE of the area as the cold front surged to the FL Peninsula. This will and is quickly bringing in a much cooler and drier air mass with clear skies already making their way into north Alabama and southern middle Tennessee.
These showers were occurring along a cold front that extends northwest across central Illinois into Iowa. The low clouds that is associated with the front will likely stick around through midday which will have an impact on temperatures, so have dropped going highs back by a few degrees.
The showers and storms remain ahead of a cold front that will dip south across the region throughout the day. After we get past today, the forecast will generally be dry and cooler.
1149 PM CDT Thu Apr 10 2025 (This evening through Friday Night) With a steady onshore flow pattern in place and a gradual trend of warmer and more humid conditions over the past several days, this afternoon's conditions have reflected the inactive trend of late with highs in the lower 80s and dew points approaching the 60 mark. A brief pattern shift arrives overnight in the form of a weak cold front, which will move through the region before pushing offshore by early tomorrow morning. Mild, drier conditions remain in place tomorrow with highs rising into the low to mid 80s across most of the area.
(Today and tonight) Not too much changes today relative to yesterday as an upper level ridge over the intermountain West moves slowly eastward. Surface ridging will also shift to the east with winds veering to southeast to south, winds increasing slightly this afternoon as the pressure gradient begins to tighten.
1227 AM CDT Fri Apr 11 2025 - Weak cold front moves through this afternoon with low chances (20-35%) for precipitation to occur. - Cooler on Friday, before a gradual warming trend through the weekend.
200 AM EDT Fri Apr 11 2025 High pressure will remain ridged across the region today.
419 AM EDT Fri Apr 11 2025 Expect some showers behind a low pressure system passing to the south.
1151 PM CDT Thu Apr 10 2025 (This evening through Friday night) A cold front and parent trough will continue to slide southward from the Ohio/TN River Valleys tonight and push through our area tomorrow morning. Temperatures will be a skosh cooler during the day and remain below average at night through the period.
1212 AM CDT Fri Apr 11 2025 A large upper trof over the eastern states amplifies through Friday before moving off into the western Atlantic this weekend.
231 AM MDT Fri Apr 11 2025 KEY MESSAGES: * Very warm temperatures and low humidity will prevail across the region today before a low pressure system moves in. * A change in the weather pattern will bring potential for accumulating rain this weekend and cooler temperatures. WEATHER PATTERN OVERVIEW: Synoptic scale model data (GFS and ECMWF ensemble) indicate that a brief, strong ridge of high pressure will move across northeast Montana this morning which will move to the east this afternoon. A dry cold front this afternoon will bring gusty west to NW winds which will be strongest in the north.
The associated frontal boundary will continue pushing south across the region through the day today as a strong upper trough digs into the southeastern states.
Troughing aloft remains over the E U. this morning, while surface ridging ridges down the E Seaboard across the state into the Gulf south of a frontal boundary draped across the N Gulf states. Warm conditions expected with highs in the lower to mid 80s.
140 AM EDT Fri Apr 11 2025 - Brief Warm up Then Another Cooldown Deeper moisture is moving off to the east this Thursday afternoon as low clouds and showers persist across the east central zones where a vort max rounds the base of the upper trough. We expect those showers to be ending by early evening as the trough moves east.
1247 AM EDT Fri Apr 11 2025 - Frost is likely with lows near freezing tonight; a hard freeze is possible Friday night.
323 AM CDT Fri Apr 11 2025 - Cooler today and tonight.
- Near freezing lows and frost possible for some early Saturday morning.
High temperatures are expected to be in the lower 60s to mid 70s with overnight lows dropping into the upper 30s to lower 50s across the state.
500 AM CDT Fri Apr 11 2025 - Cooler today and tonight. Patchy frost is possible across the low-lying areas of the eastern Ozarks tonight into Saturday morning.
Troughing aloft remains over the E U. this morning, while surface ridging ridges down the E Seaboard across the state into the Gulf south of a frontal boundary draped across the N Gulf states. Warm conditions expected with highs in the lower to mid 80s. High pressure builds into the region on Saturday as the front departs, with cooler and drier air filtering into the state under mostly sunny skies and continued occasionally breezy conditions particularly during the afternoon. Highs generally 5-8 degrees cooler are expected, mainly in the mid to upper 70s.
607 AM CDT Fri Apr 11 2025 (Friday through Saturday) A benign forecast continues through the short term period as high pressure remains dominate across the ArkLaTex vicinity.
KBYX is detecting light shower activity out in the Straits of Florida and some pulse showers near the Lower Keys this morning with partly to mostly cloudy conditions seen on the island chain. Along the Reef, wind directions early this morning were all in different directions as outflows of Miami drove Upper Keys to north to northwest, convection influenced easterlies in the Middle Keys, and the Lower Keys remained northerly. The 12z sounding did reveal limited moisture, with a PWAT of only an inch, residing mostly in the lower levels of the atmosphere. From synopsis, gentle northerly breezes will become moderate and northwesterly later this afternoon as a dry cold front slowly approaches our local waters.
High pressure over the area today will result in very warm temperatures.
210 AM MST Fri Apr 11 2025 Record breaking heat is likely today under a strong ridge of high pressure aloft. An abnormally hot and dry period for this time of year will continue today, thanks to an amplified ridge centered from the desert southwest through the northern Rockies and high plains. The height anomaly associated with this ridge indicates a strong chance of breaking records, as the 500mb height on the previous evening observed sounding exceeds the max 500mb height in the SPC climatology of upper air observations in Tucson for the day. By Saturday the ridge axis will have shifted east, however positive height anomalies remain.
This afternoon and evening, weather conditions will begin to deteriorate as upper level trough pushes over the region. Troughing aloft remains over the E U. this morning, while surface ridging ridges down the E Seaboard across the state into the Gulf south of a frontal boundary draped across the N Gulf states. Warm conditions expected with highs in the lower to mid 80s. High pressure builds into the region on Saturday as the front departs, with cooler and drier air filtering into the state under mostly sunny skies and continued occasionally breezy conditions particularly during the afternoon. Highs generally 5-8 degrees cooler are expected, mainly in the mid to upper 70s.
These showers were occurring along a cold front that extends northwest across central Illinois into Iowa. The low clouds that is associated with the front will likely stick around through midday which will have an impact on temperatures, so have dropped going highs back by a few degrees. The HREF is also showing a large scale upper ridge building into the area beginning late today through Saturday which will keep the area dry.
We are in a quiet weather pattern with high pressure over the Gulf and mid-level ridging just upstream. A weak cold front will make its way into south Central Texas today, but the supporting Plains air mass won't have a strong southward push and will shift east more than south, leaving the boundary to stagnate and wash out without much play over deep South Texas. Mid-level ridging will edge east and more overhead during the short term. Low temps will range from the upper 50s to the lower or mid 60s.
- Dry and warmer today and Saturday, with high temperatures in the 60s inland from Lake Michigan on Saturday.
959 AM EDT Fri Apr 11 2025 High pressure will remain ridged across the region today.
624 AM CDT Fri Apr 11 2025 (Today through Saturday) Key Messages: - 10% chance of isolated showers late this afternoon and early evening across the western Hill Country and southern Edwards Plateau - Near-critical fire weather conditions Saturday afternoon across the Rio Grande Plains, southern Edwards Plateau, and portions of the Hill Country At midnight a weak cold front was located across the northern Hill Country. High temperatures today and Saturday are forecast to be slightly cooler than yesterday, but still above normal for this time of year.
755 AM EDT Fri Apr 11 2025 High pressure will remain ridged across the region today.
High temperatures should climb into the lower to middle 60s.
635 AM CDT Fri Apr 11 2025 (Today through Saturday) A weak front north of the area will continue to drift south this morning and should get into at least the northern parts of our area shifting winds to the east or northeast, but other than that, the front will not be very noticeable as it will not come with any rain chance, and temperatures will not be much cooler than they have been. High temperatures this afternoon will range from the low and mid 90s west to the lower 80s along the coast. Expect high temperatures a few degrees warmer tomorrow. A backdoor cold front tries to approach from the northeast through the day Saturday, but most likely doesn't make it into the region.
648 AM EDT Fri Apr 11 2025 High pressure will build across the region today through Saturday offering drier and cooler conditions.
The Lower Keys, and western waters of our forecast area, may dodge these showers due to drier air reflected in the lower PWAT values. For the Lower Keys, we have opted to keep the 10 percent PoPs as the dry air should mitigate any showers that try to approach the area. Over the next couple of days, a dry cold front will push down the peninsula and eventually arrive to the Florida Keys area.
659 AM CDT Fri Apr 11 2025 (Today through Saturday Night) A weak cold front will move through Southeast Texas over the next few hours and is expected to push offshore this morning. While temperatures will still be similar to what has been observed the last few days, the lower dew points will make it feel noticeably drier. Saturday night's lows will be slightly warmer as temperatures dip into the 50s north of I-10 and in the 60s south of I-10.
Today through Tonight: Behind the cold front, you can expect lingering morning showers and cooler temperatures for today.
High pressure will slowly begin moving east tonight but not before some more record high temperatures could be broken both today and tomorrow. Expect another day of record or near record high temperatures today before a Pacific trough moving by to our north begins to flatten and push our high pressure ridge off to the east starting tonight.
(Today through Saturday) A cold front is expected to continue sliding south through our area today, looking to be pushed through land areas by mid to late morning. Outside of that, afternoon high temperatures today will be just a touch, a couple degrees, cooler than yesterday. Winds will increase out of the north this afternoon following the cold front, with peak gusts around 20 to 25mph. Saturday will also see cooler MaxT's, low to mid 70s for all, with the cooler air from the front.
527 AM EDT Fri Apr 11 2025 High pressure will remain ridged across the region today.
520 AM EDT Fri Apr 11 2025 High pressure will build across the region today through Saturday offering drier and cooler conditions.
630 AM CDT Fri Apr 11 2025 (Today through Saturday) A cold front is expected to continue sliding south through our area today, looking to be pushed through land areas by mid to late morning. Outside of that, afternoon high temperatures today will be just a touch, a couple degrees, cooler than yesterday. Winds will increase out of the north this afternoon following the cold front, with peak gusts around 20 to 25mph. Saturday will also see cooler MaxT's, low to mid 70s for all, with the cooler air from the front.
The upper level ridge progresses slightly eastward and begins to weaken today, though this will result in little to no change in high temperatures today. NBM probabilities of high temperatures of 100 degrees are more are still upwards of 90% in the lower deserts, and changes of 90 degrees or more are around 70-90 percent across the Inland Empire. Through the weekend, an upper level trough essentially splitting into three waves will move inland across the Pac NW, Central California, and digging south well off the coast of Baja California.
1004 AM EDT Fri Apr 11 2025 High pressure will build across the region today through Saturday offering drier and cooler conditions.
/26/ (Friday through Saturday) A benign forecast continues through the short term period as high pressure remains dominate across the ArkLaTex vicinity.
ISOLATED STRONG TO SEVERE THUNDERSTORMS POSSIBLE THIS A cold front extending from Panama City to St Simons Island (as of 2 pm) will continue to trek southeastward into northeast flow over the next few hours. Despite somewhat limited deep moisture, instability will build amid steep mid level lapse rates and reach levels sufficient to support convective development beneath the deep and pivoting upper trough. Dry and cooler air behind the front will clear the skies through the predawn hours and lower temperatures into the upper 40s in SE GA and low/mid 50s in NE FL by daybreak Saturday. High pressure conditions will settle in over the forecast area this weekend bringing dry weather conditions, mostly clear skies, and initially breezy northwesterly winds.
120 PM EDT Fri Apr 11 2025 A low pressure system over eastern Virginia will bring showers and isolated thunderstorms to the area, before tracking northeast and off the coast Saturday. Clouds will begin to thin Saturday as high pressure builds in from the west.
* Brush by cold front brings light showers late tonight and breezy periods Saturday. * Fast moving upper wave and attendant cold front will bring isolated showers to NE Cal overnight into early Sat AM.
1217 PM CDT Fri Apr 11 2025 (Today through Saturday) A weak front north of the area will continue to drift south this morning and should get into at least the northern parts of our area shifting winds to the east or northeast, but other than that, the front will not be very noticeable as it will not come with any rain chance, and temperatures will not be much cooler than they have been. High temperatures this afternoon will range from the low and mid 90s west to the lower 80s along the coast. Expect high temperatures a few degrees warmer tomorrow. A backdoor cold front tries to approach from the northeast through the day Saturday, but most likely doesn't make it into the region.
A TEMPO line was added to show the window with the highest potential for showers/storms. This afternoon and evening, weather conditions will begin to deteriorate as upper level trough pushes over the region.
Once the front passes, cooler and drier air will advect into the area with a gusty northwesterly wind flow. Temperatures will reach the lower 80s on Saturday afternoon.
(Rest of today through Saturday) Cloudy skies continue across the area as an upper level impulse rounds the base of the trough.
1227 PM CDT Fri Apr 11 2025 (Today through Saturday Night) A weak cold front will move through Southeast Texas over the next few hours and is expected to push offshore this morning. While temperatures will still be similar to what has been observed the last few days, the lower dew points will make it feel noticeably drier. Saturday night's lows will be slightly warmer as temperatures dip into the 50s north of I-10 and in the 60s south of I-10.
248 PM EDT Fri Apr 11 2025 (This afternoon through Saturday) 500mb analysis shows an upper low across southwestern VA with a longwave through extending back towards the Lower Mississippi River Valley. The low center and trough will push eastward and offshore the east coast tonight. High pressure will build in from the northwest overnight and into tomorrow. The mid level low pressure center and trough are providing just enough lift for a widespread cu field and the showers.
- The weekend will be dry and warmer with temperatures rising into the 70s to low 80s. A long wave mid-upper level trough extending from southeastern Canada all the way into the eastern Gulf will drift eastward through the weekend.
Windy conditions will develop this weekend as high pressure slowly moves east of the state. High pressure is peaking over the region today before weakening slightly and shifting southeast as a trough moves by to our north this weekend. Though it will be just a couple degrees cooler on Saturday, this will still be in record territory for places like Prescott and Winslow and near-record at many other locations.
321 PM EDT Fri Apr 11 2025 High pressure will lead to dry conditions and moderating temperatures through the weekend.
138 PM EDT Fri Apr 11 2025 High pressure will build across the region today through Saturday offering drier and cooler conditions.
Clouds will start to increase ahead of an upper level trough which will drop into the region from the north. This upper level trough may also produce a few light rain showers this afternoon east of the Mississippi River.
The high pressure ridge responsible for the well above normal temperatures will shift east over the weekend bringing breezy conditions along with a few degrees of cooling.
150 PM MST Fri Apr 11 2025 Record breaking heat is likely today under a strong ridge of high pressure aloft. Strong high pressure has built over the region, with the upper level ridge axis basically directly over us today.

1236 PM CDT Fri Apr 11 2025 (Today through Saturday) A cold front is expected to continue sliding south through our area today, looking to be pushed through land areas by mid to late morning. Outside of that, afternoon high temperatures today will be just a touch, a couple degrees, cooler than yesterday. Winds will increase out of the north this afternoon following the cold front, with peak gusts around 20 to 25mph. Saturday will also see cooler MaxT's, low to mid 70s for all, with the cooler air from the front.
Global guidance continues to highlight a longwave upper level trough pattern continuing its eastward push towards the Atlantic coast. At the same time, a dry cold front over the Lower Tennessee Valley Region will track southward across our CWA later this evening. Expect overnight lows to drop into the low/mid 40s areawide.

205 PM CDT Fri Apr 11 2025 Forecast discussion for routine afternoon forecast issuance - Warm/dry weather continues on Saturday with high temperatures in the low 60s inland from Lake Michigan.
(This evening through Saturday Night) The upper level trough responsible for yesterday evening's frontal passage reaches the extent of its amplification along an axis running the length of the Appalachians tonight. From there, the trough lifts northeast towards New England, while a closed low develops as it moves off shore. This departure clears the way for the ridging which has remained over the Rocky Mountains for much of this week to press its own eastward advance, resulting in the ArkLaTex resuming its warming trend this weekend while skies remain mostly clear and weather conditions remain quiet. In truth, yesterday's surface boundary was only a cold front in the strictly academic sense, and today's high temperatures may well result in understandable questioning of whether such a front interacted with our area at all.
/NEW/ /Today and Tomorrow/ Yesterday's cold front has resulted in rather pleasant weather across North and Central Texas this afternoon. High temperatures are still 5-10 degrees above normal, in the low 80s for most, but nice enough to enjoy the evening outdoors. A high pressure ridge is moving across the I-35 corridor this afternoon and will build over the Eastern CONUS this weekend. Areas across West Texas and the Big Country will be exceptionally warm for this time of the year with highs peaking about 15 degrees above normal--in the low 90s.
Shower activity has remained abundant in the Straits of Florida and over the Lower Keys through today. Tomorrow, a cold front will move across Florida and through our area into tomorrow afternoon. This cold front is expected to be dry, therefore PoPs remain near nil as it passes through.
254 PM EDT Fri Apr 11 2025 - Major flooding continues on the lower White and lower East Fork White Rivers. - Significant river flooding continuing through at least the next 1 to 2 weeks in some spots on the lower White and lower Wabash. - Clear and Cold tonight with near to slightly below freezing lows.
(This evening through Saturday Night) Fair weather continues with a slightly warmer day and plenty of sunshine. Southerly surface winds will resume in the afternoon as the high shifts to our east. Highs will generally be in the low to mid 80s.
WESTERN RIVERSIDE AND SOUTHWESTERN SAN BERNARDINO Water vapor satellite imagery shows the thermal ridge axis has shifted over Arizona, allowing heights to slowly fall through the weekend.
(Through Saturday) Following frontal passage today, temperatures will dip overnight to the low 50s/high 40s across the region.
About 10 degrees cooler today and another 10 degrees Saturday as a Pacific upper trough replaces yesterday/s ridge. At 9AM MDT a surface cold front extended from northern ID through central OR to the northern CA coast then into the Pacific. Surface winds N-NW 5-10 kt today and increasing to 10-15 kt with gusts 20-30 kt possible along the cold front late tonight through Sat morning.
Tonight, an upper level ridge begins to move in from the west and NVA will result in dry conditions throughout the area.
1254 PM MDT Fri Apr 11 2025 - A cold front moving through this evening will bring a low (25-45%) chance for precipitation. - Cooler and active weather for the weekend, with a 70-90% chance of precipitation.
With one last chance for record heat Friday, our warm- up comes to an end Saturday as a upper trough pushes a cold front through the Silver state. This front will bring cooler temperatures, but little in the way off precipitation.
142 PM EDT Fri Apr 11 2025 Expect some showers behind a low pressure system passing to the south.
