In addition to the freezing temperatures, chilly temperatures that could promote frost formation are expected this morning along the Coos County Coast, and a frost advisory has been issued. We will remain under the influence of high pressure for most of the week. This pattern will repeat for most of the week with temperatures (both afternoon highs and morning lows) getting warmer each day.
429 AM CDT Wed Apr 17 2024 - Largely dry conditions today, with only a chance of showers after sunrise - Gusty west to southwest winds today around 25 to 35 mph - Widespread chances of showers and a few storms south return for Thursday - A few chilly nights are expected for Thursday night through the upcoming weekend, which will likely lead to our first frost/freeze headlines of the season A relatively quieter day is on tap weather-wise today, as the area of low pressure that brought widespread severe weather yesterday continues to lift northeastward. Temperatures will also be closer to seasonal averages, with highs in the lower 60s north to the upper 60s south.
Upper low pressure has moved into southwest Minnesota this morning with the surface reflection centered over north central Iowa. The wind could briefly approach wind advisory criteria in some areas but generally, northwest winds of 20-25 mph with gusts over 35 mph are expected before a default high pressure ridge arrives by this afternoon and relaxes the gradient. Cloud level steering will be from the west/northwest and add in some drying with the arrival of the ridge and the stratus should begin clearing over the west by mid to late morning and much of the rest of the area this afternoon. The low level jet and strong theta-e advection lifting into southern Iowa in addition to isentropic lift and overrunning further north, will lead to showers and thunderstorm development into southern Iowa.
This low is expected to continue to swing ENE past the Great Lakes into ERN Canada getting absorbed into the main parent low over C Canada by late Thu. Across C AL, we will have a zonal to WSW flow in the upper levels as the low progresses, with some perturbations traversing through this flow.
Scattered showers will continue area wide this afternoon into Thursday morning as the trough lingers.
A fairly strong cold front will track southward across the Oklahoma and Texas Panhandles late tonight and Thursday morning with much cooler temperatures anticipated behind the boundary. These temperatures will be around 15 to 25 degrees cooler than highs foreseen today.
728 AM EDT Wed Apr 17 2024 Dry high pressure will continue to ridge across the area through the rest of the week.
The drier/cooler air remains NW of the area. but chances for convection return to the forecast Thu afternoon/night as a cold front moves SE into the state.
The unsettled weather pattern will resume on Thursday as another low pressure system approaches the region.
(Today) A warm front will lift north across the area today.
Otherwise, one last system will move across the area Thursday night before cooler air and drier weather arrives for the weekend.
538 AM CDT Wed Apr 17 2024 (Today) A warm front will lift north across the area today.
Dry high pressure will continue to ridge across the area through the rest of the week.
Looking at the current water vapor imagery there is a weak cold front moving over our northern areas coming off an upper level low over northern Idaho. Thursday will be mostly dry with high pressure building in from the west.
644 AM EDT Wed Apr 17 2024 (Today and tonight) Upper ridge axis translates eastward towards the east coast while an upper low moves from the upper Midwest towards southern Canada. Highs today will range through the 80s and lows tonight will fall into the low 60s.
Scattered showers will continue area-wide this afternoon into Thursday morning as the trough lingers.
513 AM MDT Wed Apr 17 2024 - A digging trough will bring cooler and wetter weather today and Thursday. - Behind the storm, the cooler weather sticks around through the first part of the weekend.
545 AM MDT Wed Apr 17 2024 UPDATED AVIATION SECTION Areas of snow and gusty winds continue through this afternoon before incoming high pressure arrives later this afternoon and evening.
Coverage of showers and isolated storms has continued to slowly increase over the past hour, but overall updraft strengths continue to struggle as lapse rates remain on the lower side and convergence is rather weak. Otherwise, one last system will move across the area Thursday night before cooler air and drier weather arrives for the weekend.
Highs on Thursday across majority of mid state region will be squarely in the low to mid 80s with showers and thunderstorms once again moving in from the west as afternoon hours progress.
Sunny skies will help high temperatures get into the mid to upper 80s widespread, with areas across southwestern Oklahoma and western north Texas getting into the low 90s. A cold front will start to creep into far northwest Oklahoma by early Thursday morning.
Dry, tranquil weather with warming temperatures will continue into the latter half of this week as flat ridging builds into the region. Currently, WV imagery and objective analysis show a weak trough in place over the Southwest this morning with dry northwesterly flow aloft keeping skies mostly clear. This trough will continue to shift east out of the area through the day today allowing 500 mb heights to rise to around 582 dm as ridging builds into the region. This will lead to temperatures further warming up above normal today as lower desert highs climb into the low to mid 90s this afternoon. Temperatures through the rest of the week will be similar to today as flat ridging dominates. Troughing across the northern CONUS will act to suppress further amplification of the ridge that would allow for additional warming across our area.
Radar shows scattered convection developing from near LDM southwest across the lake near the warm front. HRRR soundings show a pronounced inversion near 900 mb with limited instability north of the warm front. Instability will ramp up later this morning, especially over the southern cwa behind the warm front. Tonight will be mostly dry as the upper trough moves east, but the next system developing in the mid Missouri Valley will already be taking aim on the Great Lakes, so cloudy skies are expected Thursday and an afternoon shower isn't out of the question as an upper low noses into the region.
617 AM CDT Wed Apr 17 2024 - Cooler temperatures today with a marginal risk for severe storms overnight tonight for southeast Nebraska. - Cooler temperatures continue through the weekend, with morning lows dropping below freezing in many areas.
Radar has shown some light pop- up showers to the south of the Lower Keys, but hi-res guidance indicates that these showers will stay south of the island chain, leaving us dry for the rest of the day. High pressure over the western North Atlantic will maintain moderate to fresh easterly breezes through the rest of today. High pressure slowly weakens late week and through the weekend while moving slightly further east into the western North Atlantic.
644 AM CDT Wed Apr 17 2024 - Largely dry conditions today, with only a chance of showers after sunrise - Gusty west to southwest winds today around 25 to 35 mph - Widespread chances of showers and a few storms south return for Thursday - A few chilly nights are expected for Thursday night through the upcoming weekend, which will likely lead to our first frost/freeze headlines of the season A relatively quieter day is on tap weather-wise today, as the area of low pressure that brought widespread severe weather yesterday continues to lift northeastward. Temperatures will also be closer to seasonal averages, with highs in the lower 60s north to the upper 60s south.
605 AM EDT Wed Apr 17 2024 Showers and thunderstorms possible today into tonight, with a cold front moving through tonight.
Afternoon highs look to reach 5-15 degrees above normal throughout the forecast period, so soak up the warmer weather! Mostly sunny conditions will prevail, outside of high clouds rolling in on Thursday.
Upper level ridge offshore today with dry northerly flow aloft. Dry upper level trough moving down the backside of the ridge over Western Washington late tonight into Thursday night.
642 AM CDT Wed Apr 17 2024 (Today through Thursday) Upper ridging continued across the Gulf of Mexico early this morning. The verification trend over the last couple days has been toward the warmer guidance, and see little reason to change that.
520 AM MDT Wed Apr 17 2024 - Breezy with rain showers today into this evening, snow showers over the higher elevations of northeast Wyoming and the Black Hills.
Breezy northerly winds are forecast for coastal areas through today as a high pressure builds into the region. High pressure remain across the area promoting quiet weather conditions. Latest GOES-West satellite imagery depicts high level moisture from the Pacific moving around the ridge and spreading high level clouds across the forecast area this morning. Coastal temperatures are expected to be 3 to 5 degrees warmer compared with yesterday reading, though breezy northerly winds redeveloping in the afternoon will keep the coast from warming much more than the low 60s. As result, interior temperatures are expected to rises into the lower 80s on Thursday. While, NBM indicates a high probability of coastal temperatures in the low 60s degrees by Thursday afternoon.
Partly cloudy skies are expected for the remainder of the day with high temperatures reaching the lower 80s for eastern areas and upper 80s across Southwest Florida. Some localized portions of SW FL may even hit the lower 90s. However, strong subsidence from ridging aloft will help keep rain changes to a minimum. Temperatures today and tomorrow could reach the upper 80s or even 90 across southwest FL, while East Coast temps range from the low-mid 80s.
However, strong subsidence from ridging aloft will help keep rain changes to a minimum. Temperatures today and tomorrow could reach the upper 80s or even 90 across southwest FL, while East Coast temps range from the low-mid 80s.
- Cooler temperatures return for the weekend. Midlevel ridging bring dry and clear skies back to the area. A strong midlevel push of cooler air from interior Canada strengthens cyclogenesis and frontogenesis enabling the low to deepen quickly. Mostly clear skies thanks to the previously mentioned midlevel ridging allows for fairly rapid surface cooling after sunset Wednesday. More widespread showers form on the cool side of the cold front; hopefully bringing some much needed rain to much of the region.
Winds will remain gusty behind last night's cold frontal passage, especially across the Snake Plain, which will add a chill to today's cooler temperatures.
(This evening through Thursday) Our stretch of very warm temperatures for the past six days is set to grind to a halt tomorrow following a rather strong cold front arriving in the morning. Meanwhile in the mid and upper levels, a sheared upper trough in westerly flow overhead will give way to zonal flow on Thursday.
1217 PM CDT Wed Apr 17 2024 (The rest of today ) Low clouds and patchy fog had developed this morning generally along and south of a warm front currently near the I-40 corridor.
1252 PM CDT Wed Apr 17 2024 - Largely dry conditions today, with only a chance of showers after sunrise - Gusty west to southwest winds today around 25 to 35 mph - Widespread chances of showers and a few storms south return for Thursday - A few chilly nights are expected for Thursday night through the upcoming weekend, which will likely lead to our first frost/freeze headlines of the season A relatively quieter day is on tap weather-wise today, as the area of low pressure that brought widespread severe weather yesterday continues to lift northeastward. Temperatures will also be closer to seasonal averages, with highs in the lower 60s north to the upper 60s south.
323 PM EDT Wed Apr 17 2024 Rain showers are expected through most of Thursday, before high pressure briefly moves in for Thursday night.
249 PM EDT Wed Apr 17 2024 A stationary front will slowly lift northward as a warm front tonight, eventually pulling north of the region by early Thursday.
(Tonight through Thursday night) The biggest story for the short term forecast period will be the above normal temperatures that will affect Deep South Texas and the Lower Rio Grande Valley. A mid-level ridge will continue to influence the region. While some tiny showers and thunderstorms did get going this morning in the Lower Rio Grande Valley, SPC does have the far western parts of Starr and Zapata in a general thunderstorm outlook. However both PoPs and QPF remain very low for going into tomorrow and the mid-level ridge still has some influence over the region that will hinder the development of showers and thunderstorms.
1122 AM MDT Wed Apr 17 2024 - A digging trough will bring cooler and wetter weather today and Thursday. - Behind the storm, the cooler weather sticks around through the first part of the weekend.
The cold front will have moved through the area at the start of the near term period, heralding in a ~10 degree drop in Tds. Overnight lows drop to the low 50s. Right now, high temperatures in the low 80s along the Ohio River and highs in the mid 70s across central Ohio.
* Subtle dry, cold front passes through the Great Basin through this evening. Gusty ridge winds peaked earlier today with a downward trend forecast through the evening as the winds shift to the east tonight into early Thursday morning.
1149 AM EDT Wed Apr 17 2024 High pressure crosses the region today through Thursday.
pdf Dry weather and initially clear to partly cloudy skies will continue through the afternoon with cloud cover increasing tonight as high pressure ridging moves southward and prevailing flow shifts to become more out of the west. Overnight low temperatures will drop down into the upper lower to mid 60s for most inland areas and in the mid to upper 60s along the shoreline.
1241 PM CDT Wed Apr 17 2024 - Cooler temperatures today with a marginal risk for severe storms overnight tonight for southeast Nebraska. - Cooler temperatures continue through the weekend, with morning lows dropping below freezing in many areas.
342 PM CDT Wed Apr 17 2024 *Precipitation chances today and tonight *Strong winds this evening into the overnight *Cooler through the first part of the weekend *Another chance for rain/snow Thu. As for snowfall potential, did decrease precipitation chances across the northern Sandhills after midnight across the northwest Sandhills, which looks to confine most of the precipitation across the northwest Sandhills to rain as temperatures will generally main above freezing during the best chance for precipitation, however a brief period of a rain/snow mix can't be ruled out, but do not expect any snowfall accumulations. Cooler temperatures tonight and Thursday, weak CAA behind the frontal boundary will bring in lows tonight in the upper 20s to mid 30s and keep highs on Thursday generally in the upper 40s to low 50s.
1256 PM CDT Wed Apr 17 2024 - More rain today as a low pressure system moves from southern MN into central WI today.
Can't rule out an orographic precipitation band developing off the Crazy/Belts/Snowy mountains extending southeast over the lower elevations. Precipitation accumulations will be light as the northwest winds will dry out the lower elevations tomorrow, with afternoon RH values in the 20s in many locations.
1246 PM EDT Wed Apr 17 2024 Showers and thunderstorms possible today into tonight, with a cold front moving through tonight.
There is potential for highs to reach the upper 80s or even 90 across southwest Florida, with east coast temperatures in the low to mid 80s.
Thunderstorms will return to the Midsouth on Thursday afternoon and evening, ahead of a deep low pressure system lifting into the mid-Mississippi River Valley.
436 PM EDT Wed Apr 17 2024 - A dying cold front move into the area tonight and could bring a few showers/thunderstorms to our northeastern counties.
327 PM CDT Wed Apr 17 2024 Tonight and Thursday: Continued warmer than normal through Thursday. Surface analysis also showed a ridge along the Gulf coast states from the east. This ridge will remain in place through Thursday and help a warm moist airmass spread back across the whole CWA. This moist airmass will destabilize with daytime heating Thursday and there will be the development of isolated to scatted showers and thunderstorms but the potential for any severe storms looks to hold off until Thursday evening ahead of a cold front that will be approaching our western zones.
There's a moderate to high probability (50-90% chance) for heat index values to climb into the low 100s across western portions of the CWA today and tomorrow. Overnight lows will be in the low to mid 70s across the region.
(The rest of today ) Low clouds and patchy fog had developed this morning generally along and south of a warm front currently near the I-40 corridor.
1122 AM MDT Wed Apr 17 2024 - Breezy with rain showers today into this evening, snow showers over the higher elevations of northeast Wyoming and the Black Hills.
The upper trough over the Midwest will move off to southern Canada, and the jet stream helping power today's rain will move south of us tonight. The movement of these features allows for a mid level ridge to build in over us for Thursday. Clearing skies and building heights will allow for temperatures to rebound tomorrow, with valley temperatures in the low 80s for most of the region.
1238 PM EDT Wed Apr 17 2024 High pressure crosses the region today through Thursday.
By late week, there will be some flattening of the ridge as a large upper level low drifts across northern Ontario and our flow aloft will transition from northwesterly to more of a westerly (zonal) orientation for the upcoming weekend.
243 PM CDT Wed Apr 17 2024 - Severe thunderstorms may develop along a cold front late tonight and Thursday morning.
Warm and dry conditions are being observed across the area, thanks to upper level ridging. These temperatures are trending approximately 2 to 8 degrees warmer than this time yesterday afternoon. Locally breezy northerly winds are being observed mainly in the northern and central Sacrameno Valley as a trough exits the Pacific Northwest. Upper level ridging will continue to be the main synoptic feature the rest of this week, bringing a slight day to day warming trend and above normal daytime high temperatures.
(This evening through Thursday night) A weak upper level low is currently moving through the Great Lakes this afternoon. Going into tomorrow, a stronger upper level trough will push south out of Canada and into the High Plains to upper Mississippi River Valley.
A low pressure system tracking through the Great Lakes will push a cold front through the region this weekend. Diffuse boundary (warm front) over the forecast area has pretty much lost its identity. Better support for thunderstorms will be in the Ohio Valley and Great Lakes closer to the upper trough which is forecast to move across the Great Lakes this afternoon.
333 PM EDT Wed Apr 17 2024 - Dry tonight and cooler.
Have updated the near term forecast to expand fog potential and include a limited dense fog threat in the hazard graphics for early Thursday morning over the lower Pine Belt region. /EC/ Tonight and Thursday: Continued warmer than normal through Thursday. Surface analysis also showed a ridge along the Gulf coast states from the east. This ridge will remain in place through Thursday and help a warm moist airmass spread back across the whole CWA. This moist airmass will destabilize with daytime heating Thursday and there will be the development of isolated to scatted showers and thunderstorms but the potential for any severe storms looks to hold off until Thursday evening ahead of a cold front that will be approaching our western zones.
935 PM EDT Wed Apr 17 2024 A stationary front will slowly lift northward as a warm front tonight, eventually pulling north of the region by early Thursday.
Mostly clear, dry, and warmer than normal conditions are forecast Thursday into the weekend.
945 PM CDT Wed Apr 17 2024 Mid and high clouds are a plenty this evening as the subtropical jet persists ahead of deep troughing aloft nearing Srn Baja, with these elevated cigs quite thick on the evening satellite imagery from Cntrl/S TX E along the Gulf Coast states.
641 PM EDT Wed Apr 17 2024 - Dry tonight and cooler.
High pressure continues to build into the region. A high pressure ridge continues to build into Northwest California, promoting calm weather conditions. Latest GOES-West satellite imagery depicts high level moisture from the central Pacific moving around the ridge and spreading high level clouds across the forecast area; most of the high clouds are moving over Mendocino and Lake counties this afternoon. Coastal temperatures are expected to be slightly warmer compared with yesterday's reading, though breezy northerly winds have redeveloped this afternoon keeping the coast from warming much more than the upper 50s to low 60s. NBM, also, indicates a high probability of coastal temperatures in the low 60s by tomorrow afternoon.
307 PM MDT Wed Apr 17 2024 - Breezy with a cold front and possible showers in the evening.
While boundary level moisture is high (dewpoints in the mid to upper 60s) and supports fog development, the presence of the high level clouds will likely preclude fog from becoming too widespread or dense. As such, we may see temperatures a degree or two warmer on Thursday than today, with more widespread low to mid 80s possible than today.
733 PM CDT Wed Apr 17 2024 Tonight and Thursday: Continued warmer than normal through Thursday. Surface analysis also showed a ridge along the Gulf coast states from the east. This ridge will remain in place through Thursday and help a warm moist airmass spread back across the whole CWA. This moist airmass will destabilize with daytime heating Thursday and there will be the development of isolated to scatted showers and thunderstorms but the potential for any severe storms looks to hold off until Thursday evening ahead of a cold front that will be approaching our western zones.
742 PM EDT Tue May 14 2024 Eastward exiting low pressure will continue to provide some shower and thunderstorm activity on Wednesday, generally southeast of I-71.
Discussion: The upper low axis will be centered over us this morning as it continues to move eastward. Two areas of low pressure exist; one over the VA coast and the other over KY. Flow is expected to become westerly to northwesterly with the passage of the upper low, so upslope enhancement will be an additional forcing mechanism across the terrain.
(Today and tonight) High pressure over the northeast Pacific will nudge a bit closer to the Bay Area and Central Coast as low pressure aloft weakens over northern Baja. With slightly greater influence from the ridge expect the top of the marine temperature inversion to either hold steady or compress a bit over the next 24 hours. Lows will be mostly in the lower to mid 50s.
Patchy fog will be possible, most probable across Inland Southeast Texas and Central Louisiana where the calm winds and cooler temperatures & dewpoints likely to meet allowing for the fog.
224 AM MDT Wed May 15 2024 - Cooler today, with some scattered afternoon thunderstorms, and local redevelopment of showers in the evening.
Forecast min temps already have a good handle on this with overnight lows ranging in the middle 50s across our northern zones to the lower 60s near the I-20 Corridor and points south. 13 (This evening through Wednesday Night) A welcome reprieve from rain will continue through this short-term period as an upper-level trough slowly ejects eastward from the Mid-MS Valley. Likewise, look for wind speeds to drop off rapidly as well as high pressure builds firmly into the region. High pressure will maintain dry and increasingly warmer conditions on Wednesday with winds eventually trending back S/SW throughout the day. As light southerly flow persists on Wednesday night, overnight temperatures will run several degrees warmer compared to tonight with cloud cover also returning across our western half.
