234 AM CDT Sun Apr 24 2022 An upper level trough will exit the region today leaving cooler dry air behind it.
Light-moderate southwesterly flow aloft will persist across the TN Valley overnight, as a mid-level ridge remains centered off the coast of GA/SC. Across the remainder of the forecast area, a persistent SSE wind will result in sufficient mixing to keep temperatures a few degrees warmer and reduce the risk for fog development. Another warm day is on tap over the TN Valley on Sunday as the axis of an upper ridge continues to push eastward. This will lead to another mild night Sunday night, with lows in the lower 60s once again.
Favorable convergence on the lee of the Black Hills as the base of the H5 trough swings through the region. Given that the latest NAM and GFS are indicating low pressure deficits on the 285K to 300K surfaces with weak upglide until 21Z, snow will persist through at least this morning. This is where the coldest freezing temperatures will be from 20 to 25, with upper 20s across southeastern zones.
High pressure is starting to retreat to the east as a cold front slowly approaches Middle Tennessee from the west.
Currently, stacked low pressure centered over southeastern North Dakota early this morning, with widespread wrap around precipitation across western and central ND, in the form of snow west and a mix central. Still, with sfc temperatures in the low to mid 30s forecast today, once snow ends expect conditions to greatly improve as it will be hard to blow much snow around given that what is on the ground will be wet and heavy.
344 AM CDT Sun Apr 24 2022 Forecast discussion for routine morning forecast issuance Windy and mild today, then a return to cooler weather for the start of the work week. The evolving pattern will be less favorable for the passage of major troughs across the area, and will likely keep Gulf moisture south of the area.
441 AM CDT Sun Apr 24 2022 (Issued 438 AM CDT Sun Apr 24 2022) Today through Monday: A sfc cold front will slowly push eastward through the day today, clearing the area during the late afternoon hours. The front's slow progression eastward will also allow us to warm into the upper 60s to near 70 today as we'll have temperatures at 925mb lingering around 13 C and we'll have a chance to see sunshine this afternoon as the dry slot from the low pressure system to our northwest moves overhead. CAA will increase tonight following the front, and overnight lows should drop into the low 40s to upper 30s. Monday will be dry, but a secondary cold front will push through during the daytime hours, bringing a re-enforcing push of cold air on northwesterly winds.
952 AM EDT Sun Apr 24 2022 High pressure will prevail through Monday.
Nice weather continues today as high pressure builds with dry and mild conditions.
Today will be cooler and thanks to an increase in expected cloud cover farther south, have lowered highs slightly. Near critical fire weather conditions are possible across the entire area today with the lowest relative humidity expected mainly south of HWY 6 and the strongest winds expected north of I-80. Tonight will be rather chilly as lows dip into the lower 30s most places and even into the upper 20s for a few places out west. High pressure works its way in at the sfc and leads to lighter, more northerly winds.
517 AM EDT Sun Apr 24 2022 A slow-moving warm front over central Pennsylvania will trigger a few showers and thunderstorms this afternoon.
Convection will potentially last through the evening as the stationary boundary is expected to remain relatively in the same position before a cold front pushes it southeast. The cold front mentioned above will push into the region this afternoon, resulting in breezy northeasterly winds. A mid level low pressure trough will edge east early Monday with deep layer drying expected, and diminishing and ending shower chances in the southern Rolling Plains.
800 AM EDT Sun Apr 24 2022 High pressure will sit off the East Coast today through Monday and keep conditions generally dry. Moisture will gradually increase from the west late Monday through Monday night ahead of an approaching cold front.
637 AM CDT Sun Apr 24 2022 (Today and Tonight) A couple of semi-organized areas of thunderstorms are ongoing early this morning that are relevant to eastern Oklahoma and northwest Arkansas: the first being along the cold front situated just northwest of the forecast area in north central Oklahoma and southern Kansas and the second associated with the low level jet aligned just south of I-44.
A stacked, large, deep, but weakening storm system centered over MN early this morning will slowly drift northeast over southeast Canada during the short term period, and its trailing cold front will move into eastern KY from the northwest on Monday. On Monday, the system's upper trough will begin to move in from the west as the cold front enters the region, providing support for precip. The period begins with the forecast area being in the middle of cold frontal passage.
Look for high pressure to bring mainly sunny skies today and gradually warming temperatures.
Latest surface analysis is showing a cold front extending from a deep low over the northern Plains down through Iowa into western Missouri. The HREF is still showing that the cold front will slowly progress southeast across the CWA through this evening as the upper low moves from the northern Plains into southern Ontario. Cooler weather is expected today with the clouds, rain, and the front moving through the area. Britt Majority of ensemble members still agree that the upper low over the western Great Lakes will move off to the east at the same time a ridge will amplify over the central CONUS mid-late week.
Mid-upper level trough/low has slowed in eastward progression into the Upper Midwest, as system occludes with a cold front pushing through central Iowa. A pre-frontal trough extends into eastern Iowa. Key Messages: 1) Showers gradually tapering off 2) More wind 3) Not as warm with more seasonable temps Low level forcing ahead of cold front and pre-frontal trough and mid-level dCVA will shift gradually eastward taking the rain/ showers with it. One area of lower confidence on highs is across portions of east central/northeast IA where the delta could be warmer than forecast, as the deeper mixing RAP/NAM models to around 800 hPa if they verify CID north/west in abundant solar insolation could yield more widespread mid/upper 60s in this area.
Snow is light this morning and temperatures are rising above freezing. The low that has been affecting the area this weekend is currently spinning over far southeast ND. Gusty northwest winds are expected today behind this low. High pressure builds in tonight drawing in drier air. Relatively chilly temperatures are expected Monday night, with lows generally between 20 and 25 F (10 to 15 below normal), as high pressure noses in from the north.
618 AM EDT Sun Apr 24 2022 High pressure will remain in control through early this week.
Today, high pressure over CA/NV provides seasonable afternoon temperatures (upper 60s for lower valleys, 50s to around 60 for Sierra communities), sunny skies, and light winds. Monday, the next Pacific low pressure trough approaches the West Coast while high clouds spread across northern CA/NV. Breezy southwest winds develop Monday afternoon/early evening with peak gusts generally 20-30 mph, and afternoon temperatures will be a few degrees warmer than Sunday.
Wet weather will return Monday and before turning much cooler for the rest of the work week. as a high amplitude ridge over the region will help to supply us with sun filled skies and summery temperatures. Highs will be in the low to mid 80s across the majority of western New York. although it will be significantly cooler near the lakes where temperatures could be close to 50s and lower 60s. Max temps east of Lake Ontario will generally be in the lower 70s. but this low risk is probably not worth planning around.
The ridging in the mid and upper levels are slowly pushing east but likely remain an influencer of our weather here in Kentucky. A stacked, large, deep, but weakening storm system centered over MN early this morning will slowly drift northeast over southeast Canada during the short term period, and its trailing cold front will move into eastern KY from the northwest on Monday. On Monday, the system's upper trough will begin to move in from the west as the cold front enters the region, providing support for precip. The period begins with the forecast area being in the middle of cold frontal passage.
As this system exits, a ridge starts to build in today and winds turn downsloping across the western CWA. Some of the western mountains may have some isolated snow showers ahead of the approaching ridge, Sunday will be mainly dry and warmer across the west. Expect highs in the lower 50s for most, with some cooler temps in the 30s and lower 40s in the east where snow cover exists. Monday will be warmer as the ridge axis approaches, with highs in the upper 50s to lower 60s for most. Again, cooler in the east thanks to snow cover.
Afternoon highs will reach the low 80s along the coast and mid 80s inland.
1034 AM EDT Sun Apr 24 2022 High pressure will sit off the East Coast today through Monday and keep conditions generally dry. Moisture will gradually increase from the west late Monday through Monday night ahead of an approaching cold front.
Monday a dry cold front will bring cooler temperatures and cloudy skies.
Both surface and upper level ridging continue to weaken across the SE US ahead of an approaching frontal system. We have one more rain free day expected with mainly cirrus to note as the lower levels still need to recover some. There may be enough moisture return in the lower levels by late tonight for some patchy fog in the SW counties.
536 AM EDT Sun Apr 24 2022 Dry and warm conditions will continue before a cold front returns widespread rain chances on Monday, with cooler temperatures the remainder of the week. High pressure will maintain dry conditions with plenty of sunshine and well above normal temperatures today. Dry and warm conditions will continue overnight while increasing southwest flow behind the departing ridge results in increased cloud coverage towards morning. Shower and thunderstorms return on Monday with a cold front progged to cross late afternoon and during the night.
1011 AM EDT Sun Apr 24 2022 A stationary front will remain across our area through Monday, keeping cooler temperatures northeast, and warmer temperatures to the southwest.
The cold front that brought a few severe storms last evening has exited the forecast area. These will lead to a cooler day on Monday with highs in the mid 50s to lower 60s.
Mainly clear skies as northwest flow returns across the CWA as the upper level low to the north continues its eastward progression. A cold front has pushed through the CWA giving way to cooler temperatures overnight dropping into the mid 30s to mid 40s northwest to southeast. Afternoon high temperatures will be cooler as well ranging from the mid 60s to low 70s. Fire weather concerns will be diminished with the cooler temperatures as relative humidity values stay above 20-30 percent. The new work week starts off on the cooler than average side of things only in the 60s under the continued north winds.
714 AM EDT Sun Apr 24 2022 Dry and warm conditions will be interrupted by a Monday cold front, with rain and thunderstorms expected during the afternoon and evening. The center of an amplified ridge axis overhead will gradually shift ewd today in response to a digging trough centered near Hudson Bay in Canada. This will support another warm, dry day across the forecast area, with locations away from the terrain forecast to reach the low 80s. Conditions tonight should be rather tantamount to that of today, as intensifying swly flow behind that departing ridge promotes increased cloud coverage towards daybreak Monday. Shower and thunderstorms return on Monday with a cold front progged to cross late afternoon and during the night.
734 AM EDT Sun Apr 24 2022 High pressure will prevail through Monday.
This high pressure will ease today as it settles to the southeast.
The island chain continues to sit on the southern periphery of a sprawling area of high pressure, and the gradient remains tightened. Dewpoints are currently in the lower to mid 60s, as the aforementioned anticyclone continues to pump in air from higher latitudes. The Florida Keys will remain on the southern fringes of the expansive area of high pressure that currently encompasses a majority of the East Coast. As the ridge is slowly shoved to the east by an incoming trough, winds will taper off and dewpoints will begin to moderate as the source of the airmass changes.
the forecast area will be under the influence of a strong low pressure center moving northeast into northwest Minnesota overnight with continued northwest winds of 10 to 25 mph with some higher gusts. Low temperatures are expected to range from the lower 30s in far eastern Colorado the lower 40s in Hill City. High temperatures will be cooler with middle 50s to lower 60s in far eastern Colorado, lower to upper 60s elsewhere. some upper level ridging moves over the area during the night ahead of a low pressure system off the coast of the Pacific Northwest. High temperatures are forecast to range from the middle to upper 50s in far eastern to the lower 60s elsewhere.
Winds will be northerly behind a cold front around 15 to 20 kts through about 22Z. A broad, mid to upper level trough is sitting over the northern to central Rockies into the Great Plains. The base of the trough is running through the Desert Southwest into the FA. A closed low associated with this trough is spinning over the Dakotas.
526 AM EDT Sun Apr 24 2022 Canadian high pressure will then remain over the area through Monday.
(Issued 438 AM CDT Sun Apr 24 2022) Today through Monday: A sfc cold front will slowly push eastward through the day today, clearing the area during the late afternoon hours. The front's slow progression eastward will also allow us to warm into the upper 60s to near 70 today as we'll have temperatures at 925mb lingering around 13 C and we'll have a chance to see sunshine this afternoon as the dry slot from the low pressure system to our northwest moves overhead. CAA will increase tonight following the front, and overnight lows should drop into the low 40s to upper 30s. Monday will be dry, but a secondary cold front will push through during the daytime hours, bringing a re-enforcing push of cold air on northwesterly winds.
To the west, winter headlines have been canceled, the Lake Wind advisory has been expanded in coverage and extended in time until 8 PM this evening as gusty winds will remain possible at times as that low pressure system continues to lift northeast and eventually away from the region. Otherwise look for a warming trend over the next couple of days as high pressure settles in across the area. The dry spell may last a few days before ensembles continue to bring in another low pressure system for late in the week and the upcoming weekend. Conditions will gradually return to VFR over all terminals by late this morning or early afternoon while the low pressure system lifts off to the northeast.
Most recent water vapor shows the upper low centered over the eastern ND/SD border this morning. As we progress through this morning, the low lifts NE and precipitation will taper off from west to east for our region. High pressure builds into the area tonight through Monday, and the upper ridge builds over the rockies.
High pressure will build into the area through midweek.
607 AM CDT Sun Apr 24 2022 (Today and tonight) Early this morning, scattered showers and thunderstorms have developed along a stalled cold front across the Big Country. The aforementioned cold front will slowly move south across the area this afternoon and evening. This time frame is when the higher potential for locally heavy rainfall exists, especially for our southern and eastern counties.
Tonight, a cold front will edge into east AR, and through the remainder of the Midsouth on Monday.
A frontal system will move inland late tonight for a return to cooler and unsettled conditions for much of the week ahead.
449 AM CDT Sun Apr 24 2022 The low that has been affecting the area this weekend is currently spinning over far southeast ND. Gusty northwest winds are expected today behind this low. High pressure builds in tonight drawing in drier air. Relatively chilly temperatures are expected Monday night, with lows generally between 20 and 25 F (10 to 15 below normal), as high pressure noses in from the north.
A cold front will move across the region on Monday bringing showers and some thunderstorms. Highs will be in the lower to mid 80s. Surface cold front to approach the area tonight pushing into northwest Ohio by daybreak Monday. The cold front will push across the area on Monday. Warm readings in the east with highs in the lower 80s with cooler cooler readings in the far northwest, where highs only reach the lower and middle 60s. Showers are expected to be exiting east and decreasing in coverage Monday night while a cold front pushes through of the Ohio Valley. Cool, northwesterly flow will help temperatures drop into the 40s Monday night behind the front as high pressure builds in from the west.
817 AM EDT Sun Apr 24 2022 High pressure remains in control of the eastern US and will slowly slide southward through Monday.
628 AM CDT Sun Apr 24 2022 An upper level trough will exit the region today leaving cooler dry air behind it. Seasonal highs in the low 70s is expected today and below normal highs in the low to mid 60s are expected for Monday.
421 AM MDT Sun Apr 24 2022 Most recent water vapor shows the upper low centered over the eastern ND/SD border this morning. As we progress through this morning, the low lifts NE and precipitation will taper off from west to east for our region. High pressure builds into the area tonight through Monday, and the upper ridge builds over the rockies.
For tonight, the upper low moves east as a weak upper-level short- wave trough rotates through the CWA. At the surface, a ridge will move over the CWA by 12z, resulting in light winds and near- record low temperatures over western SD (and especially over snow- covered areas, and also where skies become clear).
This comes in association with an upper trough and cold front located across this region.
133 PM EDT Sun Apr 24 2022 High pressure will prevail through Monday.
1243 PM EDT Sun Apr 24 2022 High pressure will prevail through Monday.
(This evening through Monday) Early this afternoon, a cold front extended from near Wichita Falls, southwest to Abilene and then west to near Midland. The main challenge will be the potential for a few severe storms late this afternoon and evening, primarily along the cold front/dryline intersection. The main severe threat will be across western portions of the Concho Valley and northern Edwards Plateau through early evening, where a few discrete storms may develop near the dryline/cold front intersection, within a moderately unstable airmass. Temperatures will be much cooler behind the front tonight and Monday.
Upper ridge builds into the region tonight through Monday night for dry conditions across the entire forecast area.
307 PM EDT Sun Apr 24 2022 Warm and mainly dry today, then a cold front brings showers and a few thunderstorms to start the work week. High pressure brings dry, cooler weather mid to late week. But ridging and dry air have allowed it to stay dry across the area. Highs today will rise into the 80s to near 90 degrees across the lowlands, and 70s to low 80s in the mountains. While mainly dry weather is expected to persist through tonight, moisture begins to increase as upper ridging shifts east and a cold front approaches from the west.
Skies become mostly clear overnight and continued southerly surface flow underneath southwest flow aloft will keep temperatures mild, dropping only to the low 60s. Attention turns westward as a cold front approaches, and the tightening surface pressure gradient will keep winds overnight near 5-10 mph, which should keep fog at bay.
The cold front that brought a few severe storms last evening has exited the forecast area. This will lead to a cooler day on Monday with highs in the mid 50s to lower 60s.
116 PM EDT Sun Apr 24 2022 The summer like day rolls on with temperatures already in the lower 80s in a few spots. The ridging in the mid and upper levels are slowly pushing east but likely remain an influencer of our weather here in Kentucky. A stacked, large, deep, but weakening storm system centered over MN early this morning will slowly drift northeast over southeast Canada during the short term period, and its trailing cold front will move into eastern KY from the northwest on Monday. On Monday, the system's upper trough will begin to move in from the west as the cold front enters the region, providing support for precip. The period begins with the forecast area being in the middle of cold frontal passage.
250 PM MDT Sun Apr 24 2022 Strong winds have continued across portions of southeast Wyoming & the western Nebraska Panhandle this afternoon, mainly for the high plains courtesy of ample low-level mixing & a belt of stronger 700 to 800 mb flow around 40 to 50 kts. Still have a few lingering snow showers, mainly in the vicinity of the Snowy Range, but would expect this activity to dissipate by this evening as the trough axis continues to shift eastward.
Dry, mostly clear, and warm weather with a passing ridge will continue today and on Monday, with temperatures about 5-10 degrees above normal on Monday.
Could see a few severe thunderstorms across parts of far southeast OK south of the cold front where the highest instability will be located, with large hail and damaging winds being the main threat. (Monday through Sunday) The cold front will exit the forecast area late tonight, with post-frontal precipitation tapering off Monday morning across far southeast OK. Drier and cooler weather will prevail for a couple of days as surface ridging (and lighter winds) settle across the area.
High pressure continues to dominate this afternoon. A trough will move across the central CONUS tomorrow with an associated cold front stretched from the OH valley southwest into Texas. Lows tonight will fall into the lower 60s which is approximately 5 degrees or so above normal for this time of year.
203 PM MDT Sun Apr 24 2022 Mostly clear to partly cloudy conditions have taken over today, as we transitions from being under the influence of strong weather system, to that of an approaching upper level ridge.
The cold front has been south of the FA since early this morning and continues to slowly push southward across the Big Country into the Hill Country. We should start to see these storms push to the southeast by the evening as the cold front continues pushing southward. Scattered clouds will be possible through mid to late afternoon tomorrow as and upper trough passes through the region. Relatively benign weather is expected through much of the upcoming week as a broad upper ridge axis gradually builds and settles over the central US.
244 PM CDT Sun Apr 24 2022 The low pressure system will continue it's slow track northeast.
Cold temperatures aloft and the high sun angle is contributing to steep lapse rates. This all may yield convective snow and high snowfall rates in the higher terrain. A majority of the accumulating snow will focus over the central and southern mountains in Colorado right under the trough. With lows below freezing a Freeze Warning has been issued since vegetation may be susceptible to these temperatures. Tomorrow a ridge builds over the region therefore a warming trend will begin.
400 PM CDT Sun Apr 24 2022 Continue to see band of precipitation wrapping through the area as the main upper low is situated over northeast MN, and will continue to lift northeastward into Ontario tonight. As the low lifts northeastward, these areas of precipitation will diminish and move gradually lift northeastward out of the area as well. Another upper level wave will dig southward behind the main upper low Monday dropping through northern and eastern MN Monday into Monday night.
