410 AM EDT Sun Apr 4 2021 07z sfc analysis shows high pressure edging to the south of the area. This has kept the skies mostly clear overnight along with light winds supporting a rather large ridge to valley temperature difference. Readings vary from near 30 degrees in the most sheltered spots to the mid 40s on the ridges. Dewpoints, meanwhile, are generally around 30 in the valleys to the low 20s on the ridges. They all depict the waning influence of a departing deep eastern trough as flat ridging moves into the region today and tonight. Look for another rather large ridge to valley difference in temperatures tonight allowing for some spots of frost in the most sheltered locations.
454 AM EDT Sun Apr 4 2021 Dry weather and warmer weather is expected today under high pressure. A broad area of high pressure should maintain dry weather and mostly sunny skies today. Dry weather should continue tonight as the broad area of high pressure tracks east across the region. An upper low is progged to persist of the NE CONUS through mid week, as a weak ridge tracks across the Midwest.
Mostly dry conditions again today as high pressure across the southeast continues to migrate toward the region.
142 AM EDT Sun Apr 4 2021 High pressure will remain over the region through the first half of the upcoming week resulting in a warming trend.
Temperatures begin to warm back to normal with highs in the 70s and lows in the low to mid 40s Sunday night and upper 40s to low 50s Monday night.
On our marine district, winds are northeast to east at 20 to 25 knots, with the highest winds on the Straits. A large and sprawling area of high pressure centered over the Southeast United States, into the Western Atlantic Ocean and well into Texas will sag southward and decay over the next several days. Given the deep layered anticyclone, moisture will remain scant along with a decelerating northeast to east low level flow will ensure little if any measurable rainfall along the Florida Keys.
325 AM CDT Sun Apr 4 2021 An upper level ridge is building east over the region early this morning. Southwesterly winds will continue to usher warmer temperatures into the area today. Highs will generally warm into the middle to upper 70s today, with some locations in the lower 80s not out of the question across portions of central MO. Southwesterly winds around 10 to 15 mph with gusts up to around 20 mph will be possible today, with the higher gusts expected across southeastern Kansas and western Missouri. The upper level ridge will remain over the area early this week. A weak upper level disturbance will ride through the ridge on Monday.
Tonight Through Monday Strong high pressure located over the central and southern Rocky Mountain states is causing dry northwest flow aloft over the Natural State with weak southerly flow at the surface. Through the forecast period, the strong area of high pressure will slowly migrate eastward and break down. Fair, dry, and warmer conditions will continue over Arkansas while surface pressures weaken to our west. Highs Sunday afternoon will generally range from the mid 60s over the northern higher terrain to the lower 70s elsewhere.
Clouds will be on the increase tonight which should keep temperatures a few degrees warmer than last night, especially across the north. East or southeast winds will keep things a little cooler with a little higher humidity values across the Fox Valley east to the lake, but will still be at the elevated level due to the dry conditions.
159 AM EDT Sun Apr 4 2021 A weakening cold front located over the north shore of Lake Erie early this morning will slowly move southward through early afternoon. This boundary will wobble across the region through the middle of the week when a stronger area of low pressure begins to impact the region as it moves to the middle Mississippi River Valley. Weakening cold front located over the north shore of Lake Erie early this morning will slowly move southward through early afternoon. The lower 70's may occur across NW OH. Much of the short term period will be quiet with upper ridging and predominately northwesterly flow aloft.
335 AM CDT Sun Apr 4 2021 Analysis this morning shows clear sky conditions and seasonably cool temperatures across the area with the old continental high pressure anchored to our southeast in southern GA. A few of the typically colder valley locations could even reach freezing before daybreak, but this is expected to be limited in extent. Temperatures will warm further today as mild warm advection takes place in the low levels and sunshine continues to be abundant. Afternoon highs are expected to range from the mid 60s atop the cooler ridgetop locations in the east to the low 70s at many valley locations in west/central areas. As a result, temperatures are only expected to fall into the low/mid 40s by Monday morning at most locations.
Highs on Sunday will trend warmer in the lower to mid 70s inland and in the mid 60s to around 70 degrees near the immediate coast.
It will be a warm day across the area too, with highs climbing into mid to upper 70s, cooler across north- central Wisconsin where highs will mainly be in the 60s. Monday will feature a warm and noticeably more humid day across the area as low pressure moves into southern Minnesota, with a warm front situated over northern portions of the forecast area.
440 AM EDT Sun Apr 4 2021 W/NW flow aloft continues over the area this morning downstream of ridging over the central CONUS, while at the surface an area of high pressure over most of the eastern CONUS extends down into the peninsula. High pressure settles over the area favoring improving boating conditions as winds and seas continue to diminish and subside. High pressure settling over the region with periods of near to critical RH values during the afternoons through mid week for much of the area before more moist southerly flow develops late in the week as high pressure moves into the Atlantic and a frontal boundary approaches the region.
Upper level ridge that lead to near-record highs (and one record set) is breaking down with cloud cover decreasing this morning, then increasing overnight. It will also be windy with the cold front that arrives Mon, but local studay indicates it staying just below Advisory level (strong MSLP gradient and strong cold air advection, but 500mb and 700mb are actually fairly weak with the upper level jet not in the right place and even the strength of it is only 90KT).
Evening Update Another quiet night across the Mid-South with current temperatures in the low 50s. Current 3 PM temperatures are generally in the lower 60s.
The southerly flow will help boost highs into the lower 80s for Easter Sunday. Monday will be another warm day with highs in the lower 80s. By then, surface dewpoints could actually reach the lower and possibly even mid 50s, certainly the most humid air of the season so far.
350 AM EDT Sun Apr 4 2021 Dry, high pressure will prevail through mid week. A cold front will then approach the area near the end of the week. However, surface dewpoint temperatures seem to be running a few degrees warmer than previously expected. This will produce southwest low level winds, which will result in warmer temperatures for today/Easter Sunday. Expect highs to reach the lower 70s most areas, except cooler right near the coast as winds will become onshore as a seabreeze develops. Although winds will be light and skies mostly clear, the atmosphere will be warmer than the previous night, but still cook/below normal temperatures, in mid 40s well inland, and the upper 40s to lower 50s near the coast. A noticeable warming trend is expected as mid/upper lvl ridging broadens just west of the area and shifts eastward.
1155 PM MDT Sat Apr 3 2021 A strong ridge still in place will bring mostly clear skies this evening into tonight with temperatures cooling to the 40s.
127 AM EDT Sun Apr 4 2021 Even warmer temperatures expected the next couple of days, but no chance for rain until mid week. Approach of this trough will yield a much weaker pressure gradient tonight with an expected quick drop off in gusts early this evening with decoupling. Good deal of sun for Sunday with high temperatures into the low 70s. A weak embedded smaller scale wave could couple with better low level jet/low level moisture convergence forcing for some rain shower chances to persist as far east as far northern Indiana/southern Lower Michigan by Monday in vicinity of renewed low level trough development.
/issued 1015 PM CDT Sat Apr 3 2021/ Another quiet night across the Mid-South with current temperatures in the low 50s. Current 3 PM temperatures are generally in the lower 60s.
There is a notable ridge-valley temperature split, and KY Mesonet stations at relative lower elevations are reporting cooler temperatures in the mid 30s to lower 40s. Lower 50s are still occurring in the Louisville Metro with 54 at SDF (20 degrees warmer than the Harrison County KY Mesonet station).
After a cool start this morning, temperatures will rebound quickly with full April sunshine across the region under high pressure. High temperatures are expected to mostly range from the low to mid 70s.
Low temperatures will drop into the low 40s along the coast and in the upper 30s across our GA/AL counties. For Sunday, the warming trend continues with high temperatures climbing up into the low to mid 70s under mostly clear skies. The local region will reside on the backside of mid-upper level troughing with weak high pressure covering the southeast CONUS in the boundary layer.
1048 PM CDT Sat Apr 3 2021 The theme for the remainder of the weekend will be the continued dry weather along with moderating temperatures with a surface anticyclone anchored over the southeastern CONUS. Low temperatures tonight are expected to be about 5-10 degrees warmer than those observed early this morning.
A weak area of low pressure currently over the western end of Lake Ontario and the Niagara Peninsula will track east and dissipate into a trough over New England this morning. Ridging over the nations mid section will expand across the Upper Great Lakes today and tonight. After a dry day Monday a warm front embedded within northwest flow will nudge towards our region from the Central Great Lakes.
A few embedded thunderstorms will also be possible through the period, mostly elevated due to the lack of forcing and instability in the lower levels. Highs today will range from the 70s along the coast to the lower 80s out west. Highs on Monday will be a few degrees warmer and ranging from the mid 70s to the mid 80s.
For warm weather fans, today begins the journey to warmer temps for the remainder of the week, with today's highs reaching into the low 70s and tomorrow's getting into the mid to upper 70s.
430 AM MDT Sun Apr 4 2021 Water vapor places flat upper level ridge over the plains. With surface trof moving through western South Dakota winds will highly dependent on deep mixing. Cold front slides through the area Monday. South central South Dakota will see another day in the low 80s. with noticeably cooler conditions elsewhere.
A surface warm front approaching the Susq Valley early today will be followed by mainly clear skies through early this afternoon as an area of low pressure drifts southeast from upstate New York. West-northwest winds will freshen later this morning and gust into the low to mid 20 mph range through this afternoon. Mixing down ensemble mean 850mb temps of 2-5C support max temps ranging from the mid 50s over the highest terrain of northern PA and the Laurel Highlands, to the mid 60s in the valleys of Central and Southern Pa. A ridge of High pressure builds east into the area tonight with mainly clear to partly cloudy skies and low temps ranging from the low to mid 30s over the Northern and Western Mtns to the upper 30s in the Southern Valleys.
Another day of cool temps with afternoon highs in the low 70s along the coast and mid 70s inland.
High pressure over the Southeast U. , and increased ridging over the region from the west will provide quiet weather today and tonight. Temperatures tonight will be in the low to mid 30s for areas south of Lake Ontario, and in the upper 20s to low 30s for the North Country. There will be a weak mid-level ridge across the Great Lakes, placed between a pair of upper level lows near Hudson Bay and off the New England coast. Disturbances will track along a slow moving warm frontal boundary which will be located to our west.
524 AM MDT Sun Apr 4 2021 The longwave ridge that has brought the warm temperatures to our region will continue to flatten and shift east. For Monday, a tight Pacific trough will dig into northern portions of the Great Basin. This trough will be supported by a relatively weak jet streak but as it drops down, the pressure gradient does look to tighten across our area. Outside of the fire weather concerns, another warm day on tap as southwesterly flow keeps pumping in the warmer air.
/issued 422 AM CDT Sun Apr 4 2021/ Weak upper trough passing over the region kicked up some convection last evening but precipitation has moved out of the area as the trough slowly moves east. High pressure to the west will begin to build into the region Monday before the next upper trough coming ashore the NW coast tracks southward flattening out the ridge.
Temperatures and dewpoints will gradually warm in advance of a deep upper low dropping into the central plains.
After another chilly start this morning, temperatures will warm into the low to mid 70s across the interior and the upper 60s to around 70 at the beaches. Negatively-tilted troughing off the New England coast will generate a strengthening ocean storm off the Canadian Maritime region that will maintain a deep and dry northwesterly flow pattern over our region. Strong surface ridging centered directly over our area this morning will gradually weaken and will essentially remain in place over our area.
Analysis this morning shows clear sky conditions and seasonably cool temperatures across the area with the old continental high pressure anchored to our southeast in southern GA. A few of the typically colder valley locations could even reach freezing before daybreak, but this is expected to be limited in extent. Temperatures will warm further today as mild warm advection takes place in the low levels and sunshine continues to be abundant. Afternoon highs are expected to range from the mid 60s atop the cooler ridgetop locations in the east to the low 70s at many valley locations in west/central areas. As a result, temperatures are only expected to fall into the low/mid 40s by Monday morning at most locations.
557 AM CDT Sun Apr 4 2021 The warming trend will continue due to upper level ridging over the region along with persistent south-southwest winds.
One more day of dry and unseasonably warm weather is on tap for today across the region thanks to the recent broad ridge of high pressure along and to our south. That ridge of high pressure begins to break down ahead of an approaching cold front beginning later tonight from the west. By Monday morning, a few of those stronger rain showers are expected to reach the ground, focused along and behind the passage of the cold front as it moves through northeast Montana. The low pressure trough responsible for the cold front stretches out and weakens by Monday afternoon.
High temperatures will hop into the lower to mid 80s this afternoon under increasing southwesterly flow.
328 AM PDT Sun Apr 4 2021 Dry weather with temperatures trending cooler today and Monday, then trending warmer through the rest of the week. Upper ridge axis has moved over the intermountain west with SW flow aloft over Norcal. However, the cooler marine air has filled the Valley and won't be mixed out today due to the very strong inversion. Later in the day and into the evening, the satellite cloud forecast increases high cloudiness over most of our CWA except the far Nrn zones as moisture spreads NEwd ahead of the closed low near 35N/140W. Some consistency in the modeling for Mon as an upper low and trof over B. As the trof moves Ewd Tue and Wed short wave ridging builds back into Norcal with a warming trend.
Today Through Monday Night Early morning SFC obs show temps about 10 deg warmer or so early this Sun morning compared to Sat morning. Even warmer temps will be seen on Mon.
422 AM CDT Sun Apr 4 2021 Weak upper trough passing over the region kicked up some convection last evening but precipitation has moved out of the area as the trough slowly moves east. High pressure to the west will begin to build into the region Monday before the next upper trough coming ashore the NW coast tracks southward flattening out the ridge.
Clouds this morning will keep temperatures in the 50s to lower 60s, but breaks late afternoon will allow temperatures to rise into the lower 70s.
336 AM MDT Sun Apr 4 2021 H5 ridge continues to dominate the weather across the state today. Conditions finally change on Monday as a trough finally breaks down the ridge. This will begin to bring surface moisture northward into the region, along with cooler air aloft.
805 AM EDT Sun Apr 4 2021 Dry, high pressure will prevail through mid week. A cold front will then approach the area near the end of the week. This will produce southwest low level winds, which will result in warmer temperatures for today/Easter Sunday. Expect highs to reach the lower 70s most areas, except cooler right near the coast as winds will become onshore as a seabreeze develops. Although winds will be light and skies mostly clear, the atmosphere will be warmer than the previous night, but still cook/below normal temperatures, in mid 40s well inland, and the upper 40s to lower 50s near the coast. A noticeable warming trend is expected as mid/upper lvl ridging broadens just west of the area and shifts eastward.
The low level east to northeast flow around high pressure over the southeast U. /issued 440 AM EDT Sun Apr 4 2021/ W/NW flow aloft continues over the area this morning downstream of ridging over the central CONUS, while at the surface an area of high pressure over most of the eastern CONUS extends down into the peninsula. High pressure settles over the area favoring improving boating conditions as winds and seas continue to diminish and subside. High pressure settling over the region with periods of near to critical RH values during the afternoons through mid week for much of the area before more moist southerly flow develops late in the week as high pressure moves into the Atlantic and a frontal boundary approaches the region.
909 AM EDT Sun Apr 4 2021 Temperatures have warmed solidly above freezing everywhere this morning. 07z sfc analysis shows high pressure edging to the south of the area. This has kept the skies mostly clear overnight along with light winds supporting a rather large ridge to valley temperature difference. Readings vary from near 30 degrees in the most sheltered spots to the mid 40s on the ridges. Dewpoints, meanwhile, are generally around 30 in the valleys to the low 20s on the ridges. They all depict the waning influence of a departing deep eastern trough as flat ridging moves into the region today and tonight. Look for another rather large ridge to valley difference in temperatures tonight allowing for some spots of frost in the most sheltered locations.
Ahead of the trough, southeast winds ramp up as we mix out mid to late morning, sustained to 20 mph and gusts between 30-35 mph. BUFKIT soundings indicate some decent gust potential southwest in the wake of the trough, maybe not so much northwest. Potent S/WV moving across far south central Canada on Monday will drive a cold front into the Northern Plains, dropping temperatures and bringing another period of gusty northerly winds.
Minor ridging continues across the Plains this morning as a mid level trough moves across the Pacific.
412 AM CDT Sun Apr 4 2021 Weak low pressure will dominate the region today. Low pressure will continue to push east on Monday and become more well-defined. Strong caa will set up on the north to northwest side of the low with a 12C drop in H85 temps noticeable in the tight thermal packing. At the same time, the southerly winds ahead of the low will draw up some minimal moisture.
632 AM EDT Sun Apr 4 2021 Another dry and mostly sunny day today with highs in the low to mid 70s and light winds.
448 AM CDT Sun Apr 4 2021 The warming trend will continue due to upper level ridging over the region along with persistent south-southwest winds.
A weak area of low pressure currently over WNY will track southeast and dissipate into a trough over Southern New England today. High pressure over the Southeast U. , and increased ridging over the region from the west will provide quiet weather today and tonight. Temperatures tonight will be in the low to mid 30s for areas south of Lake Ontario, and in the upper 20s to low 30s for the North Country. There will be a weak mid-level ridge across the Great Lakes, placed between a pair of upper level lows near Hudson Bay and off the New England coast. Disturbances will track along a slow moving warm frontal boundary which will be located to our west.
601 AM CDT Sun Apr 4 2021 An upper level ridge is building east over the region early this morning. Southwesterly winds will continue to usher warmer temperatures into the area today. Highs will generally warm into the middle to upper 70s today, with some locations in the lower 80s not out of the question across portions of central MO. Southwesterly winds around 10 to 15 mph with gusts up to around 20 mph will be possible today, with the higher gusts expected across southeastern Kansas and western Missouri. The upper level ridge will remain over the area early this week. A weak upper level disturbance will ride through the ridge on Monday.
Negatively-tilted troughing off the New England coast will generate a strengthening ocean storm off the Canadian Maritime region that will maintain a deep and dry northwesterly flow pattern over our region. Strong surface ridging centered directly over our area this morning will gradually weaken and will essentially remain in place over our area.
902 AM CDT Sun Apr 4 2021 High pressure continues to control the weather conditions over much of the southeast. Temperatures are already running around 5 degrees warmer than yesterday. With little cloud cover expected through the day, highs should climb into the upper 60s/lower 70s today (maybe a tad higher in typically warmer locations). A very dry day on tap with relative humidity values likely dropping into the lower to mid 20 percent range near and east of the I-65 corridor. As a result, temperatures are only expected to fall into the low/mid 40s by Monday morning at most locations.
552 AM EDT Sun Apr 4 2021 Dry, high pressure will prevail through mid week. A cold front will then approach the area near the end of the week. However, surface dewpoint temperatures seem to be running a few degrees warmer than previously expected. This will produce southwest low level winds, which will result in warmer temperatures for today/Easter Sunday. Expect highs to reach the lower 70s most areas, except cooler right near the coast as winds will become onshore as a seabreeze develops. Although winds will be light and skies mostly clear, the atmosphere will be warmer than the previous night, but still cook/below normal temperatures, in mid 40s well inland, and the upper 40s to lower 50s near the coast. A noticeable warming trend is expected as mid/upper lvl ridging broadens just west of the area and shifts eastward.
623 AM CDT Sun Apr 4 2021 Weak low pressure will dominate the region today. Low pressure will continue to push east on Monday and become more well-defined. Strong caa will set up on the north to northwest side of the low with a 12C drop in H85 temps noticeable in the tight thermal packing. At the same time, the southerly winds ahead of the low will draw up some minimal moisture.
After temperatures bottoming out in the upper 60s, under partly cloudy skies, temperatures have climbed into the lower 70s across the island chain.
