1228 PM EDT Wed May 10 2023 High pressure brings dry, seasonable weather today and Thursday. Quiet weather in the near term period with high pressure and dry air mass in control. Otherwise, much of Thursday will remain dry, although a slight chance for showers and storms will be possible across extreme western/southern zones as a warm frontal boundary starts to lift north towards the area. Dry and increasingly warm conditions continue for the most areas Thursday as a high pressure remains in control. Models indicate a weak H500 wave moving from the southwest within a weak ridge.
(This evening through Thursday Night) Multiple bands of more intense convection are quickly developing and moving northward across the area in association with a slow-moving upper trough over East Texas. The upper trough will continue to slowly move north- northeast into the Ozarks on Thursday.
This activity is due to the combination of diurnal heating and the approaching warm front positioned across northeast AR and west TN. The warm front will lift northward through the region throughout the day, generating scattered to numerous showers and thunderstorm, with the greatest coverage during peak heating hours in the afternoon. Thursday night, shower and thunderstorm coverage will become more focused across the EVV Tri-State area, which will be closest to the warm front.
316 PM EDT Wed May 10 2023 High pressure will continue to bring dry weather and seasonable temperatures to the region through the end of the weekend. Big bubble, no trouble! High pressure will remain over the region throughout the period.
133 PM EDT Wed May 10 2023 Quiet weather will persist over the next several days with high pressure in control.
227 PM MDT Wed May 10 2023 There is currently a low pressure centered over AZ, and it will continue to progress eastward this evening and overnight. These showers will stick around overnight as the low tracks over the area. Current obs show rather dry air in the low levels so lower elevations may struggle and saturation could take some time.
*Greater severe threat tomorrow late afternoon through the evening as a low pressure system moves through and an arc of storms forms.
A weak area of low pressure in the mid-levels will translate up the Mississippi valley throughout Thursday. Discussion: We begin the period Thursday night with high pressure just off to our southeast. Meanwhile, an area of low pressure will be centered across the Great Plains with an associated warm front extending across to Western TN.
A weak wave ejecting off the main low pressure system to our south will allow for development of showers and thunderstorms further south of I-90 and eventually will track to the north. Thursday the low will be spinning in central Montana and wrap around showers will move west across the Continental Divide.
Shutdown city across the Florida Keys, highlighting the value of this morning's KKEY RAOB which showed significant inhibition and dry air in the lower levels. Temperatures are nearing 90 in a few locations with dewpoints in the lower 70s. A negatively tilted long wave trough axis composed of two short waves, one near the Four Corners and the other near the Texas Gulf Coast, will bifurcate tonight through Thursday night. The southern piece of energy will nestle beneath a building mid to upper- level ridge over the South, effectively creating a mini Rex-block. Meanwhile, the SFC anticyclone centered near the Delmarva will slide southeast into the western North Atlantic and transition into a burgeoning subtropical ridge.
High pressure anchored over the eastern Great Lakes will continue to control the weather across central Illinois tonight.
High pressure anchored over the eastern Great Lakes continues to dominate the weather across central Illinois this morning. With mixing up to about 830mb, afternoon high temperatures will be a couple of degrees warmer than yesterday in the upper 70s to around 80 degrees. Barnes A high pressure system is sitting over the Great Lakes today, which is providing us the beautiful weather that is on deck for today. Delaney On Thursday, the high pressure system that is over the Great Lakes will move off to the east and moisture advection will increase, bringing higher dew points back into the Illinois area.
Central Indiana was enjoying sunny skies and mild temperatures this afternoon thanks to high pressure at the surface and some ridging aloft. The lower atmosphere will remain dry with a light east to southeast flow. The clouds will help keep temperatures warmer than last night, but feel that blended guidance is overdoing how much this will occur. Lows will be in the lower to middle 50s most areas. Widespread showers with some embedded convection will begin to overspread the area Thursday night as a warm front lifts north.
Clouds thicken and lower on Thursday as return flow sets up, with some weak isentropic lift as it rides up and over a warm front draped across the Tennessee Valley.
1235 PM CDT Wed May 10 2023 (Today through Thursday) Rain and thunderstorm chances will continue today as moisture continues to move around an area of low pressure to the north of us. Precipitation will begin to taper off this afternoon as the low moves to the northeast and a weak ridge will build in over the area.
1218 PM CDT Wed May 10 2023 (The rest of today and tonight) Showers and scattered thunderstorms will overspread eastern Oklahoma and northwest Arkansas later today and continue into tonight in association with an upper level low in Texas that will lift to the north-northeast across the region tonight.
Forecast is in great shape this morning as high pressure provides quiet conditions across central Indiana. Ridging at the surface and aloft will lead to continued mostly clear skies, dry weather, and mild temperatures through tonight. Will increase diurnal temperature range a bit, primarily on the min temp side, as the aforementioned decoupling should allow for very effective radiational cooling and bring lows to the lower side of the guidance envelope. Thursday: Amplifying mid-upper ridge and positive 500-mb height anomalies are present.
Upper low over TX and W Gulf this afternoon to open and impinge on Eastern U. upper ridging with moderate vort maxes approaching FL Thursday afternoon.
255 PM EDT Wed May 10 2023 High pressure will provide warm, dry, and mostly sunny weather through the end of the week.
1153 AM EDT Wed May 10 2023 High pressure brings dry, seasonable weather today and Thursday. Upper level ridging slowly shifts east with the region in northwesterly flow aloft through the period. At the surface, high pressure over the Lower Great Lakes yields weak but dry northerly flow through the day. Dry and increasingly warm conditions continue for the most areas Thursday as a high pressure remains in control. Models indicate a weak H500 wave moving from the southwest within a weak ridge.
(The rest of today and tonight) Showers and scattered thunderstorms will overspread eastern Oklahoma and northwest Arkansas later today and continue into tonight in association with an upper level low in Texas that will lift to the north-northeast across the region tonight.
1102 AM EDT Wed May 10 2023 High pressure will promote mostly dry weather with a warming trend through the second half of the week. Calm and quiet weather prevails through the afternoon with high pressure centered over eastern OH and western PA. Temperatures aloft are warmer than yesterday, which will translate to highs this afternoon in the mid 60s to low 70s. Pleasant and warmer weather Thursday with broad anticyclonic flow across the eastern conus. Highs will top out in the low to mid 70s for most. Cooler in the 60s along the Lake Erie shoreline, and east of Lake Ontario from the east and southeastern shores to the Black River Valley, and across the Watertown Metro. as a negatively tilted mid level ridge will largely remain centered over the Ohio valley and Upper Mississippi valley.
A fast-moving low pressure system will deliver cooler and windy conditions today, along with a chance for a few rain and high elevation snow showers. A compact upper low over the Imperial Sand Dunes this morning will move into central Arizona later this morning and into New Mexico this evening. The low will be filling as it moves into our area, but enough cold air and mid-level instability exists for scattered rain and high elevation snow showers. Southwest gradients ahead of the low have already produced strong winds at KIPL/KYUM this morning and these gradients will shift east through the day, with the strongest winds in our eastern CWA by the afternoon.
339 PM EDT Wed May 10 2023 Quiet weather will persist over the next several days with high pressure in control.
(Through Tonight) A cold front is slowly approaching from the north, bringing ample moisture for thunderstorm development along the sea breeze boundaries.
An upper level trough ejecting out of the Rockies and into the central Plains, will dictate the weather pattern across the region through the end of the week and into the weekend. Cluster analysis is in good agreement on the overall progression of this feature into the Plains, with only minor discrepancies regarding the strength of the troughing.
449 PM EDT Wed May 10 2023 High pressure continues to remain over the area and courtesy of that dome of high pressure; clear skies exist and temperatures have climbed into the upper-70s.

219 PM EDT Wed May 10 2023 High pressure brings dry, seasonable weather today and Thursday. Quiet weather in the near term period with high pressure and dry air mass in control. Otherwise, much of Thursday will remain dry, although a slight chance for showers and storms will be possible across extreme western/southern zones as a warm frontal boundary starts to lift north towards the area. A warm front continues to drift into our southwestern zones Thursday night before losing gumption with the loss of daytime heating.
157 PM MDT Wed May 10 2023 The active weather pattern is starting to ramp up currently, as the trough settles across the Four Corners region. Morning sounding showed directional shear across the lowest 10000 feet, and inverted-V sfc profile. After this wave moves through, models continue to move the main H5 trough norther across Colorado. This lowers steering flow across northern and western Wyoming to almost nothing, so any storms that have formed will possibly slow and meander through the evening and early overnight.
127 PM EDT Wed May 10 2023 High pressure over the southern Great Lakes will move slowly east through the next day or so, with dry and sunny conditions expected.
109 PM EDT Wed May 10 2023 VFR conditions continue through the period with light winds generally out of the west/southwest as the center of high pressure drifts southeast of the region. Upper level ridging over the Plains continues amplifying in response to an upstream trough digging into the Front Range which maintains persistent height rises over SE MI through Thursday.
1240 PM CDT Wed May 10 2023 (Today through Thursday Night) A mid/upper low over central Texas will slowly meander northward today. The environment to the east of the low features ample lift and PWAT along with some modest instability. It just so happens that southeast Texas is located within this environment east of the low. Shower and thunderstorm activity is expected to become more isolated during the afternoon hours as the low pulls away.
256 PM CDT Wed May 10 2023 Aside from a few light showers along and west of the James River this morning, have seen largely quiet conditions prevail across the region as an upper level trough deepens across the southwestern CONUS. By Thursday morning, models show an upper level low becoming cut-off as it moves over the Rockies. Should see coverage increase heading into the afternoon/evening, especially along and west of I-29 as the aforementioned upper level low edges closer to the region.
134 PM EDT Wed May 10 2023 Aviation -- Warm and Dry Through Thursday -- Increasingly warm yet still rather dry air will be slowly flowing in on the back side of high pressure today and Thursday.

Evening surface map indicated 1020 mb high pressure over the eastern Great Lakes, with low pressure along the lee of the Rockies. Aloft, a vigorous upper low was noted over the 4-corners, with a weaker mid level circulation over northeast TX. Rain is as close as southern MO but won't make much progress northeast overnight due to the slow movement of the low and dry low/mid levels ahead of it. 25 High pressure anchored over the eastern Great Lakes will continue to control the weather across central Illinois tonight.
Showers and isolated thunderstorms are expected to dissipate this evening as an upper-level trough exits the region. High pressure builds over the region for the later part of the week bringing increasing temperatures and dry conditions to central and northeastern Nevada. Dry conditions and partly cloudy skies are expected Thursday as ridging begins to build over the region. Lows tonight primarily in the 30s will be a few degrees warmer Thursday night where 40s begin to show up across the lower valleys to the west and south.

Once lake breeze showers diminish after sunset, expecting quieter weather for the overnight period as the UP faces zonal flow aloft at the top of a ridge. Upper air pattern consists of a 500 mb trough and closed low over the Rockies and a ridge over the northern plains into the upper Great Lakes 00z Fri. The closed low moves to the northern plains 12z Sat and then gets absorbed into a trough in the northeastern U. In the extended, the GFS and ECMWF show a 500 mb trough over the northeastern U. with a ridge in Alberta and British Columbia and a closed low over the swrn U. There is also an upper level ridge over the sern U. Pattern changes little 12z Mon except that the ridge becomes stronger in western North America while the trough amplifies in the northeastern U.
Early this morning, a negatively tilted trough was moving out of the Four Corners region and into the Southern Plains, with a closed low over northeast New Mexico, and southerly flow over the Dakotas.
1117 PM EDT Wed May 10 2023 High pressure will provide warm, dry, and mostly sunny weather through the end of the week.
Closer to Lake Michigan, high pressure will continue to influence the wind pattern. There remains uncertainty amongst the high- res guidance regarding the coverage of this initial activity and how far north it gets due to the drier air that needs to be overcome.
Area of high pressure over the region remains in control while upper level low approaches from the west. In addition, the delay in the sea breeze, will also allow temperatures to climb up into the low to mid 90s during this time.
