832 PM EDT Mon Oct 9 2017 Moisture with the remnants of Nate will continue to shift off to the east as high pressure builds overhead. Tuesday should be mostly dry with high pressure in place but clouds will start to spread northward ahead of the next low pressure system, ejecting out of the midwest. This aforementioned low will track across northern Ohio, with the warm front providing for increased rain chances overnight Tuesday. It appears both downsloping southeasterly wind and a dry slot may be limiting factors for QPF outside of the initial warm front surge, but will still maintain likely PoPs, even with low QPF forecast.
1016 PM EDT Mon Oct 9 2017 High pressure will ridge southeast into the region from the Upper Great Lake tonight and Tuesday.
Temperatures are currently in the low 80s with dewpoints around 70.
This lift wl be spreading into an area that will be experiencing a period of short wave ridging so clouds may thin as they progress eastward and expect any -shra to remain to the north and west. Diurnal cumulus should diminish by early evening as well, nearby sagging cold front.
755 PM MST Mon Oct 9 2017 Breezy conditions and cooler temperatures will continue to affect the region tonight in the wake of a cold front. Weak high pressure will return to the region over the next couple days allowing high temperatures to climb back several degrees above the seasonal average. Low pressure and an associated cold front have cleared all but far SE Arizona this evening with robust sfc pressure rises over northern Arizona creating a steep gradient along the northern edge of the forecast area. Exposed areas through central AZ (ridge tops, etc. /219 PM MST Mon Oct 9 2017/ High pressure setting up across the Four Corners overnight will promote an early onset of the northeasterly downslope flow across central Arizona this evening.
A cold front will be moving southward across the state tonight with low clouds and patchy fog possible ahead of the front. The corresponding cold front is expected to move across the CWA/MSA Tuesday.
715 PM EDT Mon Oct 9 2017 High pressure will nose in from the Upper Great Lakes tonight.
1022 PM CDT Mon Oct 9 2017 The evening sfc analysis indicated a cold front extending from near a TUL, to just E of MLC, to TKI, to ACT and just SE of a LZZ line as of 03Z, with the sct convection that had developed earlier this evening continuing to diminish due to the loss of SBCapes/a narrow instability axis over Ern OK and Ecntrl TX. /issued 713 PM CDT Mon Oct 9 2017/ For the ArkLaTex, KTYR/KGGG and KELD/KMLU may see some convection with better moisture as cold front arrives overnight/early Tues.
A few isolated showers/storms remain present across SW Georgia and the eastern FL Big Bend, but otherwise dry conditions are expected tonight as instability decreases and an upper level ridge remains in place over our area.
With some passing cloud cover, overnight temperatures tonight will be warmer than what was observed this morning, but otherwise conditions will be dry.
Near and south of the front, temperatures reached the low 80s around Macomb.
749 PM EDT Mon Oct 9 2017 Ridge of high pressure developing over the area will keep southerly flow and chances of showers and thunderstorms in place through the middle of the week.
804 PM EDT Mon Oct 9 2017 A front slowly crosses midweek, then dry and warm high pressure dominates last half of the week.
12Z models are in general agreement that this frontogenetic band will shift southeast into southeast Minnesota, northeast Iowa, and west-central Wisconsin this evening as a northern stream short wave trough moves to our north. The highest rain chances will be near the Interstate 35 corridor. For late tonight, the combination of clear skies, dry dew points, and light winds in Taylor County will allow temperatures to fall into the lower to mid 30s. On Tuesday, a closed upper level low will move northeast from Kansas into Iowa.
1158 PM CDT Mon Oct 9 2017 For the ArkLaTex, KTYR/KGGG and KELD/KMLU may see some convection with better moisture as cold front arrives overnight/early Tues. /issued 1022 PM CDT Mon Oct 9 2017/ The evening sfc analysis indicated a cold front extending from near a TUL, to just E of MLC, to TKI, to ACT and just SE of a LZZ line as of 03Z, with the sct convection that had developed earlier this evening continuing to diminish due to the loss of SBCapes/a narrow instability axis over Ern OK and Ecntrl TX.
1028 PM EDT Mon Oct 9 2017 Ridge of high pressure developing over the area will keep southerly flow and chances of showers and thunderstorms in place through the middle of the week.
506 PM MDT Mon Oct 9 2017 Current surface analysis shows Canadian high pressure building into the region from the northwest, with clearing skies. Upper level analysis shows low pressure sinking south-southeast across the southern Rockies with general trough covering the Rockies and high plains regions. As high pressure settles over the region tonight, clear skies, light winds, and dry air in place will produce chilly temperatures overnight into early Tuesday.
Generally precip free across the region currently, however isolated to scattered showers and storms may develop during the early morning hours as a weak cold front approaches. A cold front will move through during Tuesday afternoon with the potential for shower activity.
1036 PM MDT Mon Oct 9 2017 Upper low making slow eastward progress across near the CO/NM border this afternoon. Upper trough axis bisected the Dakotas NE to SW through southeast WY. Surface features included a ridge from eastern WY/NE panhandle southward through NW TX, and an inverted trough from a low in central NM to NW CO.
Lows by daybreak Tuesday will be primarily in the lower to middle 50s with high temperatures rebounding into the upper 60s to lower 70s Tuesday afternoon.
Locally, a dry and stable air mass has settled over the area in the wake of a passing cold front this morning.
A cold front will move through during Tuesday afternoon with the potential for shower activity.
Lift will be mainly due to isentropic lift, but it will be weak as winds are less than 20 kts through the low and mid levels.
A few showers will develop late Tonight over Northwestern counties along a weak trough.
High pressure is currently centered over the high plains of WY/SD/NE with a ridge extending northeast through central ND. This ridge of high pressure will drift southeast and extend from Fergus Falls to Bemidji by midnight. The cumulus clouds across the region currently are expected to dissipate quickly late this afternoon and this evening with loss of daytime heating and the high moving southeastward across the Red River Valley. but with the clear skies and deep cool air, temps should still drop below freezing across the entire area. Winds will increase from the south-southwest, while low pressure gets organized in the lee of the Rockies.
High pressure returns Tuesday with mostly sunny skies and mild temperatures. Skies will remain mostly cloudy, then thicken overnight when trapped moisture in the lower atmosphere forms a stratus layer. Skies will break up late Tuesday morning and become sunny for the afternoon hours under building high pressure. Temperatures will rise into the lower and middle-70s. Temperatures will rise into the lower and middle-70s today.
941 PM PDT Mon Oct 9 2017 Dry weather will linger over the area into Tuesday as a ridge of high pressure remains in place.
908 PM EDT Mon Oct 9 2017 High pressure will build into the region for overnight and Tuesday with continuing mild temperatures for October.
Cooler air has pushed quickly across the forecast area today, with breezy north winds keeping highs in the 50s out west. Meanwhile as the upper trof advances eastward, precipitation chances continue under areas of deformation and broader synoptic lift as the low swings from the Rockies over eastern Kansas through mid day Tuesday. Lows tonight from the low to middle 40s only rise toward 50 on Tuesday afternoon.
Tonight and Tuesday The latest RAP analysis and satellite/radar imagery show a dry cold front over southeast Wisconsin. More widespread mid-level cloud cover resides upstream over northwest Wisconsin and Minnesota, behind a secondary cold front. The trailing cold front will slide across north-central Wisconsin. With the incoming cold airmass, temps are projected to fall into the low to mid 30s over north- central WI, so will issue a frost advisory. Cooler high temps in the mid 50s to near 60. High pressure and a very dry air mass will reside over the northern Great Lakes on Tuesday night. Farther south, an upper level low is expected to track toward southern Lake Michigan, and gradually weaken as it approaches.
906 PM MDT Mon Oct 9 2017 Dry forecast tonight as heights build with a Pacific Northwest ridge edging into the area. Will have to watch the temperatures in the Park, as models have a tendency to under estimate the strength of the high pressure there often times and this could lead to stronger winds than expected.
610 PM CDT Mon Oct 9 2017 /00Z TAFS/ A cold front will move south of the I-10 corridor by 03Z. /issued 300 PM CDT Mon Oct 9 2017/ (Tonight and Tuesday) A cold front will continue to move south across the area this afternoon and through the evening hours. (Tuesday) The cold front will be clear of the area and the cold air and continued CAA will allow for below normal highs tomorrow. Highs will be in the low to mid 60s. Clear skies and light winds will allow for strong radiational cooling and overnight lows will drop into the low 40s.
747 PM CDT Mon Oct 9 2017 Main forecast concerns center around precipitation and potential for freezing temperatures in our northern counties. Ahead of the mid-upper low, large-scale forcing for ascent will continue to increase. It may take a while to saturate in the lower levels with prevailing low-level northeast flow, but point forecast soundings indicate the better low-level moisture arrives tonight. thinking the other counties that were previously in the watch will remain warmer under cloud cover.
Upper level trough moving along the BC coast toward the Pacific northwest. This should keep temperatures several degrees warmer than last night with lows in the upper 20s and 30s for most locations. The upper trough moves into the Pacific northwest Tuesday accompanied by a cold front.
Winds will begin to increase late tonight across eastern Oklahoma behind cold front and across the remainder of the area into the day Tuesday. /Issued 853 PM CDT Mon Oct 9 2017/ Cold front stretches from near KBVO TO KTUL TO KADH this evening with a broken line of thunderstorms occurring in the vicinity of the boundary.
853 PM CDT Mon Oct 9 2017 Cold front stretches from near KBVO TO KTUL TO KADH this evening with a broken line of thunderstorms occurring in the vicinity of the boundary.
1037 PM EDT Mon Oct 9 2017 A front slowly crosses midweek, then dry and warm high pressure dominates last half of the week.
/BB/ Tonight through Monday: Much warmer and humid than normal with a good chance of rain across most of the area. Water vapor imagery/RAP analysis showed the circulation around an upper level low just east of the Four Corners Region. As this system continues northeast to the Great Lakes region by evening, the associated cold front will drop into our northwest most zones by late Tuesday afternoon. Scattered to numerous showers and thunderstorms are expected to develop ahead of the cold front Tuesday. Otherwise, warmer than normal temperatures will continue. Tuesday morning lows will be near record warm lows again and be in the lower 70s.
Of course this will allow for strong radiational cooling to send temperatures well below freezing across the high country, particularly in the mtn valleys and out across the snow covered high plains. The temperature drop will be limited in many areas by the amount of water and wet snow sitting around, with quite a bit of energy going into freezing the liquid. It may be a little cooler in low lying spots with good snow cover like Boulder, Fort Collins, and Greeley. Though skies will be clear Tuesday night, minimum temperatures won't be quite so cold as tonight due to warmer temperatures during the daytime, as well as a surface lee trough forming.
/issued 610 PM CDT Mon Oct 9 2017/ /00Z TAFS/ A cold front will move south of the I-10 corridor by 03Z. /issued 300 PM CDT Mon Oct 9 2017/ (Tonight and Tuesday) A cold front will continue to move south across the area this afternoon and through the evening hours. (Tuesday) The cold front will be clear of the area and the cold air and continued CAA will allow for below normal highs tomorrow. Highs will be in the low to mid 60s. Clear skies and light winds will allow for strong radiational cooling and overnight lows will drop into the low 40s.
High pressure over Wyoming continues to keep fair skies and cool temperatures across the region for the overnight hours. Proton Previous Discussion: A broad upper ridge will continue building into Montana tonight while a trough carves out off the Pacific NW coast. But with the flow at all levels being westerly, it will work to bring in warmer air into NE Montana as moisture and dynamics stay well to our north. With enough sunshine, temperatures across the CWA should warm into the low to mid 60s.
A cold front will move through during late Tuesday morning into the afternoon with the potential for shower activity. Generally precip free across the region currently, however isolated to scattered showers and storms may develop during the early morning hours as a weak cold front approaches.
/Issued 842 PM CDT Fri Jun 23 2017/ The thunderstorms that were affecting the region earlier Today have now moved to the south and east of the forecast area as has the responsible cold front. Additional thunderstorms will be possible overnight north of the cold front with weak isentropic lift taking shape.
Cold front now entering northwest sections of the mid state.
Models are consistent in bringing the north portion of the high amplitude upper level ridge inland over the northern Intermountain Region this weekend.
615 PM CDT Fri Jun 23 2017 A cold front pushing just south of I-70 at mid afternoon will move through se IL next few hours. Much drier air ushering into central IL on breezy northerly winds, with dewpoints in the low to mid 50s from I-55 nw while muggy upper 60s to mid 70s southeast of a Rantoul to Taylorville line. A nice early summer day for central IL on Saturday with mostly sunny skies and breezy nw winds with cooler highs in the middle to upper 70s.
expect to see cloudy skies with a cold front approaching the area toward morning. Chattanooga Airport, TN 72 85 64 84 / 80 60 10 0 Knoxville McGhee Tyson Airport, TN 70 82 62 81 / 90 50 0 0 Oak Ridge, TN 71 84 62 82 / 90 40 0 0 Tri Cities Airport, TN 68 82 59 79 / 80 50 0 10 TN.
This feature will have life potentially all night as a cold front is draping in as well. The cold front will filter N/NE low level winds just as the morning stratus is lifting after daybreak and may crop up some early convection.
838 PM EDT Fri Jun 23 2017 High pressure extending into the forecast area from the Atlantic will weaken tonight ahead of an approaching cold front.
914 PM CDT Fri Jun 23 2017 Decided to extend the high risk of rip currents to 10z Saturday given the current sea state/wind. /Issued 747 PM CDT Fri Jun 23 2017/ Sea state continues conducive to high rip current risk, and thus will retain the high risk. Nevertheless, will consider extending the high rip current risk. Best place to be is at the beach but with the high risk of dangerous rip currents it's not advised to get into the water so you should only look at the water Overnight will remain quite muggy and just plain gross. Coastal troughing/convergence will be better with a bit less of a capping inversion as the mid-level ridging and heat core move towards the west.
925 PM EDT Fri Jun 23 2017 A cold front will cross the area this evening.
751 PM EDT Fri Jun 23 2017 A cold front will cross the area this evening.
1045 PM CDT Fri Jun 23 2017 A slow-moving large upper trough over the northern CONUS will make its way into the Great Lakes through the weekend. The surface cold front has steadily pushed southward to the Arkansas Ozarks, with high pressure projected to build into the central Plains over the weekend.
Seasonally quite strong Canadian high pressure bringing cooler temperatures on breezy NW winds under a variably cloudy sky. Temperatures are in the lower 80s SE to the lower 70s NW as cold air spills in. Area lows should be in the lower 50s northwest to the upper 50s southeast sections. Highs should be in the lower 70s north to the mid 70s central and south.
1002 PM EDT Fri Jun 23 2017 A cold front will drop southeast across the area this evening and will interact with the moisture from the remnants of Tropical Storm Cindy. Cold front is crossing CWA, while Tropical Depression Cindy was centered over east central Kentucky and is forecast to eject northeast tonight. An upper level trough axis is pushing directly overhead. As this occurs the cold front will move across the area late this evening, bringing an end to precip. The cold front will then clear the area early Saturday morning. Right behind the cold front winds will pickup briefly as strong CAA moves in.
High pressure will continue to ridge across the waters through the weekend with light winds becoming onshore and increasing some near the coast each afternoon.
1214 AM EDT Sat Jun 24 2017 A cold front sweeping through this morning returning comfortable humidity levels to the area. Light to moderate rainfall will continue to shift eastward this morning following the low. Much drier air evident on the low- level water vapor imagery to our west is quickly eroding the western edge of the rain as the low departs. The cold front will move through later this morning, leaving in its wake lower dewpoints and clearing skies.
618 PM CDT Fri Jun 23 2017 High pressure will settle in to the Western High Plains with the gradient slackening just a bit over the area. Likely a couple degrees warmer but still some upper 60s to lower 70s in most locations as clouds will be less than today.
749 PM EDT Fri Jun 23 2017 A cold front sweeping through early Saturday will return comfortable humidity levels by the weekend.
842 PM CDT Fri Jun 23 2017 The thunderstorms that were affecting the region earlier Today have now moved to the south and east of the forecast area as has the responsible cold front. Additional thunderstorms will be possible overnight north of the cold front with weak isentropic lift taking shape.
The primary forecast question is how far south will the cold front reach, as well as the coverage and intensity of any showers or thunderstorms associated with it. Presently the cold front is analyzed from near Hobbs NM northeast through southeastern OK and slowly making its progression southward. Elsewhere, the hi-res models also show convection developing across north Texas early Saturday morning as a cold front moves southward. We should see enough convection to help usher the cold front southward during the morning hours on Saturday. The front will likely halt it's southward progress during the afternoon and should remain north of the Highway 90 corridor.
/issued 344 PM CDT Fri Jun 23 2017/ Showers and thunderstorms this afternoon have continued to gradually shift to the east this afternoon with the low level convergence axis shifting off to the east. The high PWAT airmass in the wake of Cindy will aid in high rainfall rates, so some locations could get some hefty amounts and thus a small risk of exceeding flash flood thresholds.
Temperatures have cooled since this afternoon and with the trend toward cooler temperatures for Saturday the Heat Advisory for the interior portions of the East Bay, Santa Clara county and the mountain of Monterey and San Benito Counties will be allowed to expire at 9 pm tonight. Coastal areas will see little change while inland temperatures will see larger changes as cooler marine air reaches farther inland. Low clouds and patchy fog will also return to the region this weekend as an approaching upper level trough deepens the marine layer.
1041 PM EDT Fri Jun 23 2017 High pressure extending into the forecast area from the Atlantic will weaken tonight ahead of an approaching cold front.
Deep layer ridge with warm temperatures aloft kept convection isolated today. Low temperatures tonight will be in the low to mid 70s.
Cool and breezy conditions will continue into Saturday as an upper trough sits over the region. The upper flow through the next few days will be mainly northwesterly with a trough to the east and a slowly eastward migrating ridge to our west.
1019 PM EDT Fri Jun 23 2017 A cold front will cross the area this evening.
611 PM CDT Fri Jun 23 2017 A slow-moving large upper trough over the northern CONUS will make its way into the Great Lakes through the weekend. The surface cold front has steadily pushed southward to the Arkansas Ozarks, with high pressure projected to build into the central Plains over the weekend.
Stratus stayed in over most of the plains today to produce a cooler than the already cool forecast we had. An upper ridge from Arizona over the west coast will continue northwesterly flow aloft across the area through Saturday. Some cloud cover will likely remain over the plains tonight, more than originally forecast, so have gone ahead and warmed the lows by a couple degrees. The upper ridge will build in slightly to allow for warmer temperatures tomorrow, readings in the low 70s are likely over the plains, and 60s to 70s over the high terrain.
833 PM EDT Fri Jun 23 2017 Cooler and much drier air is now filtering into southeastern Michigan with sub 50 degree dewpoints now being reported in the Tri Cities region. Redevelopment of showers and a few thunderstorms will continue through late afternoon before cooler and less humid air arrives behind the cold front and brings an end to activity by early evening. A clearing trend with cooler and less humid air will follow the exit of early evening showers/storms through the overnight and Saturday morning. This will occur under cool temperatures aloft carried in by the upper level trough now over the Midwest which will bring 500 mb temperatures from around -9 C today to around -18 C Saturday afternoon and evening. Daytime heating that will lift high temps into the lower 70s will produce at least scattered convection over lower Michigan.
1155 PM CDT Fri Jun 23 2017 For the ArkLaTex, a line of convection with only occasional thunder now, is draped along a cold front over NE TX and along an intersecting outflow from KGGG to KAEX. The cold front will filter N/NE low level winds area wide just as the morning stratus is lifting after daybreak and additional convection may crop up toward daybreak and linger all morning.
947 PM EDT Fri Jun 23 2017 A low pressure system sliding east of our forecast area will keep our weather unsettled through the weekend. Coverage will continue to increase late this afternoon and into the evening as the surface cold front in southern Ontario begins dropping toward the area and interacts with a very moist airmass. Complex upper pattern in the short term and beyond with a broad trof over the eastern third of the country and a ridge in the western Atlantic.
Thunderstorms, in advance of an approaching cold front, will continue to spread south, from the north, tonight. The cold front will likely be near or just south of the Interstate 20 corridor, in the Big Country, by midnight. /issued 345 PM CDT Fri Jun 23 2017/ (Today and Tonight) Another hot day across West Central Texas, with both the upper level ridge in place as well as the low level thermal ridge. Also, isolated storms have developed close to a cold front across the South Plains, just northwest of the Big Country. Going with the highest Pops across the Big Country(likely) and chance Pops further south. The cold front will move south across the area tonight, and be located just north of the I-10 corridor by Saturday morning. For Saturday, expect much cooler temperatures with highs mainly in the 80s.
