703 PM EDT Sun Oct 30 2016 A cold front with a weak area of low pressure that travels along it moves south of our area this evening with some showers over southern areas of New Hampshire and southwest Maine. High pressure will build in from the west later tonight and Monday. Low pressure will pass by well to our north midweek bringing warmer weather and scattered showers.
1026 PM EDT Sun Oct 30 2016 A cold front will move south of the area overnight. High pressure will build in from the west on Monday. Low pressure will pass by well to our north midweek bringing warmer weather and scattered showers.
758 PM EDT Sun Oct 30 2016 A cold front has moved south of Washington DC.
/issued 259 PM CDT Sun Oct 30 2016/ Upper level ridge axis has just begun shifting east of our longitude as trough across the west gradually deepens with system in Pacific Northwest coming onshore. Surface cold front that passed south through our CWA this morning will keep temps mostly in the 70s for our area with portions of our southernmost counties topping out in the low 80s by late this afternoon.
756 PM EDT Sun Oct 30 2016 Aviation As high pressure settles over the Michigan tonight, skies will clear and temperatures will fall to the lower to mid 30s. Breezy conditions will develop Monday afternoon as the high moves east and a cold front approaches the Great Lakes.
1029 PM EDT Sun Oct 30 2016 A cold front will push south through the area today and tonight, bringing a chance of showers. As high pressure travels east through the Great Lakes Monday into Monday night, the old frontal boundary will move back northeast as a warm front. Weak cold front pushing south of the Ohio River will continue south into the TN Valley by morning. Based on clouds have tweaked temperatures a little warmer with lows from the lower 40s north to the lower 50s far south. Surface cold front is currently pushing through the CWA and is just past KDAY with a weak line of showers out ahead. As this happens Monday the cold front that was just south of the area will stall and wash out. As this happens a warm front will slowly pull north as well.
By tomorrow afternoon a leeside trough will set up with the wind becoming S to SW.
The higher terrain over the NE BLue Mtns and in the Central Panhandle could see gusts between 45-55 mph.
/issued 251 PM CDT Sun Oct 30 2016/ Skies are mostly sunny across much of the forecast area this afternoon with temperatures in the low to mid 80s. High pressure covers much of the southern U.
The highest peaks of the Tetons, sw YNP mtns and Wind Rivers will likely be the only locations that have a decent shot of some advisory amounts. Risk is there throughout the period but those two periods have the highest risk.
(This evening through Monday) Issued at 125 PM CDT Sun Oct 30 2016 The cold front that entered the southern Missouri Ozarks today will stall out near the Missouri and Arkansas border tonight. The low level moisture behind the front will keep lingering low clouds across much of the area tonight. The nearly zonal upper air pattern will become more amplified heading into mid week as an upper level trough comes across the western states.
749 PM EDT Sun Oct 30 2016 An upper level trough and associated cold front will move through the area Monday/Monday night.
/issued 324 PM EDT Sun Oct 30 2016/ High pressure centered over the southeast plains will gradually filter in drier air into South Florida suppressing all the deeper moisture further south into Keys late this afternoon and early evening lowering the showers activity tonight across South FL. Abundant cloud-cover will keep temperatures mainly in the low 80s, with some mid-80s over the western interior.
Mostly clear skies tonight under high pressure will allow temps to cool into the mid to upper 50s overnight.
950 PM EDT Sun Oct 30 2016 Mainly dry weather is expected through mid week under high pressure.
940 PM EDT Sun Oct 30 2016 A cold front will move through the area Monday and Monday night and be followed by high pressure returning for the middle of the week.
730 PM EDT Sun Oct 30 2016 A cold front crosses tonight. It returns as a warm front Monday night.
546 PM MDT Sun Oct 30 2016 Upper ridge will remain over the central plains today and tonight followed by gradual height falls on Monday as the next system enters the Pacific northwest. At the surface, lee trough will strengthen in eastern Colorado resulting in increasing south to southwesterly winds tonight and Monday, especially in western portions of the area. Another cold front will move through late Monday afternoon with winds shifting to northerly. Temperatures will warm into the lower to middle 80s ahead of the front Monday afternoon. Monday night will begin with southwest flow into the region due to a trough over the western CONUS.
Broad upper level ridge will be the main story for the upcoming week. Ridging builds in over the region Monday morning and will persist through much of the week.
/issued 329 PM CDT Sun Oct 30 2016/ (Tonight and Monday) Going with a dry forecast the next 24 hours as upper level high pressure ridge continues to bring warm and dry weather.
Mainly clear skies drng the evening as significant temp/dewpoint depression exists in the lower levels.
1030 PM EDT Sun Oct 30 2016 A cold front crosses tonight. It returns as a warm front Monday night.
Shallow cold front has stalled in the terrain of NW AR and stretches back into SE OK. Even if the low cigs scatter out, fog could form regardless. /Issued 921 PM CDT Sun Oct 30 2016/ Shallow cold front extended from far northwest Arkansas through south central Oklahoma this evening. Once the warm front moves back north and through the forecast area.
816 PM EDT Sun Oct 30 2016 A strong U/L ridge will persist over the Gulf of Mexico and Florida for the next couple of days with strong subsidence over the region.
634 PM CDT Sun Oct 30 2016 Early-afternoon water vapor imagery depicted an amplifying mid- level ridge building through the Interior West into the High Plains, downstream from a vigorous upper low approaching the Pacific Northwest Coast. In the low levels, a ridge axis stretched from the upper Mississippi into mid Missouri Valleys as of 18z, while a lee trough was intensifying over the northern High Plains. Widespread stratus which formed last night within the low-level ridge axis is in the process of eroding this afternoon; a trend which will continue in evening. The low-level warm advection pattern will persist through Monday across the forecast area ahead a weak cold front which will approach from the west.
809 PM EDT Sun Oct 30 2016 A cold front will push south through the area today and tonight, bringing a chance of showers. As high pressure travels east through the Great Lakes Monday into Monday night, the old frontal boundary will move back northeast as a warm front. Surface cold front is currently pushing through the CWA and is just past KDAY with a weak line of showers out ahead. As this happens Monday the cold front that was just south of the area will stall and wash out. As this happens a warm front will slowly pull north as well.
857 PM PDT Sun Oct 30 2016 The gusty winds over the mountains and scattered showers will be winding down later tonight as a weak low pressure trough passes to the east.
Due to dry soil conditons and calm winds, low temperatures Sunday morning were much cooler than expected. RH values will be in the low to mid 30s each afternoon, with light winds. /Issued 637 PM CDT Sun Oct 30 2016/ Broad upper level ridge will be the main story for the upcoming week. Ridging builds in over the region Monday morning and will persist through much of the week.
High pressure essentially overhead will maintain basically calm winds.
629 PM CDT SUN OCT 30 2016 High pressure will build back into the region to start the work week. Model depiction of the low level moisture profiles is problematic. HRRR has been introducing some drying from the NE, and although there has been some erosion of the lowest ceiling over the southern half of the state. The struggle will be between general subsidence with high pressure building.
634 PM CDT SUN OCT 30 2016 A cold front will drift into the northern portions of Arkansas tonight and could bring some occasional IFR and/or MVFR ceilings and visibilities after 06Z at KHRO and KPBK.
The cdfnt to our north will stay north of the cwa as high pressure builds east overnight. The dry wx pattern will continue thru this period along with highs about 20 degrees above normal, thanks to strong upper ridging.
WV imagery indicates a weak upper level ridge of high pressure moving eastward across the Central Plains. Near the surface, a lee side trough of low pressure is anchored across eastern Colorado. Stratus gradually burning off this afternoon, with a much cooler airmass across SW KS. Cooler air will filter into SW KS just in time for the beginning of November.
1156 PM CDT SUN OCT 30 2016 Relatively quiet night across central IL as lingering low cloud cover remains while a high pressure region moving into the northern Midwest promotes partial clearing at many locations. High pressure will build back into the region to start the work week. Model depiction of the low level moisture profiles is problematic. HRRR has been introducing some drying from the NE, and although there has been some erosion of the lowest ceiling over the southern half of the state. The struggle will be between general subsidence with high pressure building.
Shallow cold front lies from East Central OK up into Northwest AR and the latest trends indicate that it has stalled. /Issued 327 PM CDT Sun Oct 30 2016/ Shallow cold front pushed to the typical location of extreme NW AR to near KMLC before stalling. These clouds have recently begun to erode however they may begin to expand again after sunset only to be pushed northward as the frontal boundary lifts northward as a warm front tonight.
515 PM MDT Sun Oct 30 2016 Upper level analysis has broad ridge across the central CONUS, with large trof moving into the Pac Northwest. At the surface, high pressure resides across the Northern Plains with a warm frontal boundary across eastern Wyoming. However, the latest runs of the HRRR, NAM and GFS are showing the possibility for a few showers from northeast WY into northwest SD overnight as the warm front moves through. Low pressure will pass north of the area Monday morning, dragging a dry cold front quickly across the area during the morning hours. Highs will range from the 60s over northeast WY and the Black Hills to the lower 80s across far south central SD. On average a trough will persist in the eastern Pacific with a ridge across the central CONUS through the period.
A warm front will push into southwest North Dakota tonight. The bulk of the moisture and the best chance for rain appears to remain across northern North Dakota through most of the day along the northern edge of the trough. Over the past hour or so there has already been fog developing at Linton and Mobridge SD. Expect ceilings to lift ahead of low pressure Monday morning with increasing winds turning west to northwest.
Today has seen extensive stratus under the large high pressure over the Midwest, but within that, there have been notably large breaks in the cloud deck, with one of these from central Iowa through northeast Iowa. Tonight, the high pressure will slowly move east into the Great Lakes region, allowing winds to turn to the east and then southeast. For this reason, it seems prudent to go a bit warmer than model forecast for overnight lows tonight, counting on at least some periods of cloud cover, and go a bit lower on guidance highs Monday as we may see clouds especially early in the day.
935 PM EDT Sun Oct 30 2016 High pressure across the western Great Lakes will shift east tonight and be overhead for Monday.
901 PM CDT SUN OCT 30 2016 Relatively quiet night across central IL as lingering low cloud cover remains while a high pressure region moving into the northern Midwest promotes partial clearing at many locations. High pressure will build back into the region to start the work week. Model depiction of the low level moisture profiles is problematic. HRRR has been introducing some drying from the NE, and although there has been some erosion of the lowest ceiling over the southern half of the state. The struggle will be between general subsidence with high pressure building.
These clouds will build farther west through the overnight hours with advection of lower to middle 50s dewpoints west into the cooler airmass (current temps in the 46-51 range). This has caused temperatures to be cooler, especially where the cloud cover has remained most of the day with highs in the low 60s. The cloud cover will prevent lows from dropping too much, with low temperatures tonight generally in the low 50s. Tomorrow, low pressure begins to build over the Rockies causing the pressure gradient over eastern Kansas to increase. Highs have been trending cooler than previous runs, but still unseasonably warm weather is forecast for tomorrow.
700 and 500 mb heights are near the max for this time of year in the SPC climatology, which is not a surprise given the high pressure in place.
815 PM EDT Sun Oct 30 2016 Rain showers and drizzle will end this evening as low pressure moves off the New Jersey coast.
Snow will continue to fall in the high terrain through Monday night but the main impact is expected Monday morning.
701 PM EDT Sun Oct 30 2016 High pressure across the western Great Lakes will shift east tonight and be overhead for Monday.
805 PM EDT Sun Oct 30 2016 High pressure will build into the region overnight, allowing skies to partially clear and temperatures to fall to between 35 and 40 degrees. Under partly cloudy skies, temperatures will rise into the lower 50s to around 60 on Monday.
1154 PM CDT Sun Oct 30 2016 Early-afternoon water vapor imagery depicted an amplifying mid- level ridge building through the Interior West into the High Plains, downstream from a vigorous upper low approaching the Pacific Northwest Coast. In the low levels, a ridge axis stretched from the upper Mississippi into mid Missouri Valleys as of 18z, while a lee trough was intensifying over the northern High Plains. Widespread stratus which formed last night within the low-level ridge axis is in the process of eroding this afternoon; a trend which will continue in evening. The low-level warm advection pattern will persist through Monday across the forecast area ahead a weak cold front which will approach from the west.
There were some light showers/drizzle that occurred this morning but as the upper ridge moved over the area, these have ended. A low level jet will develop tonight and advect moisture and warmer temperatures into the region.
The Florida Keys will be located between a high pressure system along the southeast coast of the United States and a broad area of low pressure over the northwest Caribbean Sea.
1219 AM EDT Mon Oct 31 2016 A cold front will move south of the area overnight. High pressure will build in from the west on Monday. Low pressure will pass by well to our north midweek bringing warmer weather and scattered showers.
921 PM CDT Sun Oct 30 2016 Shallow cold front extended from far northwest Arkansas through south central Oklahoma this evening. Once the warm front moves back north and through the forecast area.
A warm front will push into southwest North Dakota tonight. The bulk of the moisture and the best chance for rain appears to remain across northern North Dakota through most of the day along the northern edge of the trough. Mesoscale models appear too far west with the low stratus over western ND. Expect ceilings to lift ahead of low pressure Monday morning with increasing winds turning west to northwest.
Did lower the lows a little, mainly in the east as well. Upper ridge will remain over the central plains today and tonight followed by gradual height falls on Monday as the next system enters the Pacific northwest. At the surface, lee trough will strengthen in eastern Colorado resulting in increasing south to southwesterly winds tonight and Monday, especially in western portions of the area. Another cold front will move through late Monday afternoon with winds shifting to northerly. Temperatures will warm into the lower to middle 80s ahead of the front Monday afternoon. Monday night will begin with southwest flow into the region due to a trough over the western CONUS.
1235 AM EDT Mon Oct 31 2016 Mainly dry weather is expected through mid week under high pressure.
748 PM EDT Sun Oct 30 2016 Showers mainly south of Pittsburgh should end tonight as a cold front exits. High pressure should bring dry weather and a gradual warming trend through mid week. Showers south of PIT should end this evening with a departing cold front. Clouds should continue to persist much of the night in cool NW flow before subsidence with building high pressure results in a rapid clearing trend by early Monday morning. Flat ridging aloft will persist through this period, providing mostly dry weather.
18Z surface data has low pressure near KMSP with a frontal boundary across northern Wisconsin. A cold front ran southwest from the low into central Nebraska. Late tonight, slightly stronger forcing arrives as the cold front begins moving through the area. Depending upon the cloud cover and precipitation coverage, high temperatures may be much cooler than forecast. Decreasing 850mb temps into the lower teens and a northerly component to the sfc winds will result in a comfortable night with lows in the low/mid 60s.
1220 AM EDT THU JUL 28 2016 High pressure will expand across the Carolinas, maintaining uncomfortable levels of heat and humidity this week.
1014 PM EDT WED JUL 27 2016 A weak trough to our north and the subtropical ridge to our south have setup a frontal boundary just to our south.
310 PM EDT Mon May 16 2022 A cold front will move east of the area early this evening with a seconday cold front expected Tuesday afternoon.
Temperatures on Tuesday could be a little cooler than the past couple of days, if it stays cloudy/rainy for most of the day across the eastern half of forecast zones.
Unfortunately, temps won't cool very much with the passage of this front and highs this afternoon will still reach the triple digits for many with an upper ridge axis over the region. Despite the "cooler" temps, we will be near record breaking with 101 forecasted as the high today at Midland Int'l (current record is 102). Lee troughing off of CO will result in strong southerly surface flow over the region and temps will creep up a few degrees higher for Tuesday as we once again reach near-record breaking temps.
Mid afternoon surface analysis had a weak cold front between Interstate 20 and Highway 84. There is the low chance that the cold front may set off a storm or two across our southern most zones late this afternoon into early evening but the potential for severe storm development is thought to be too low to mention in our HWO and has been removed. This will lead to the start of a warming trend from the southwest and temperatures will top out above normal from the upper 80s northeast to the lower 90s central and south.
Much cooler air will spread into the region Tuesday with some lingering showers, especially east of Lake Ontario along with breezier conditions.
With the mid/upper level ridge building back over the state from the W/SW. This somewhat flat ridging is expected to remain in place through mid week. Lows tonight and tomorrow night are going to range from the lower to mid 70s for most inland locations to the upper 70s at the beaches.
Tonight and Tuesday The latest RAP analysis and satellite/radar imagery show an upper trough axis shifting east of the region from central Lake Superior to eastern Lower Michigan. As high pressure over the northern Plains moves into the western Great Lakes, frost potential and rain shower chances late tomorrow afternoon are the primary forecast concerns. As the upper trough continues to slide further east and away from the region, weak high pressure will be building over the western Great Lakes. Statistical guidance shows lows falling into the middle 30s across the northwoods, but stayed a degree or two warmer in case winds didn't subside as quickly in the evening. The morning will start out mostly sunny and quiet thanks to high pressure across the region. High temps will range from the lower 60s to near 70 degrees.
Upper level ridging will be in place along with northeasterly to easterly surface winds and dry air will make for fair weather through at least late this evening.
(Rest of Today) Cold front is beginning to cross into NW AL this late Mon morning, aided by an upper trough axis traversing eastward across the mid TN/OH Valley regions. Slightly cooler/drier air will then filter into the area from the north in the wake of the frontal passage, with highs later today struggling to climb past the lower/mid 80s for most spots.
Temps could still reach the lower 60s south central. Troffing across the Great Lakes starts the forecast period with seasonal temperatures.
307 PM EDT Mon May 16 2022 Thunderstorms, some severe, will sweep east across the Commonwealth late this morning through the mid afternoon hours, along and just in advance of a relatively strong cold front.
Dew points are in the 50s behind the front and while we currently have a bunch of upper level cloud cover, I think by this afternoon, with highs creeping into the low 80s and some sun, it's gonna be a good one. Tuesday should be a touch warmer but pretty similar.
1134 AM CDT Mon May 16 2022 The convective complex brushing our western zones last night helped drive a weak cold front to the edge of southern zones this morning, which of course is providing the bulk of the region with some welcome slightly cooler and less humid air. Otherwise, expect highs today generally ranging from the mid to upper 80s in northern zones to the lower 90s in southern zones. Upper ridging aloft could provide some lift as short wave departs and ridge once again pushes overhead. A 1017mb high pressure will be over SW MO by daybreak and allow for some cooler temps than we have seen lately. Then expect to get to back to summer with the ridge eventually, but more light NW flow overnight may have a little more rainfall in the offing before the drought is reinforced.
The upper level ridge that brought yesterday's record heat has shifted east into New Mexico / Texas. A dry upper trough has moved into the Desert Southwest in its place, which has aided in bringing some locally breezy winds this afternoon. Temperatures are generally running a few degrees cooler than 24 hours ago, but still warmer than normal for this time of year. Look for a very minor cooling trend this week as a general weak upper trough pattern remains over the region. A stronger trough will dive across the western US late this week. Minimum relative humidity values will be in the low single digits to lower teens with poor overnight recoveries.
Expect showers and thunderstorms to develop over the High Plains this afternoon and spread east this evening and overnight.
(The rest of today ) Pleasant May day underway, with dewpoints running about 5-15 degrees lower than this time yesterday and highs expected to reach the lower to mid 80s.
With this cloud cover, northwesterly flow, and building cooler airmass, daytime highs have largely topped out in the 50s in the west and low 60s in the east.
130 PM EDT Mon May 16 2022 Thunderstorms, some severe, will sweep east across the Commonwealth late this morning through the mid afternoon hours, along and just in advance of a relatively strong cold front.
A pattern change late week will bring stronger winds to the region, elevated fire weather threat, and slightly cooler temperatures. A system coming later this week brings some gusty winds and slightly cooler temperatures.
