1246 AM EST Thu Jan 12 2017 More rain is expected today ahead of a cold front. Also concerned with strong wind gusts, particularly over the higher elevations, as low level jet is providing winds in excess of 60kts just above 2000ft. The next cold front will keep in the risk for showers throughout the day, with the best chance coming during the afternoon, as the boundary approaches. There is the potential for these stronger winds to mix down to the surface, however, the greatest threat for advisory level winds will remain over the higher elevations, as the region remains in the warm sector. Have increased wind gusts for the entire area today and may end up issuing an advisory for the ridge counties. High pressure will build over the eastern Great Lakes behind the front, keeping the area dry on Friday.
320 AM CST Thu Jan 12 2017 High pressure centered well off the Atlantic Coast extending southwest into the eastern Gulf of Mexico early this morning. Low pressure over Lake Huron has a cold front to the southwest into west Texas. upper ridging developing over the Florida Keys, with southwesterly flow over much of the southern 2/3 of the country. Between ridge building over Florida and the eastern Gulf, and upper low digging into Baja California, not going to be much change in the pattern for the local area through the weekend.
High pressure was centered off the east coast with a stalled front from the Great Lakes to Central Plains. Even with overcast skies, rain chances look low through the rest of the night with a warm front well to our north. mostly in the lower 60s. Look for south surface winds to remain quite gusty through 23z/12, then become northwesterly at CKV and BNA between 00z and 06z/13, as a cold front slides in.
459 AM EST Thu Jan 12 2017 Air temperatures in Keys island communities at this hour vary between the mid 60s in portions of the lower Keys to the lower 70s in the mid and upper 60s. However, trajectories are covering a large oceanic expanse now, given the position of an expansive high pressure cell, extending from the Grand Banks of Newfoundland, all the way to Mexico. The cooler water (and air) over Florida Bay and the Gulf of Mexico seems to affecting shower maintenance and intensity. Aloft, deep ridging and large-scale subsidence prevail, and indeed, most of the rain is falling from shallow convective cells.
1014 PM MST Wed Jan 11 2017 Current surface analysis shows arctic front south of the forecast area, with high pressure centered over northern MT. By Friday, weak upper ridging will develop over the northwestern CONUS, and the Canadian low pressure systems will shift eastward, along with the arctic airmass.
Winds have decreased with the loss of daytime heating along the Lower Texas Coast this evening, therefore the Small Craft and Wind Advisories have been allowed to expire. Have mentioned low level wind shear with the low level jet expected to remain strong overnight at around 2000 feet across all TAF sites. /issued 247 PM CST Wed Jan 11 2017/ SHORT TERM (Tonight through Thursday Night): Winds will ease off tonight as a Plains low pressure system fills and loses definition as it tracks to the northeast, allowing the pressure gradient with Northeast Gulf high pressure to relax.
Upper level ridging will build in from the south through the day, with zonal flow prevailing. At the surface, generally SSE flow will continue on the western periphery of high pressure.
Medium to High Dry weather will likely prevail through the daytime hours Friday under strong high pressure.
1234 AM EST Thu Jan 12 2017 A warm front pushes north tonight. A cold front crosses Thursday night, but stalls just south of the area Friday. Warm front will cross from south to north through the remainder of the afternoon, bringing showers back into the picture. Once the warm front passes, temps may actually climb a bit overnight with everyone waking up to a very warm morning. Winds will be gusty at times tonight, especially on the hilltops and ridges. Despite the cloud cover, temps should surge well into the 60s across the lowlands, with a few locales perhaps touching the 70 degree mark. Cold front will sink southward Thursday night and Friday, and stall south of the area Friday night.
741 PM EDT Mon Oct 10 2016 A large high pressure system overhead will keep our skies clear tonight and allow temperatures to tumble. Widespread frost and freezing conditions are likely. Warmer air will return for Tuesday under mostly sunny skies. but will dry out quickly aft dark with subsidence under the high. For Tuesday night, high slides off to the N/E with light southerly flow beginning to develop as low pressure moves north into Great Lakes.
807 PM EDT Mon Oct 10 2016 23Z sfc analysis shows high pressure off to the northeast keeping the weather quiet over eastern Kentucky this evening. Currently readings vary from the upper 40s in the deepest eastern valleys to near 60 on the ridges. Dewpoints are generally in the low to mid 40s across the area with winds light and variable. Surface analysis this afternoon indicating high pressure centered north of the area across the Eastern Great Lakes. Upper level wise we are under a ridge, but a 500 mb short wave will eject into the upper midwest tonight. This and the low level WAA will lead to warming temps both max and min through the end of the period. The period will begin quiet and warm with high pressure in place.
747 PM EDT MON OCT 10 2016 Dry and cool high pressure will dominate through midweek. A dry cold front will push through the region late in the week. High pressure will return for the weekend. An h5 ridge axis will also be near the area through the period. High pressure centered over the New England states will continue ridging into the region through the period.
The cold front extended from south of BDE to Englevale ND and continues to move slowly south and east. Cold front was located roughly from south of BDE to south of Valley City, ND. Cold front will plod southeast overnight. Cold front continues to propagate slowly east and now through roughly the NW 2/3 of the forecast area or a line from BDE-FAR-Lisbon. Main mid level trough will begin to swing across the northern rockies/northern high plains Tuesday.
1051 PM EDT MON OCT 10 2016 Currently - A large area of high pressure blanketing the eastern United States is responsible for moderate to fresh northeast breezes across the Florida Keys area. Deep layered ridging and stable conditions will continue. A large high pressure system spanning the eastern United States will maintain moderate to fresh northeast breezes across Florida Keys waters through the overnight.
623 PM CDT MON OCT 10 2016 Updated aviation portion for 00Z TAF issuance Warm again tomorrow, then turning cooler mid-week.
928 PM EDT Mon Oct 10 2016 Upper level ridging holding strong tonight.
1007 PM EDT Mon Oct 10 2016 Low pressure east of Nova Scotia will pull away from the region tonight. High pressure across the eastern Great Lakes will build to the New England coast Tuesday.
708 PM EDT Mon Oct 10 2016 High pressure over the central Great Lakes will move to New England by Tuesday.
851 PM EDT Mon Oct 10 2016 The 00Z sounding showed the low level have moistened up, and Sct/bkn 3-5kft cigs were observed across northeast Florida.
00Z ILX and forecast soundings suggest the low levels of the atmosphere will remain too dry locally to support measurable rainfall overnight.
526 PM MDT Mon Oct 10 2016 Current surface analysis shows cold front sinking slowly south across northeast WY and SD. Strong jet ahead of the trough will help to push the front south and east of the area tonight. Temps range from around 60 over portions of far northwest SD to the lower 80s across far southern SD.
A frontal boundary will continue to drift southeast overnight, with a cooler airmass gradually sinking into the cwa. Tuesday night becomes fairly active as mid level trof moves across the forecast area. According to the GFS a pretty good pv anomaly/trop fold will accompany the trof passage.
753 PM EDT Mon Oct 10 2016 High pressure will slowly shift over our region tomorrow.
The only thing to mention is some high clouds streaming across the region as the 500mb pattern transitions from ridging in the southeast U.
655 PM CDT MON OCT 10 2016 A cold front is going to be the main weather concern over the next 24 hours. Initially in the extended the main concern will be the passage of a trough axis and its associated cold front.
High temps of upper 70s to low 80s are expected today which is slightly cooler than yesterday due to the little bit of cloud cover and the slight cold air advection. Lows tonight will also be slightly cooler due to the same reasons added with the clearing skies that will increase radiational cooling. Today's easterly winds were not be as breezy as yesterday's northerlies, since the pressure gradient has relaxed somewhat with the high pressure's influence. High pressure ridge will remain over the Northeast.
906 PM EDT Mon Oct 10 2016 Canadian high pressure will build across the northern Mid- Atlantic through tonight before shifting offshore during the middle of the week.
Cold front was located roughly from south of BDE to south of Valley City, ND. Cold front will plod southeast overnight. Cold front continues to propagate slowly east and now through roughly the NW 2/3 of the forecast area or a line from BDE-FAR-Lisbon. Main mid level trough will begin to swing across the northern rockies/northern high plains Tuesday.
Sfc lee trof may allow for some low level moisture to back sufficiently wwd for lcl br or mvfr cigs extending along and east of a line from KCNM-KROW-KCVN 11/09Z-15Z but confidence rather low due to the lee trof position. More or less zonal flow through the entire seven day period with a few short wave troughs embedded in the flow. They will bring temporary bouts of cooler temperatures, but not much precipitation.
Subsidence inversion in place with broad high pressure along the eastern seaboard.
1153 PM EDT MON OCT 10 2016 VFR conditions will persist this forecast as dry low level flow from the southeast to south continues to funnel into area around high pressure to the east. Resident high pressure will ensure the column remains dry in advance of this feature, and forecast soundings Tuesday suggest nothing more than virga or maybe a high-based sprinkle.
1022 PM EDT Mon Oct 10 2016 Canadian high pressure will build across the northern Mid- Atlantic through tonight before shifting offshore during the middle of the week.
/issued 200 PM EDT MON OCT 10 2016/ Aloft - A ridge centered near the central Gulf coast reached to the Great Lakes. Surface - High pressure across the lower Great Lakes sprawled south and covered most of the Gulf of mexico region. The upper ridge shifts eastward. This will push a weak cold front into the southeast U. A re-enforcing area of dry high pressure is expected to build into the region keeping NE low level flow in place through the weekend but mainly dry conditions will persist as temps remain slightly above climate normals. High pressure moves to the eastern seaboard TUE and resides there through the week. There will be slightly drier air for the next day or two but cooler temperatures will keep the RH from dropping to critical levels.
722 PM EDT Mon Oct 10 2016 Cool and dry Canadian high pressure will build over the region this week, bringing the coolest air of this early Fall season.
821 PM EDT Mon Oct 10 2016 Cool and dry Canadian high pressure will build over the region this week, bringing the coolest air of this early Fall season.
become more north-south oriented, as a short wave trough digs south through Washington and Oregon. Overnight the entire frontal band will move southeast as the short wave trough comes completely in.
However, given SW winds (which don't tend to be conducive for fog development) up around 8 kts should keep the low levels obscuration free. An upper level high pressure ridge centered over Chihuahua, Mexico will gradually expand north and east resulting in upper height rises across all of the southern Great Plains through Tuesday. Highs Tuesday expected to reach upper 80s most areas on the Caprock and probably just into the lower 90s at a few places in the Rolling Plains, around a dozen degrees above normal.
1201 AM EDT Tue Oct 11 2016 Low pressure east of Nova Scotia will pull away from the region tonight. High pressure across the eastern Great Lakes will build to the New England coast Tuesday.
A weak cold front will cross the forecast area Tuesday afternoon through Tuesday night.
929 PM EDT Mon Oct 10 2016 High pressure will build in from the west tonight and will crest over the region on Tuesday.
812 PM MDT Mon Oct 10 2016 Weak disturbance will move across after midnight with any pcpn with this feature limited to the higher terrain. Cross sections indicate 20-30kt cross barrier flow so some gusts up to 40 mph in the higher mountains and east slopes. Weak surface cold front will brush far Northeast Colorado early Tuesday morning but looks to have minimal effect except cooler temperatures.
Surface trof advancing west across the near coastal waters and accompanied with a few showers. High pressure is moving east across the Great Lakes region this afternoon. This ridge had been producing a generally northeast flow over the past couple of mornings which was providing pleasant weather. The ridge will continue to move into New England and this will turn the flow off the gulf which will increase moisture levels and temps.
Therefore, radiational cooling will cause temperatures in many locations to fall below freezing, and Freeze Warnings will remain in effect for Central Oregon, the John Day Basin, and the Grande Ronde Valley. Patchy fog will also be possible, especially near the lower Yakima and Columbia rivers.
23Z sfc analysis shows high pressure off to the northeast keeping the weather quiet over eastern Kentucky this evening. Currently readings vary from the upper 40s in the deepest eastern valleys to near 60 on the ridges. Dewpoints are generally in the low to mid 40s across the area with winds light and variable. Surface analysis this afternoon indicating high pressure centered north of the area across the Eastern Great Lakes. Upper level wise we are under a ridge, but a 500 mb short wave will eject into the upper midwest tonight. This and the low level WAA will lead to warming temps both max and min through the end of the period. The period will begin quiet and warm with high pressure in place.
1004 PM EDT Mon Oct 10 2016 High pressure will slowly shift over our region tomorrow.
A weak upper trough centered over central Iowa will keep a stream of partly to mostly cloudy cirrus across the local area overnight. Temps as of 6PM are in the lower 70s with dew points in the upper 30s to lower 40s. Expecting another cool night tonight but with the cloud cover, it will be a few degrees warmer than the last two nights, in the lower to upper 40s.
Expect VFR conditions to prevail tonight into early Tuesday as the 500mb ridge across northwest Mexico continues to provide subsidence across northeast Mexico and deep south Texas. This brief breaking down of the dominate ridge of high pressure will allow a weakly inverted trough. As the mid level trough approaches the RGV. it will generally dissipate as it encounters the eastward expanding H500 ridge that will build back over Northern Mexico/Southern Texas. the westward moving trough will be pushed southward as high pressure centered over the East Coast builds down into the Texas Gulf Coast. The building back of the high pressure will lead to near normal lows.
714 PM EDT Mon Oct 10 2016 High pressure will maintain dry weather through mid week.
Instead, expect overnight lows to range from the low 50s across southeast Alabama, to the mid 50s from Tallahassee through Valdosta, up to the upper 50s or near 60 degrees along the coast and across the southeast Big Bend.
Radar picking up some light returns in southeast Missouri, but the low levels are so dry, nothing will make it down to the ground. Again, the low levels remain very dry so little or no chance of rain in the very short term.
916 PM EDT MON OCT 10 2016 High pressure keeps dry weather going through mid weak.
Expect low temperatures generally in the low 40s with some upper 30s possible in our normally cold zones. The upper level ridge is expected to shift slightly east on Tue, with the ridge axis situated along or just offshore the Carolina coast. Meanwhile, strong (~1030 mb) high pressure over the northern Mid-Atlantic today will shift to the New England coast on Tue.
1055 PM CDT MON OCT 10 2016 Updated aviation portion for 06Z TAF issuance Warm again tomorrow, then turning cooler mid-week.
/issued 245 PM CDT MON OCT 10 2016/ WV imagery shows the upper trough approaching the MS Valley, leaving West Texas and Southeast New Mexico under generally zonal flow aloft. Otherwise, temps have rebounded back to above normal, w/models trending even warmer than they have the past few days.
1137 PM EDT Mon Oct 10 2016 High pressure will slowly shift over our region on Tuesday.
927 PM CDT Mon Oct 10 2016 The upper trough that is over Iowa continues to spread cirrus clouds across the local area. As well, current dew points are a few degrees warmer than previously forecast. This has also impacted the slightly warmer low temperature forecast.
946 PM EDT Mon Oct 10 2016 High pressure over the central Great Lakes will move to New England by Tuesday.
1048 PM EDT Mon Oct 10 2016 High pressure will build in from the west tonight and will crest over the region on Tuesday.
1012 PM EDT MON OCT 10 2016 Dry and cool high pressure will dominate through midweek. A dry cold front will push through the region late in the week. High pressure will return for the weekend. An h5 ridge axis will also be near the area through the period. High pressure centered over the New England states will continue ridging into the region through the period.
Temperatures are trending cooler this evening most noticeably in the delta which is 11 degrees cooler this evening than last evening. Temperatures will be cooler the next couple of days but near seasonal normals as the high pressure system continues to break down.
721 PM EDT MON OCT 10 2016 High pressure keeps dry weather going through mid weak.
209 AM EDT TUE JUN 7 2016 A cold front will slip southeast through the region overnight.
129 AM EDT TUE JUN 7 2016 A cold front will approach from the northwest overnight and pass through the region on Tuesday. The front will work offshore by Tuesday night allowing a drier and cooler airmass to swing in as high pressure builds in from the west.
416 AM EDT TUE JUN 7 2016 High pressure will move from the northern plains this morning to the midwest tonight in the wake of a departing cold front.
A dry cold front approaching from the northwest will move into the state during the afternoon. An upper level trough sweeping through the eastern states will reinforce a drier northwest flow ahead of the front allowing for clearing skies today. 16 Long range models continue to agree on a dry forecast at least through the weekend as high pressure builds over the region and dominates.
323 AM PDT TUE JUN 7 2016 High pressure will build in by midweek with peak temperatures on Wednesday and a persistent coastal marine layer.
Dry high pressure will then build in from the northwest and linger through the remainder of the week. The front should start to make more eastward progress through daybreak as the upper trof axis moves in from the west. Cannot rule out a stray shower E of the Blue Ridge where low level convergence is maximized downwind of the higher peaks. High pressure will continue to build in tonight with mostly clear sky and low temps a few degrees below normal. As of 255 AM Tuesday: on Wednesday, the region will remain under dry NW flow as the H5 trough axis swings over the Atlantic coast. At the sfc, high pressure will build across the southern Appalachians from the Mid West.
Meanwhile an Atlantic ridge extends west southwestward into the Western Caribbean Sea. Wind speeds through the lower levels continue in the 25 to 35 knot range, while surface winds are moderate to fresh out of the south southwest. Forecast - Accelerated confluent flow between Colin's trailing trough across North Florida and the ridge to our south will continue pumping deep tropical moisture across the Florida Keys and surrounding waters. Support aloft will be lacking as there is a weak anticyclone broadly located across the area above 500 mb. This will allow the ridge to our south to lift northward.
557 AM EDT TUE JUN 7 2016 Cooler weather is forecast through the middle of the week before we warm back above normal by week's end. Fries Upper-level trough axis will shift quickly to our east Wednesday leading to a drying and clearing trend through the afternoon. Deep mixing Wednesday morning means gusty winds will be common as the trough passes, but these should lessen by afternoon as the pressure gradient loosens.
Pattern overview: Short wave trough axis/cool air and abundant cloud cover in the process of sagging down through northern Michigan this morning, dragging a batch of light rain/drizzle down through the region. Today: Short wave trough axis and batch of light precip will slide down and out of the CWA this morning, followed by a gradual low level drying trend as we go through the afternoon.
Mostly clear and warm elsewhere with high pressure aloft. Over the weekend it will turn a little cooler as a low pressure trough moves across southern California.
327 AM CDT TUE JUN 7 2016 Noticeably less humid air overspreading the region this morning following the passage of last night's cold front. early morning water vapor showing a large ridge of high pressure building across the northern Rockies. aforementioned high pressure expected to slide off to our east as upper ridging translates east from the Rockies. This will allow for the return of southerly flow and the return of more humid air as a weak warm front lifts through the region. Models show some QPF directly to our north and west as the low-level jet impinges upon the boundary.
High pressure will building in from the west the west this afternoon and persist through late in the week. A mesoscale warm frontal feature is setting up along the beaches per recent observations and as Colin redevelops off the northeast Florida coast, there is still a chance increasing low- level convergence along the meso-front could support a resurgence of steadier rainfall. The best chances for this happening is along the lower South Carolina coast. Highs will reach the lower 90s inland with upper 80s to around 90 closer to the coast.
250 AM MST TUE JUN 7 2016 A gradual cooling trend will take place through this weekend as high pressure is slowly displaced and as moisture increases later in the week.
638 AM EDT TUE JUN 7 2016 Cooler weather is expected today into Wednesday as an upper level trough moves through. Clearing is expected tonight into Wednesday as high pressure builds in.
Departing low pressure will bring more showers and thunderstorms to eastern and northern Nevada this afternoon and evening.
SHORT TERM (Today through Wednesday): Elongated 500 mb low pressure along the entire coastline of Texas will gradually close off and become centered over Deep South Texas and the Rio Grande Valley during the forecast period.
All sites will see gusty west-to-northwest winds later this afternoon as the pressure gradient tightens across the area due to an upper level trough swinging across the region.
The upper level low pressure system over northwest Utah will gradually weaken as it track east across the region through tonight. High pressure aloft will strengthen once again across the Great Basin Wednesday, then shift east as a storm system enters the Pacific Northwest late in the week.
Below normal temperatures and cooler weather is expected tonight through wednesday as strong high pressure over the upper midwest is expected to build across the Great Lakes and Ohio Valley. Cool and dry Canadian air will accompany the high.
