941 AM EDT THU JUN 9 2016 High pressure to our west builds across the area through the end of the week.
633 AM CDT THU JUN 9 2016 The heat is on! Upper ridge axis stretched well into central Canada at 06Z with scattered pockets of convection over central and western Nebraska. One thing to note in tonights model runs however is a faster translation of the initial ridge axis to the east compared to past runs. At this time POPs remain on the low end but adjustments may be needed in later forecasts if similar trend shows up in the drier models.
Weak high pressure continues to hold across the coastal waters, with winds and seas expected to hold at less than headline criteria.
Upper trough over the West Coast will keep seasonably cool onshore flow in place today with a 2000 foot marine layer in place this morning.
1229 PM EDT THU JUN 9 2016 Low pressure in the Gulf of St Lawrence will bring showers to Northern Maine today and tonight.

Satellite indicating scattered to broken mid and upper level cloudiness over much of the forecast area associated with persistent east Texas trof. Moisture progged by models to increase significantly through the day primarily associated with aforementioned east Texas trof progged to advance east and gradually fill. Moisture lowers slightly Friday with loss of trof and a drier southwest flow incoming aloft.
Upper trough over the West Coast will keep seasonably cool onshore flow in place today.
Dry and sunny conditions are largely anticipated as a high pressure ridge shifts over the region from the west. Will have one more day in the upper 80s today before the majority of north and central Georgia sees a warm up into the 90s as a result of the suppressive ridge. 31 Computer models continue to support a dry forecast through the weekend as a large upper ridge remains anchored over the deep south.
Significantly cooler today, but still warmer than normal. Cold front passed through our area last night. Cool upper low is now approaching from the Gulf of Alaska.
A weak upper level trough that has been in place over northern Colorado all weak will be nudged eastward today as rising heights move into the state from the west.
This pattern is set to continue well into Friday and the beginning of the upcoming weekend as well as the H5/H7 ridge will begin to crest over the region. Warmest day looks to be on Friday as ridge axis is over the area.
Temperatures across the region ranged from the upper 40s over the eastern KY coal fields to the lower-mid 50s across western KY. With the core of the high pressure moving off to the east, we'll start to re-introduce southerly flow into the region. Highs today will range from the upper 70s in the east to the lower 80s in the west. The models still suggest that an MCS will develop along the warm front across the upper Midwest. Lows tonight will be a little milder with upper 50s to the lower 60s. Mainly dry conditions are expected on Friday as the mid-level ridge axis builds in from the west.
High pressure over Indiana will move on to the east as a warm front moves from the middle Mississippi valley to the southern great lakes. This warm front may produce a few thunderstorms mainly over northern and east central sections by tonight. An upper ridge over the central U.
while a mid-level ridge transverses east across the area. The continued light NE flow will keep temps today in the upper 80s and lows in the lower 60s tonight.
953 AM EDT THU JUN 9 2016 High pressure remains today.
Southwest flow will develop across the region today and continue through the weekend as an upper trough deepens along the west coast. Moisture working north ahead of this trough will start to spread into Utah Friday night and remain in place through the weekend.
The strong theta-e advection will slowly subside this morning as the low level jet veers to the east-southeast and weakens. Potent warm front will lift north across the area during the day Friday, leading to another surge of warm air but also moist deep South air into the region. While some storms may be ongoing early in the day, the thinking is that some partial clearing behind the warm front will allow for added instability for later in the day. Storms are then expected to develop late afternoon in the Dakotas, specifically near the Fargo area, which may then drive southeastward behind the warm front across central and southeastern Minnesota into southwestern Wisconsin.
The dry airmass currently over the region will only slowly moderate, as the low-level flow, although becoming southerly today, will be weak through the period.
630 AM CDT THU JUN 9 2016 Surface map early this morning has a warm front arching from southern SD through north central IA. Otherwise, temperatures early this morning ranged from the upper 40s/lower 50s northeast of I-94 to the lower and middle 60s along and west of the Mississippi River. Models show the warm front lifting to along the I-90 corridor by this afternoon/early evening. Thinking there will be redevelopment this afternoon into this evening along the warm front with daytime heating and as moisture transport increases/impinges on the frontal boundary. The warm front pushes northeast of the I-94 corridor on Friday with fairly stout capping taking place behind the front.
This morning was pleasant with overnight lows ranging from the lower to upper 50s across the TN Valley which is several degrees below normal.
KAMA VAD wind profile continues to measure southerly winds of 30 to 40 knots through the lowest 3000 feet.
water vapor imagery continues to show broad upper ridging across the Rockies with a weak wave of energy moving downstream through the Central High Plains. More importantly however is the latest surface analysis which places a warm front from southwest Minnesota into north-central Missouri. And we certainly won't have to wait long to begin experiencing this warmth as many areas will climb into the lower 90s this afternoon. Aforementioned ridge axis to continue sliding east on Friday as longwave troughing begins digging into the Pacific Northwest. This will allow for high temps of a degree or two warmer than today.
Temperatures will warm well into the 80s, and possibly into the lower 90s out toward the Kansas and Missouri border. This increase in moisture will lead to warmer overnight temperatures.
1040 AM EDT THU JUN 9 2016 High pressure will settle across the region today and tonight, then move offshore on Friday. Today: Clear skies and very comfortable temperatures this morning as high pressure settles in directly overhead. Highs this afternoon in the low to mid 80s with dewpoints in the very comfortable upper 40s to lower 50s range. Given airmass modification with the lack of any advection, we should see low temps a bit warmer than this morning.
The sky should bubble with quite a few diurnally-driven cumulus clouds this afternoon, but believe precipitation chances should still remain quite low with little in the way to force convection in the presence of generally subsident air on the backside of the Gulf Coast upper low.
659 AM CDT THU JUN 9 2016 07z/2am surface analysis shows ridge of high pressure extending from the Great Lakes into the Ohio River Valley. Convection has developed in advance of the low across southern Minnesota into northern Iowa where temp/moisture advection is maximized along the nose of a 30-40kt 850mb jet streak. As low and associated warm front shift further E/NE, scattered convection will shift out of the KILX CWA this afternoon. Once winds switch around to the S/SW, a much warmer airmass will spill into the area.
A warm front currently over the eastern CWA is the focus mechanism for convection this morning. An area of low pressure and associated cold front will slide across southern Canada late this afternoon and through the overnight hours. Thunderstorms will develop along the cold front over eastern MT and western ND where better instability and deep layer shear will be located.
851 AM EDT THU JUN 9 2016 High pressure will maintain dry and cool weather today.
Warm, near seasonable temperatures will prevail through the period, with highs in the upper 80s to mid 90s across the region, and lows in the low to mid 70s.
Satellite shows a plume of moisture moving into the region associated with an offshore upper low. Temperatures much cooler with highs mostly in the 70s. The upper low will move into the Pac NW tonight and Friday with a good chance of rain. Temps cooler Fri with 60s to lower 70s.
An approaching low pressure weather system will keep the airmass unsettled today.
1124 AM CDT THU JUN 9 2016 High pressure ridge has slipped off to the east and an upper level disturbance has moved through the region north of ILX. 07z/2am surface analysis shows ridge of high pressure extending from the Great Lakes into the Ohio River Valley. Convection has developed in advance of the low across southern Minnesota into northern Iowa where temp/moisture advection is maximized along the nose of a 30-40kt 850mb jet streak. As low and associated warm front shift further E/NE, scattered convection will shift out of the KILX CWA this afternoon. Once winds switch around to the S/SW, a much warmer airmass will spill into the area.
629 AM CDT THU JUN 9 2016 A weak upper level trough axis currently over Colorado will migrate slowly eastward today, and should spark off thunderstorms across Western Kansas for this afternoon/evening.
Deep layer ridging will continue across the central gulf coast with precipitable water values around 1 inch. Highs today will climb into the low to mid 90s away from the coast.
Ahead of this, there are some clouds over and near the higher terrain from Mount Shasta northeastward. This frontal system will continue to progress across the forecast areas this afternoon through this evening, giving rise to some measurable rainfall in the form of showers for portions of the west side, especially the higher terrain of the Cascades and in Douglas and Coos Counties.
903 AM EDT THU JUN 9 2016 Low pressure in the Gulf of St Lawrence will bring showers to Northern Maine today and tonight.
High pressure will cross the Central Appalachians heading for the Atlantic Coast this afternoon while upper level heights increase slightly across the area. Overnight lows tonight will ne in the low to mid 60s. As the warming air continues to be pumped out from the southwest, a slight jet streak will develop over the CWA and allow a weakness to develop inside the high pressure cell.
This ridge aloft over the region is fairly "dirty" will periods of mid/high clouds at times which may limit MAX temps at times but still expecting lower to middle 90s widespread across inland areas with heat indices close to 100 degrees.
An upper ridge will continue to bring hot and humid conditions to western Nebraska.
1217 PM EDT THU JUN 9 2016 High pressure to our west builds across the area through the end of the week.
Southwest flow will develop across the region today and continue through the weekend as an upper trough deepens along the west coast. Moisture working north ahead of this trough will start to spread into Utah Friday night and remain in place through the weekend. Warm high pressure remains over much of the southwestern CONUS this morning, with a large trough over the Pacific Northwest. Utah and southwest Wyoming are under a southwesterly flow aloft ahead of this trough, with a blanket of cirrus over a fair amount of the area.
733 AM EDT THU JUN 9 2016 High pressure will maintain dry and cool weather today.
Given the deeper mixing expected across portions of central MO, wud normally have forecast a little warmer for this area. However, have been forecasting too warm lately for this region lately and will go slightly cooler for today.
/issued 320 AM CDT THU JUN 9 2016/ High amplitude ridging continues across the Central CONUS with a weakness noted on the eastern periphery of the broad high pressure center over the desert southwest. The upper ridge will be in full force Friday by covering half the CONUS and extending into Saskatchewan Canada. The vort lobe will hang around into the weekend along with precip chances before being booted off to the east by an approaching trof from the west.
513 AM MDT THU JUN 9 2016 Upper ridging continues across the central CONUS with the main axis crossing the Dakotas today. Upper trough is developing across the wrn CONUS with flow aloft becoming more southwesterly. Weak high pressure will set up just east of the CWA on Friday bringing back the warmer air. eastern pac troughing will support sw flow into the region by late in the weekend. This will eventually support cooler conds and a little better chances for rain. Very warm conds can be expected Sat as the thermal ridge pushes over the region, with mid to upper 90s and even some 100s expected on the sd plains.
Expect another dry day today as high pressure remains in control. Highs today look to be in the low to mid 90s.
