Reduced visibility beneath heavier precipitation will be possible, but due to the highly variable nature of this phenomenon, I have abstained from including in the TAF at this time. /ISSUED 340 AM CDT TUE AUG 16 2016/ An upper level trough axis will remain oriented from northeast to southwest across the region today. Showers and isolated thunderstorms will be likely again today, especially to the east/southeast of the upper trough axis.
Temperatures were in the low to mid 80s. The main wx features continue to be the stream of deep moisture stretching from the Texas Gulf Coast northeastward into the Mid- Mississippi Valley and southern Great Lakes, and the strong upper level Atlantic ridge to our east. For the rest of the day, the highest probability for showers and storms will be located across the northwest third of our area, closer to the deep moisture. The lowest rain chances will be over southern sections, from Pulaski to Manchester and Altamont, where the influence of the ridge will be stronger.
No major changes to overall thinking today with low pressure tracking northeast through the St. Typically, much of the area struggles to break free from warm frontal cloudiness today which will be a limiting factor to destabilization along with warm mid- level temperatures. Sfc hipres blds in for Wed bringing drier air but upr trof will create some instabilty.
Approaching cold front will move through the forecast area Wednesday, followed by another over the weekend. Cold front currently over Il slowly inches closer today, but will not cross cwa until Wednesday. Cold front and upper level short wave support will slowly move through the region on Wednesday.
432 AM PDT Tue Aug 16 2016 High pressure will result in warm and dry weather through the upcoming weekend.
Sandwiched between a broad, stout 500mb high to its east and a broad trough to the north and west, this boundary has remained a focusing point for shower and thunderstorm development over the past several days across much of eastern Texas, southeastern Oklahoma, Arkansas, Missouri, etc. Low chances for precipitation will build slowly northward early Wednesday as the the 500mb trough over the north central U.
(Issued 249 AM CDT TUE AUG 16 2016) Not much change in the overall wx pattern, as a cdfnt continues to extend from ern TX thru the Great Lakes and an upper ridge still covers much of the sern US. Otherwise temps across the cwa at 230 am were mainly in the low/mid 70s under mostly clr skies. On Wednesday the Atlantic upper ridge begins to weaken allowing the previously mentioned cdfnt to sag towards the cwa.
The story for us continues to be the combination this stream of deep moisture stretching from the Texas Gulf Coast northeastward into the Mid-Mississippi Valley and southern Great Lakes coupled with the strong upper level Atlantic ridge to our east.
Shower and thunderstorm activity will favor the higher terrain. Weak subsidence on the backside of the aforementioned trough could inhibit convection somewhat this afternoon. However, moderate instability and moisture should lead to typical afternoon thunderstorm behavior over the higher terrain of northern Arizona later today. A similar pattern continues through the week as low pressure remains anchored over southern CA/NV and moisture values generally don't fluctuate much from day to day. By late this week a trough moving through the northern Rockies results in a more northwesterly flow, drawing drier air in from the north.
1015 AM EDT TUE AUG 16 2016 High pressure will ridge into the forecast area from the Atlantic through Wednesday.
Latest water vapor satellite imagery showing upper level trough over the Northern Plains and Upper Great Lakes region. First impulse embedded in the upper level trough is producing scattered convection over the eastern Dakotas and northwest Minnesota. Latest 07z surface analysis indicates weak high pressure over northern Wisconsin into eastern Minnesota.
A slight cool down is then expected region-wide for the latter half of the week as an upper level low develops off of the California Coast. A few far inland locations will soar into the lower 100s.
/Issued 405 AM CDT TUE AUG 16 2016/ An upper ridge will build in over the Panhandles today through Wednesday which will allow for the dry conditions to continue.
Sfc hipres blds in for Wed bringing drier air but upr trof will create some instabilty.
Latest water vapor shows an area of deep moisture along the front in advance of a weakening mid level trof that extends from the mid/upper Mississippi Valley southwest into the Red River Valley. More clouds and precip across the region in general this morning will lead to cooler highs especially over the northwest half so lowered temps a bit. Current 500mb analysis place a slow moving trof just west of the region. Expect coverage of showers and storms to continue to increase throughout the morning and into the day as the weakening upper trof continues to approach the region and deep moisture continues to surge into the region from the southwest. Strong storms will be possible but not limited to this region as a slow moving vort max associated with the deamplifying upper trof moves through the Mid-South.
648 AM CDT TUE AUG 16 2016 Latest water vapor satellite imagery showing upper level trough over the Northern Plains and Upper Great Lakes region. First impulse embedded in the upper level trough is producing scattered convection over the eastern Dakotas and northwest Minnesota. Latest 07z surface analysis indicates weak high pressure over northern Wisconsin into eastern Minnesota.
Low pressure over the southern southern lower Michigan will move northeast across the great lakes and a trailing cold front will move southeast across Indiana today. A weak high pressure ridge will build into the Ohio valley Wednesday.
Overall, the mean long wave trough over central North America will control the weather pattern across the Upper Midwest through the forecast period. A strong and persistent upper low that has been semi permanent near the North Pole over the past few weeks, has led to a positive AO (Arctic Oscillation). It also means that some of the cooler air mass from northern Canada may filter further southward. Current temperature forecast for the upcoming weekend are 5 to 10 degrees below normal, and some places maybe cooler than 10 degrees below normal if the Thu/Fri system is stronger than current models forecast.
Morning KXMR sounding shows cooler conditions in the mid levels compared with the sounding from 24 hours prior with 700/500mb temps respectively at +9. There remains fairly deep layer ridging north of ECFL that will provide this deep easterly flow through the next 24hrs.
Current 500mb analysis place a slow moving trof just west of the region. Expect coverage of showers and storms to continue to increase throughout the morning and into the day as the weakening upper trof continues to approach the region and deep moisture continues to surge into the region from the southwest. Strong storms will be possible but not limited to this region as a slow moving vort max associated with the deamplifying upper trof moves through the Mid-South.
/issued 439 AM EDT TUE AUG 16 2016/ Deep-layer ridge centered northeast of Florida will continue to be the dominant weather feature over the region. Easterly flow around the southwest side of this high pressure will occasionally bring moisture surges, increasing showers and thunderstorms as they pass.
An Atlantic ridge is stretching over the southeast United States this morning. The high pressure will shift eastward tonight and weakens for the end of the work week.
Temperatures will remain fairly consistent with highs near 100 in the inland valleys and in the low 60s near the coast. Tonight northeast winds will increase over the ridges of Humboldt and Del Norte county.
The high pressure still anchored to our east should keep precip coverage minimal thus kept the mention of precip out both TAF sites at this time.
This stagnant weather pattern due in part to strong forcing aloft downstream of a stubborn trough of low pressure across Central Texas into Eastern Oklahoma and Southern Missouri.
Today Through Wednesday Night The pattern continues in the short term with an upper high pressure area over the southeast U. and an upper low over Arkansas.
Rain returns to the forecast Wednesday as the trough that pushed the front through this past weekend, gets cut off from the westerlies and begins to retrograde westward due to the influence of high pressure to the east.
This precipitation is most focused in the vicinity of a weak cold front which is currently approaching the I-57 corridor. The driving upper-level trof, at least the main energy within it, is pushing into west-central Illinois. The more substantial clouds/showers in SE IL will likely keep high temperatures in the 70s, but the remainder of the forecast area should see temperatures rebound to more normal levels in the lower 80s. Mostly quiet weather is expected tonight across the forecast area with weak surface ridging and neutral upper-level flow.
Water vapor loop indicated an upper trough over the area and will continue to move east. Forecast area goes into northwest flow aloft for a bit until next upper ridge axis moves over the area Wed afternoon. Water vapor loop indicate an upper trough/jet streak over BC. BC trough will move into central and southern Canada and amplify. A cold front will move out of Canada on Thu and produce threat for thunderstorms. The end of the work week and weekend will bring a period of mostly dry and cooler weather.
Afternoon highs in the lower to middle 90s are expected Today, except upper 80s along the coast.
850 mb temps again around 14C will support max temps mainly in the lower 80s inland under generally mostly cloudy skies. Expect mins ranging from the upper 50s interior west to the lower to mid 60s elsewhere.
740 AM EDT TUE AUG 16 2016 High pressure will extend across the area today.
Kept all zones dry through tonight (pop grids <15%), given high pressure building aloft with rising heights and anemic instability. This will translate to afternoon max temps a bit above mid August normals, in the low to mid 90s.
The computer models do suggest that the upper ridge will weaken somewhat over the weekend, allowing a weak front to dip down into our region. Overall south/southeast flow will continue in the lower levels for today but gradients are not tight and winds are not expected to be too strong, mainly 5-10 KTS.
As for high temperatures, near normal temps in the mid 80s for central/northeast MO while eastern portions of forecast area to remain cooler with highs only in the upper 70s to low 80s. Byrd Tonight weak surface ridging builds in with drier weather for at least the next 36 hours. Then as ridge moves off to the east, southerly flow returns to the region with increasing low level moisture and instability.
The net result is a more progressive movement of the mean southwest to northeast oriented low amplitude trough axis over the Northern U. The effective movement of the trough axis will still lead to a lingering chance of rain south and east of the Ohio River through Wednesday. The expansion of the Southeast ridge westward to the Lower Mississippi Valley and the movement of a ridge axis into the Desert Southwest and northern Mexico will impress the development of low to mid-level circulation in TX and AR, muddling the southeastward translation of moisture away from the WFO PAH forecast area.
An upper level ridge of high pressure will ensure warm and dry weather for today as high temperatures push well into the 80s to near 90 degrees. As the ridge axis slides east on Wednesday ahead of an approaching trough and surface cold front temperatures may even reach into the lower 90s for many areas.
Heights will build aloft today as a ridge axis shifts over the area. Temperatures are expected to be a couple degrees warmer than yesterday with highs in the low 90s in most places. Wednesday will be the warmest day of the week with high temperatures in the low to mid 90s expected.
629 AM PDT TUE AUG 16 2016 The high will move west by early Wednesday with temperatures above normal.
Similar to yesterday the moderate east-southeast flow may again negate or at least keep the west coast sea breeze very close to the coast where the highest pops and storm coverage should focus as the east coast sea breeze boundary marches westward and collides with the west coast boundary during the late afternoon and early evening hours. The high moisture content will favor some locally heavy rain with the storms along with frequent lightning strikes and gusty winds. East to southeast winds in the 10 to 15 knot range near shore and around 15 knots offshore with seas of 2 to 3 feet will continue across the Gulf waters into the afternoon as high pressure northeast of the waters remains in control.
This com- bined with the coastal trof/shear axis across the northern zones and the very low convective temps, we should continue to see the widespread development of moderate/heavy rains. Looking ahead, we should continue to see a very slow drop in PWs over the area as the upper ridge tries to build in from the east.
Upstream energy indicates warmer temperatures next 3+ days before pacific energy arrives with next cool front. partly sunny skies with light westerly winds will allow for highs several degrees warmer than yesterday. Mins a few degrees warmer than tonight in the 63 to 68 degree range or 2 to 4 degrees above normal.
PWATs are a bit lower today with some drier air aloft, while deeper moisture remains west of the area ahead of an upper-level trough and frontal boundary. Microburst parameters are in the low to low-end moderate category. Overall south/southeast flow will continue in the lower levels for today but gradients are not tight and winds are not expected to be too strong, mainly 5-10 KTS. The computer models do suggest that the upper ridge will weaken somewhat over the weekend, allowing a weak front to dip down into our region.
