238 PM CST Sat Nov 16 2019 A mid and upper level ridge has brought a pleasant day our way. Clouds will increase Sunday ahead of a decaying cold front that will move into the area Sunday night.
214 PM CST Sat Nov 16 2019 An upper trough is over the northern Rocky Mountains/northern plains states with an upper low extending south over the Pacific Ocean south of California. A cold front will begin moving into the area Sunday morning as the previously mentioned upper trough digs southward and moves over the central part of the country. The upper trough will move eastward over the Mississippi River with a cut off low remaining south of California.
1009 AM CST Sat Nov 16 2019 Only minor updates to hourly grids this morning, mainly to adjust for a slightly cooler start than forecast. /issued 526 AM CST Sat Nov 16 2019/ Looking at SKC skies as high pressure will continue to dominate the wx pattern over the weekend.
/issued 1047 AM CST Sat Nov 16 2019/ High pressure remains over the Mid-South this morning. At sunrise most of the region should be several degrees below freezing, mainly in the mid 20s. Warmer conditions are in store for the weekend and much of the upcoming work week.
Temperatures on Sunday will be mild with many lowland areas reaching the low to mid 50s.
However, cloud cover may continue to be an issue through tomorrow morning as some hi-res forecast soundings maintain a shallow layer of moisture at the low-levels.
The northern wave will send a cold front racing south tonight which should pass through the forecast area between about 2 am and 8 am Sunday morning.
Current upper level pattern is fairly zonal through the central plains with an upper level ridge moving through the southern plains. A trough is in the process of developing in the northern Rockies which will move into the area by later tonight. Tonight the upper level trough moves into western Kansas bringing a cold front. As the front moves through north winds will pick up 15-30 mph with post frontal stratus and the possibility of a few sprinkles of rain but not much in the way of organized precipitation due to the fact the lower levels will be moisture starved. Lows will range from the low 30s in the west to the upper 30s in the east. Cooler conditions on Sunday with an area of high pressure moving into the central plains and upper level winds staying in northwest flow.
A strong upper low moving off the Southeast coast is responsible for low-level cyclogenesis in the western Atlantic. Lows will fall into the low to mid 40s region-wide this evening, though cloud cover will remain in place, and possibly spread a bit further west.
/issued 1009 AM CST Sat Nov 16 2019/ Only minor updates to hourly grids this morning, mainly to adjust for a slightly cooler start than forecast.
258 PM CST Sat Nov 16 2019 At mid afternoon, a mid level trough was located from Manitoba into western New Mexico. Tonight the mid level trough will continue to move southeast into the central Plains with the trough axis moving across central and eastern Kansas Sunday morning. A cold front is expected to move southeast across the cwa tonight shifting the winds to the northwest and north. In addition some light rain is possible across far northeast Kansas as well as along and south of Interstate 35 where low level moisture will be the highest. A few of the CAMS are showing light precip chances through late morning Sunday across northeast and east central Kansas with the passage of the trough.
1015 AM CST Sat Nov 16 2019 Current forecast in good shape with warmer temperatures expected this afternoon as winds become more southerly.
A strong upper low continues to move off the Southeast coast. With nightfall it looks like some of the low clouds are building back westward again. With the clouds, lows will only fall into the low to mid 40s region- wide.
Short term forecast continues to be benign, with NW and then W flow aloft and high pressure at the SFC yielding another clear and cold night. Light freezing conditions are again expected across parts of East Central LA, with the rest of the area in the mid/upper 30s. Temperatures start to warm up tomorrow with afternoon highs reaching the lower/mid 60s, a little higher than today.
A cold front is currently moving through the Dakotas and is shifting winds to the northwest behind the front. Expect the 700mb trough and precipitation to continue to the east this evening and exit the area by late evening. 925-850mb moisture profiles and HREF cloud product show these low clouds remaining over most of the area through the night until a low level ridge moves through and shifts winds to the WSW from west to east on Sunday. The clouds and slightly cooler temps aloft will keep highs a little cooler on Sunday vs today.
Temperatures Sunday will be mild with many lowland areas reaching the low to mid 50s.
A warmer air mass is working its way into the region, and the mild start to the day has helped to bring high temperatures to above average readings. Snow levels will quickly rise tonight and all but the highest terrain will have rain. There is an outside chance for freezing rain Sunday morning mainly near Seeley Lake, Ovando, and Helmville, but confidence is low for temperatures to be at freezing once the rain starts.
415 PM CST Sat Nov 16 2019 High pressure will build in over the forecast area through mid week.
A cold front will move south across the area overnight with surface winds shifting from south to north behind the front. A trough will approach the area tonight and will move east of the southern Plains by midday Sunday.
As sunset approaches, the winds are forecast to weaken as mixing diminishes and the gradient begins to also slacken with the approach of the surface trof. Soundings indicate primarily rain with the low levels barely above freezing over the bottom few thousand feet.
245 PM MST Sat Nov 16 2019 A warmer airmass is working its way in to the region, and the mild start to the day has helped to bring high temperatures to above average. Snow levels will quickly rise tonight and all but the highest terrain will have rain. There is an outside chance for freezing rain Sunday morning mainly near Seeley Lake, Ovando, and Helmville, but confidence is low for temperatures to be at freezing once the rain starts.
/Issued 600 PM EST Sat Nov 16 2019/ Current radar loop shows a few showers lingering across east central GA as main low pressure center begins is way up the eastern seaboard. Clouds around the backside of the low are clearing the area from NW to SE. A weak ridge is beginning to build in over the area behind the exiting low pressure system which should keep things dry for the rest of the short term.
431 PM EST Sat Nov 16 2019 The latest surface map features high pressure centered near the Ontario/Quebec border, with ridging extending back towards the Great Lakes and down along the Mississippi River Valley. Meanwhile, dampening low pressure is shifting east across southern Saskatchewan, with an occluded/cold front extended south into the northern Plains and then southwest towards the front range of the Rockies. Aloft, a cutoff low continues to move east, away from the South Carolina coast, with a short wave trough moving towards the Plains. Short wave ridging is nosed in across the lower Mississippi and Tennessee valleys. The Plains short wave trough will dig and eventually become negatively tilted as it moves east southeast across the Midwest and the Mississippi Valley by the end of the period.
212 PM MST Sat Nov 16 2019 A weak surface front and trough aloft will pass over the northern CO mountains tonight. Some cold air will filter into northern and central CO to cool the high temperatures Sunday a few degrees. Sunday will see the ridge attempt to rebound back over the area but it will get pressured back to the south as a minor upper disturbance and jet max travel through the strong northwesterly flow aloft Sunday night.
740 PM EST Sat Nov 16 2019 Low pressure surface and aloft is located off the northeast Florida coast with a large area of cold air strato-cu in the wake of the system extending across much of the Florida peninsula. The area of low pressure will gradually lift away from the region tonight and Sunday. Cloudy skies will persist overnight, but as the area of low pressure moves away from the area, skies will clear early tomorrow morning with partly cloudy cool conditions expected on Sunday. to the lower 70s south.
Mostly clear skies as high pressure continues and generally light winds.
/Issued 246 PM EST Sat Nov 16 2019/ Current radar loop shows a few showers lingering across east central GA as main low pressure center begins is way up the eastern seaboard. Clouds around the backside of the low are clearing the area from NW to SE. A weak ridge is beginning to build in over the area behind the exiting low pressure system which should keep things dry for the rest of the short term.
A dry, light to moderate northerly flow will continue across the forecast area tonight and Sunday, as mid and upper level ridging builds east across the area in the wake of a developing low pressure area that will be heading up the mid Atlantic coast. Lows tonight will still be a little on the cool side, ranging from the lower 30s over northwestern interior counties to lower 40s southeast interior counties of the western Florida panhandle, especially north of I-10. Highs on sunday are expected to be in the low to mid 60s across the entire area.
In the wake of the Sunday night system, northwesterly flow will dominate at the surface, and despite it being warmer than Sunday, winds will be stronger. Highs are expected in the low 60s.
Cool and dry weather conditions will prevail throughout the weekend as mid to upper level high pressure ridge dominates the local area. Maximum temperatures will stay in the 60s area wide this afternoon and minimums will range in the upper 30s to low 40s tonight, warmer along the coastal regions. An increase in cloud coverage along with a warming trend expected Sunday, as high pressure gradually shifts eastward. Weather will remain quiet for the first half of the upcoming week as high pressure gradually works its way eastward.
A weak cold front will bring a wind shift from the N to NW to the Big Country (including KABI) around 15Z, then the Concho Valley/Heartland (including KSJT, KBBD) around 17-18Z, and the Northern Edwards Plateau and Northwest Hill Country (including KSOA, KJCT) around 18-19Z. /issued 237 PM CST Sat Nov 16 2019/ (Tonight and Sunday) Cooler temperatures are in store as a cold front will move across the region on Sunday. Otherwise, expect slightly cooler temperatures for tonight.
/Issued 238 PM CST Sat Nov 16 2019/ A mid and upper level ridge has brought a pleasant day our way. Clouds will increase Sunday ahead of a decaying cold front that will move into the area Sunday night.
High pressure will continue to build over the region, allowing winds to lighten and VFR conditions to prevail. /issued 201 PM CST Sat Nov 16 2019/ SHORT TERM (Now through Sunday Night): High pressure heads east through the period with a very weak frontal boundary and northerly wind shift approaching Deep South Texas and the Rio Grande Valley Sunday night. Light and somewhat variable winds overnight shifting southeast may still allow temperatures to dip into the low 50s or upper 40s north and mid to upper 50s across the RGV.
Temperatures have fallen into the low 40s and upper 30s.
The high moving to the east was slowing normally quick NE movement of a storm east of GA/SC border. Unlike yesterday when lagging upper level portions of this system brought clouds and rain to areas mainly to our south, this low has become more vertically stacked, with most of its associated clouds and precipitation closer to the system. Otherwise, afternoon temperatures will climb a few degrees warmer than today to near 60. With increased cloud cover, temperatures overnight remain above freezing Sunday night.
A cold front early tomorrow morning will shift winds to the north with gusts increasing to 20-25kt sustained. /issued 214 PM CST Sat Nov 16 2019/ An upper trough is over the northern Rocky Mountains/northern plains states with an upper low extending south over the Pacific Ocean south of California. A cold front will begin moving into the area Sunday morning as the previously mentioned upper trough digs southward and moves over the central part of the country. The upper trough will move eastward over the Mississippi River with a cut off low remaining south of California.
713 PM EST Sat Nov 16 2019 High pressure to the northeast will bring continued dry and cool conditions into Sunday.
At mid afternoon, a mid level trough was located from Manitoba into western New Mexico. Tonight the mid level trough will continue to move southeast into the central Plains with the trough axis moving across central and eastern Kansas Sunday morning. A cold front is expected to move southeast across the cwa tonight shifting the winds to the northwest and north. In addition some light rain is possible across far northeast Kansas as well as along and south of Interstate 35 where low level moisture will be the highest. A few of the CAMS are showing light precip chances through late morning Sunday across northeast and east central Kansas with the passage of the trough.
439 PM MST Sat Nov 16 2019 A weak surface front and trough aloft will pass over the northern CO mountains tonight. Some cold air will filter into northern and central CO to cool the high temperatures Sunday a few degrees. Sunday will see the ridge attempt to rebound back over the area but it will get pressured back to the south as a minor upper disturbance and jet max travel through the strong northwesterly flow aloft Sunday night.
Although the thermodynamic profile overnight appears favorable for a lee mountain wave event amid llvl southeasterly flow ovr the ridges, the balance between strong stability and wind speed does not appear to be ideal with expected Froude number below 1. As a result, the strength of the inversion above ridge top may be too great for the wind to overcome, thus suppressing vertical propagation of mountain waves and limiting stronger wind to the ridge tops. Flow aloft will transition to sely on Sun/Mon ahead of a trough amplifying in the nrn Plains. As a result, precipitation type (if any occurs) could be light snow, drizzle/freezing drizzle, rain or a time-varying combination of all. VFR will prevail throughout this period as high pressure builds to our northeast.
IR imagery this evening showing thin cirrus continues to invade our region from the west and northwest ahead of a longwave trough that is currently moving out of the Intermountain West and expected to move into the Great Plains overnight. There will be a frontal boundary associated with the longwave trough axis that will begin moving into our northwest airspace Sun Aftn and should push through our entire airspace by Sunday Night.
Weak cold front will begin moving into our airspace from the north and west during the day Sunday with little fan fare. Cannot rule out a weak cu field across our western airspace during the day Sunday in association with the cold front.
107 AM EST Sun Nov 17 2019 High pressure will extend across the region today.
920 PM MST Sat Nov 16 2019 High pressure aloft will return for early in the upcoming week, followed by a Pacific storm system impacting mainly central and southern Utah midweek.
230 AM CST Sun Nov 17 2019 Scattered midlevel clouds have moved in behind the cold front that pushed through yesterday afternoon and evening. Skies should become mostly clear this morning, but highs are only expected to reach the 50s in this cooler airmass.
A cold front will move through early in the morning, shifting winds to the north with gusts increasing to 20-25kt sustained. /issued 214 PM CST Sat Nov 16 2019/ An upper trough is over the northern Rocky Mountains/northern plains states with an upper low extending south over the Pacific Ocean south of California. A cold front will begin moving into the area Sunday morning as the previously mentioned upper trough digs southward and moves over the central part of the country. The upper trough will move eastward over the Mississippi River with a cut off low remaining south of California.
900 PM MST Sat Nov 16 2019 NW winds have diminished for the most part this evening as upper trough moves to the east. High pressure will be over the area overnight. Forrester Previous Forecast Discussion: Morning cold front and upper trough have moved to our east this afternoon with an upper ridge moving in from the Pacific NW.
Latest observations and satellite imagery show mostly clear skies as high pressure at the surface remains in control. As the trough across the plains pivots southeastward, this will strengthen ridging across the region. High temperatures today will be similar if not a degree or two warmer than Saturday with highs ranging from the low 50s to low 60s. Ridging aloft will be short lived as height falls accompanying the upstream trough begin to move overhead. At the surface, a weak cold front will progress through the Mississippi and Ohio valley Sunday night. Near climatological temperatures can be expected on Sunday night with lows in the low to upper 30s across the area.
coast will continue to drift away from the area today with weak high pressure building in from the northwest. The low clouds will gradually thin out and lift during this morning with partly to mostly sunny skies expected this afternoon. The next mid/upper level trough and associated short wave energy will move into the eastern U.
251 AM CST Sun Nov 17 2019 Today's cold front is pretty much on track cutting southwest to northeast from Morton to Plainview to Memphis and will continue to move southward through these early morning hours.
156 AM EST Sun Nov 17 2019 Weak systems early in the week give way to high pressure mid week. Despite a chilly start, afternoon highs will be mainly in the mid 50s for the lowlands and upper 30s to mid 40s for the mountains as low level flow turns more southeasterly in response to weakening influence of the coastal storm off the Carolinas and increasing influence of trough over the Midwest.
However, there is a scenario where surface temps dip just below freezing in spots. Given that saturation will not be deep/cold enough to support ice crystals for snow technically we could see drizzle/freezing drizzle too. Wouldn't expect any issues if freezing drizzle did occur because road temps would be too warm, precip will be very light and short-lived.
High pressure aloft will build into the area through Sunday for dry conditions most areas. Temperatures will be a few degrees warmer.
Mostly cloudy skies this morning will give way to partly cloudy skies as the large upper level low centered to our east moves out of the region. High temperatures will be slightly warmer in our eastern zones as the lower level clouds that kept temperatures in the mid 50s move out today.
1038 PM MST Sat Nov 16 2019 A weak surface front and trough aloft will pass over the northern CO mountains tonight. Some cold air will filter into northern and central CO to cool the high temperatures Sunday a few degrees. Sunday will see the ridge attempt to rebound back over the area but it will get pressured back to the south as a minor upper disturbance and jet max travel through the strong northwesterly flow aloft Sunday night.

A cold front will move south across the area overnight with surface winds shifting from south to north behind the front. A trough will approach the area tonight and will move east of the southern Plains by midday Sunday.
1051 PM EST Sat Nov 16 2019 High pressure will extend across the region into Sunday.
A cold front is past HOB and CNM and will reach remaining TAF sites between 12-14Z. /issued 340 AM CST Sun Nov 17 2019/ Our next cold front is now making its way through the TX Panhandle and should arrive in our area over the next few hours. Temperatures this afternoon will be slightly cooler with highs mostly in the 60's across the area.
and Monday Low level warm advection and the approach of an upper trough will combine to produce some light precipitation today. The precipitation could end as scattered drizzle or freezing drizzle this evening. Wet roads and sidewalks could get slick as temperatures fall below freezing. Monday should be mostly cloudy and a little colder than normal as weak high pressure moves into the region.
With the associated ridge axis moving on shore, height gradients are tightening and a westerly flow is setting up across the Treasure State. Ridgetop winds across the Northern Rockies may exceed 60 mph.
340 AM CST Sun Nov 17 2019 Our next cold front is now making its way through the TX Panhandle and should arrive in our area over the next few hours. Temperatures this afternoon will be slightly cooler with highs mostly in the 60's across the area.
A cold front will cause winds to shift out of the north and increase to 10-15 KTS by early afternoon. A cold front was located across the Panhandle and moving southward. By tonight, high pressure will settle in across west Texas, bringing slightly drier air with it.
A cold front/wind shift will progress across the area and post-frontal gusts up to 20-25 knots will be possible through the day at most sites. /issued 303 AM CST Sun Nov 17 2019/ Progressive trough will continue to pass over and just north of Oklahoma today. However, main impact of this trough will be a weak frontal boundary.
/issued 338 AM EST Sun Nov 17 2019/ As the strengthening low pressure off the Carolina Coast pushes further away from the region on Monday, a weakening the pressure gradient will allow surface winds to relax.
A weak cold front will push into the area overnight. High pressure will shift further to the east as an upper level trough and associated weak surface boundary move through Texas.
303 AM CST Sun Nov 17 2019 Progressive trough will continue to pass over and just north of Oklahoma today. However, main impact of this trough will be a weak frontal boundary.
248 AM MST Sun Nov 17 2019 A cold front is expected to move through the region this evening, bringing up winds. Cold front, currently near the Wyoming and Colorado border will sweep south through the area during the late afternoon and early evening. High temps tomorrow will be cooler than today, in the mid 50s at most locations with generally light winds.
As of 09Z Sunday morning, a neutrally tilted midlevel trough was positioned across the Central and Northern Plains. Skies will clear quickly by late morning as the midlevel trough progresses eastward, setting the stage for a pleasant fall day. Surface ridging will traverse the CWA overnight, shifting winds from the northwest to the southwest at 5-10 kt. In the wake of the midlevel trough that is currently traversing the CWA, northwest midlevel flow will ensue by Monday.
The main talking point for Monday is when a low moves through with a well defined cold front.
Trough axis shifts east of the forecast area during the day Monday.
A cold front was located across the Panhandle and moving southward. By tonight, high pressure will settle in across west Texas, bringing slightly drier air with it.
