Mid/high cloudiness will continue to increase, and thicken especially tonight as the upper level trough swings through the region. However, overnight into early Tuesday morning cold advection in wake of cold front may be sufficient to lower saturation enough for some flurries, especially from around Quad Cities north and east where some vorticity advection and upper level diffluence nearby. In general the pattern looks to turn rather active by the end of the week and could remain so for at least the next couple of weeks, as models want to place the region in/near the mid level baroclinic zone between cold trough in the west and warm ridging in the southeast with SW flow aloft.
521 AM CST Mon Jan 6 2020 A quiet Monday is expected with mostly sunny skies as an upper level ridge sits over the region. An upper level trough will swing through the region Tuesday night, bringing increasing clouds and chances for light snow. A cold front will move through Tuesday morning, and this will cause Tuesday's high temperatures to occur during the morning hours, with temperatures cooling down through the day.
437 AM CST Mon Jan 6 2020 A quiet Monday is expected with mostly sunny skies as an upper level ridge sits over the region. An upper level trough will swing through the region Tuesday night, bringing increasing clouds and chances for light snow. A cold front will move through Tuesday morning, and this will cause Tuesday's high temperatures to occur during the morning hours, with temperatures cooling down through the day.

High pressure will bring a couple days of quiet weather.
947 AM EST Mon Jan 6 2020 With high pressure in place over the forecast area this morning, the short-term forecast remains in good shape. Temperatures should remain warm enough for all liquid precipitation with this system, although I can't rule some brief mixed precipitation at the highest elevations at the onset and the exit of the precipitation.
Behind the upper trough 850mb winds will increase to 40-50kts in the region of strongest cold advection aloft over northwestern South Dakota. Cold high pressure will drop southward into the central and eastern Dakotas tonight and on Tuesday. Late this week into the weekend, a broad deep upper trough will drop develop, aiding the southward surge of much colder air into the northern plains. Winds should decrease by 00z, then gradually increase again out of the W/SW through the remainder of the TAF period as the next trof approaches.
Surface analysis showing high pressure centered over the north central Gulf, and low pressure and an accompanying NE-SW oriented cold front extending across NE Louisiana and through central Texas. Partly to mostly sunny skies expected with temperatures well above the norm warming into the low 70s as light south to southwest winds continue. Cooler temperatures returning. Feature will be sufficient to punch the cold front to our north and west across the region overnight.
High pressure over the area will provide sunny skies and light winds. Temperatures tonight will not be quite as cool with readings mostly in the lower 40s.
912 AM EST Mon Jan 6 2020 High pressure will extend across the region into tonight. A mostly rain-free cold front will push through Tuesday with high pressure returning through the middle of the week. Dry high pressure will prevail this period, except on Tuesday when a mostly dry cold front will move through.
A cold front will move through the area today. /issued 348 AM CST Mon Jan 6 2020/ (Today and Tonight) A weak upper level trough will swing across the Plains today into tonight. This will result in a cold front moving into the Big Country late this morning and through the rest of the area this afternoon. Mild temperatures are forecast ahead of the front, with afternoon highs in the low to mid 60s across the Big Country to the upper 60s to mid 70s across the rest of the area.
Broad upper ridging is aiding in mainly clear skies across the region, with the exception of interior valleys, where antecedent ground moisture was supporting patchy fog. Clouds will then increase tonight ahead of an approaching upper trough. That trough will lead to widespread frontal rains by Tuesday afternoon, which is forecast to transition to post-frontal showers during Tuesday evening.
348 AM CST Mon Jan 6 2020 (Today and Tonight) A weak upper level trough will swing across the Plains today into tonight. This will result in a cold front moving into the Big Country late this morning and through the rest of the area this afternoon. Mild temperatures are forecast ahead of the front, with afternoon highs in the low to mid 60s across the Big Country to the upper 60s to mid 70s across the rest of the area.
Snow continues to fall on the Cascade Crest with radar now blooming some over the high terrain of the Blue Mtns as well. Satellite trends and model data might suggest a warm front is beginning to develop; this feature will pass north through the region today. Next impulse in the generally westerly flow comes tomorrow with a slight uptick in Washington Cascade snow and better chances for Oregon Cascade snow and a dusting in the highlands of Central OR.
Strong high pressure centered over the north central/northeast GOMEX will maintain a light N/NW breeze thru midday. As the ridge center drifts overhead and collapses the pgrad, a weak seabreeze will dvlp with winds shifting to NE blo 10mph. Favorable boating conditions as high pressure centered over the nrn GOMEX builds east and collapses the sfc pgrad.
We now have filled in the I-70 corridor east to Glenwood Springs and the Highway 50 corridor south through Delta, Montrose and Ridgway. Also expect gusty conditions along the ridges in fast NW flow with speeds up to 40 mph. Low clouds and patchy fog will likely redevelop across the lower valleys overnight. Temperatures will be challenging as the low stratus deck and strongly inverted valleys are resulting in high temps from 10 to 15 degrees below normal. Flat ridging will slip east of the divide Tuesday night with strengthening southwest flow setting up across the forecast area. Some hope that this will help break up the strongly inverted valleys and allow the low cloud decks to erode out.
Despite the passage of a open midlevel trof and associated surface cold front this evening, temps will cool only slightly on Tuesday, relative to today.
436 AM EST Mon Jan 6 2020 High pressure will build into the region briefly and bring dry weather today with temperatures above normal near 40. A weak trof may be accompanied by sprinkles or flurries Tuesday, but any amounts will be very light.
Westerly winds, subtle WAA and sunny skies should allow temperatures to warm back into the low 50s during the afternoon.
334 AM CST Mon Jan 6 2020 An upper trough remains over the region today bringing some clouds to the area. At the sfc, weak low pressure will have limited effect today. Canadian high pressure drops in on Tuesday which will cause highs to drop closer to average in the teens and 20s.

Ridging will once again build to our west on Tuesday, placing us back in a northwest flow regime aloft. At the surface, cold high pressure will scoot from the Canadian Prairies Tuesday afternoon to the Red River Valley in eastern North Dakota by the overnight hours.
933 AM EST Mon Jan 6 2020 Dry high pressure will be in control today. A cold front with limited moisture will cross the area Tuesday. The region will be under dry zonal flow today with continued surface ridging. Most of the moisture and energy associated with this disturbance is forecast to remain north of the area, and low-level moisture will remain limited with h85 westerly flow following the quick passage of a weak cold front. The highest chances will be in the north closer to greater upper lift and moisture. Temperatures will then drop to near freezing Tuesday night with diminishing winds and clearing skies.
607 AM EST Mon Jan 6 2020 High pressure will build into the region briefly and bring dry weather today with temperatures above normal near 40. A weak trof may be accompanied by sprinkles or flurries Tuesday, but any amounts will be very light.
Then expect increasing potential for clouds by this afternoon, although still expected to be VFR conditions until after 00Z when some -SHRA and MVFR ceilings will be possible as a weak cold front moves west to east across the region. Highs today will be warmer - mid 60s to near 70 - south of the front, and then the low will kick the cold front through with temperatures falling into the 30s and 40s tonight behind it.
536 AM CST Mon Jan 6 2020 High pressure was centered near St. Still expect the forecast to remain dry as atmosphere over the area is very dry, so the trough will not bring much more than mostly cloudy skies this afternoon and tonight.
The offshore flow will bring warmer high temperatures today, especially for coastal and western valley areas.
A cold front will sweep through Central California Tuesday night. Most, if not all, precipitation associated with this cold front will remain north of the forecast area.
906 AM EST Mon Jan 6 2020 Dry high pressure will be in control today. A cold front with limited moisture will cross the area Tuesday. The region will be under dry zonal flow today with continued surface ridging.

The highest chances will be in the north closer to greater upper lift and moisture. Temperatures will then drop to near freezing Tuesday night with diminishing winds and clearing skies.
532 AM CST Mon Jan 6 2020 VFR will dominate while a cold front passes mid to late this morning. Guidance has been consistent, with good consensus, that the longwave pattern will result in several progressive troughs passing across our region with requisite ridging in between. The forecast is mostly dry, with a slight chance of POPS late in the week as an upper low tries to squeeze meager QPF out of a mostly continentally modified moisture source.
645 AM EST Mon Jan 6 2020 Under clear skies and northeast winds ranging from 10 to 18 mph, temperatures vary from the upper 50s in portions of the Upper Keys to the lower to mid 60s elsewhere, Meanwhile, local radars are void of any precipitation echoes.
Have added high clouds late in the period at DHN/ABY to indicate an increase in higher moisture aloft from an upstream low pressure system.
A quiet Monday is expected with mostly sunny skies as an upper level ridge sits over the region. An upper level trough will swing through the region Tuesday night, bringing increasing clouds and chances for light snow.

1251 PM EST Mon Jan 6 2020 Expect mostly clear skies today and tonight as high pressure settles over the region.
1247 PM CST Mon Jan 6 2020 Made some minor tweaks to the hourlies and the high for today, otherwise no major changes to the forecast at this time. An upper trough remains over the region today bringing some clouds to the area. At the sfc, weak low pressure will have limited effect today. Canadian high pressure drops in on Tuesday which will cause highs to drop closer to average in the teens and 20s.
Light NNW winds this afternoon will become WSW and increase to 10-15 knots after 14z Tuesday ahead of a dry cold front. High pressure over the area will provide sunny skies and light winds. Temperatures tonight will not be quite as cool with readings mostly in the lower 40s.
1227 PM CST Mon Jan 6 2020 Made a few tweaks to temps as our usual cold spots are running a bit lower than the higher terrain just west and east of the Red River Valley. High clouds will begin working back into the area this afternoon in advance of our next cold front. For today, look for quiet weather ahead of the next cold front that will traverse the region tonight. Breezy northwest winds are expected for the higher elevations west of the Red River Valley with 20 to 25 mph sustained winds and occasional gusts to near 35 mph as the front passes through.
115 PM EST Mon Jan 6 2020 Dry high pressure will be in control today. A cold front with limited moisture will cross the area Tuesday. High pressure continues to hold over the area which will keep skies clear through this evening. Most of the moisture and energy associated with this disturbance is forecast to remain north of the area, and low-level moisture will remain limited with h85 westerly flow following the quick passage of a weak cold front. The highest chances will be in the north closer to greater upper lift and moisture. Temperatures will then drop to near freezing Tuesday night with diminishing winds and clearing skies.
Surface observations show the cold front is infringing on the northern portion of the County Warning Area, stretching from a Del Rio to Blanco to Pflugerville line. A cooler and drier air mass will filter in behind the front with high temperatures Tuesday afternoon being 8 to 10 degrees cooler than Monday's highs for most sites. Dewpoints Tuesday afternoon will be in the lower teens with north winds nearing 10 mph for most of the region.
This trough will reinforce a stationary sfc bndry along the I-30 corridor of NE TX/SW AR SE as a cold front by mid to late afternoon, reinforcing slightly cooler but drier air SE in its wake as it exits the region around 06Z.
244 PM CST Mon Jan 6 2020 Low-level water vapor imagery and 850 mb heights depict two separate/disjointed short wave troughs moving across the Northern Plains. In the wake of passing trough and associated surface cold front, expect colder temperatures /closer to normal/ for Tuesday night.

TFJ Overrunning snow event is expected to develop tonight with the merger of the lee trof with an arctic boundary over central Montana. By this evening the front will settle across central and southern Montana with Canadian high pressure nosing into the northern Plains. Upper ridge will be building over the west coast, with moisture streaming around the top of the ridge. Pattern is fairly progressive so as next trof approaches the west coast on Tuesday, the upper ridge will be pushed east into the northern Rockies. The snow band will begin to lift across northeast Montana by Tuesday afternoon, but with the amplifying ridge, the better dynamics shift north with highest snow amounts expected near the Canadian border into Tuesday night.
137 PM CST Mon Jan 6 2020 High pressure is moving east of the region today, allowing a trof to move through Nebraska into Iowa. This trof is going to be absorbed into a seasonally strong cold front today, as the front moves through the Dakotas. Tonight, the cloud cover should tend to be opaque through the evening, allowing for temperatures to hold in the lower 30s. Saturation on the upcoming trof looks to be more limited over eastern Iowa this evening, and with models showing the convergence on that trof decaying as the cold front approaches, I feel we'll be seeing a dry evening, with snow showers dissipating before entering our area. A seasonally cool night is forecast Tuesday night, with lows in the lower teens north to lower 20s south.
GFS and ECMWF both show some light QPF into southern portions of west Kentucky for late this evening into the overnight hours, with dry conditions returning by 12z as the low quickly shifts northeast.
1134 AM CST Mon Jan 6 2020 Winds have increased behind a cold front at all TAF sites late this morning. Guidance has been consistent, with good consensus, that the longwave pattern will result in several progressive troughs passing across our region with requisite ridging in between. The forecast is mostly dry, with a slight chance of POPS late in the week as an upper low tries to squeeze meager QPF out of a mostly continentally modified moisture source.
In response to the first system, a cold front (currently over central Texas per MSAS) is expected to move SWD across the CWA tonight/early Tuesday. Drier and cooler Tuesday. Expect lows Tuesday night in the upper 30s to the lower 40s over the CWA.
VFR conditions expected during the period, except for brief MVFR ceilings possible over the Coastal Plains ahead of and along the cold front as it moves across South Texas, approximately during the 04-09z Tuesday period. Following some fog early this morning over the eastern half of the region, few forecast challenges exist today underneath weak zonal flow and mild southerlies in the low levels. Highs tomorrow will only cool to near normal values for most areas as surface ridging expands south.
245 PM CST Mon Jan 6 2020 WV imagery shows a weakly-amplified upper-level trough moving thru West Texas and Southeast New Mexico this afternoon, w/zonal-to-SW flow aloft over the region. As a result, highs will be a few degrees cooler Tue, although still above-normal under NW flow aloft. Meanwhile, a secondary trough will be making landfall on the west coast, and will pass the Four Corners by 00Z Thu, transitioning flow aloft to SW, and adding a couple of degrees to Tuesday's highs.
/Issued 947 AM EST Mon Jan 6 2020/ With high pressure in place over the forecast area this morning, the short-term forecast remains in good shape. Temperatures should remain warm enough for all liquid precipitation with this system, although I can't rule some brief mixed precipitation at the highest elevations at the onset and the exit of the precipitation.
A weakening front will arrive from the north on Tuesday, as high pressure centered over Texas migrates eastward and bridges across the eastern Gulf.
251 PM CST Mon Jan 6 2020 Southwest winds at the surface keep our temperatures mild today, but will transition out of the northwest this evening as a weak cold front pushes through the region. Low temps tonight are expected in the low teens and highs for tomorrow in the upper teens to mid 20s.
