1229 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. 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.
223 PM CST Mon Jan 6 2020 High pressure is already being pushed off to the northeast as a center of low pressure quickly develops over northern Mississippi. This low center will race across Middle Tennessee overnight while also showing some signs of frontogenesis before the system exits the mid state Tuesday morning.
West to southwest winds were ahead of the trough, while behind (west) of the trough northwest winds were gusting to 35 to 45 mph. Winds will decrease gradually this evening across the area, but then a trailing cold front enters northwestern ND late this evening/tonight and sweeps southeast across the state.
Most locations will have freezing temperatures tonight, before a warming trend begins Tuesday. This, along with clear skies, will help produce overnight lows just below the freezing mark again tonight, for most areas.
Elsewhere expecting lows to be in generally in the lower 20s. This will push a cold front into portions of north central Nebraska during the afternoon.
High pressure ridge will be overhead through Tonight.
118 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.
1249 PM EST Mon Jan 6 2020 High pressure will briefly build into the region today before a system passes mainly to the south of the area tonight into Tuesday.
Warm front lifting through the area today will keep a steady light to moderate snow over the mountains of Baker county and west-central Idaho. The lower Snake Plain up to the Baker Valley will see periods of light rain or snow showers today with any light accumulation limited to the Weiser basin and higher areas along I-84 in Baker county.
1133 AM CST Mon Jan 6 2020 /18Z TAFS/ Southwest to west winds generally less than 10 KTS early this afternoon become northwest to north 12-15KT with gusts to 20 KTS mid to late afternoon as a cold front moves 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.
Winds will shift from southwest to northwest by the afternoon and evening which will allow cooler air to filter in.
1125 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.
1111 AM CST Mon Jan 6 2020 High pressure over the central Mississippi Valley will bring dry conditions to the area through tonight. A dry cold front will move through the region on Tuesday before high pressure builds back into the Midwest for midweek.
VFR conditions are expected to continue through the period, although sky cover will gradually increase from SCT to BKN by late aftn/early evening ahead of a weak cold front.
/issued 710 AM EST Mon Jan 6 2020/ Latest RAP model shows sprawling deep layer ridging easing east across the Gulf of Mexico today. High pressure in the Gulf keeps winds north or northeast at 10 knots or less with seas no more than 3 feet today.
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.
tomorrow should be dry and slightly cooler, with highs in the low to middle 50s. Latest surface analysis places a weak area of low pressure near over northwest Mississippi, with a warm front strewn across north Mississippi and a trailing cold front parallel to the Mississippi River. High pressure will build in behind the front on Tuesday, with temperatures slightly cooler than the past few days. Expect highs in the low to mid 50s under sunny skies.
548 PM CST Mon Jan 6 2020 VFR conditions will remain for the entire TAF period as some of the higher cloud decks make their way out of the area.
425 PM MST Mon Jan 6 2020 The sun shone slightly more today across eastern Utah and western Colorado with the Grand Junction area sitting several degrees above yesterday's high with the Moab area climbing to a degree or two warmer. However, the inversions are still holding strong as both the aforementioned areas remain below freezing and close to ten degrees below normal. Temperatures and pinning down the location of where the low clouds will persist remain the primary forecast challenge in the short term. Given that high pressure will begin to slide over the area late tonight and into Tuesday, confidence is low that this trend will continue.
226 PM MST Mon Jan 6 2020 Current surface map places trof across the central Dakotas with cold front in southern Alberta/Manitoba. Cold front across southern Canada slips into the North Dakota backs into the area tonight. A bit of light snow possible along the low level baroclinic zone late tonight/early Tuesday.

High pressure is already being pushed off to the northeast as a center of low pressure quickly develops over northern Mississippi. This low center will race across Middle Tennessee overnight while also showing some signs of frontogenesis before the system exits the mid state Tuesday morning.
Latest surface analysis places a weak area of low pressure near over northwest Mississippi, with a warm front strewn across north Mississippi and a trailing cold front parallel to the Mississippi River. High pressure will build in behind the front on Tuesday, with temperatures slightly cooler than the past few days. Expect highs in the low to mid 50s under sunny skies.
254 PM MST Mon Jan 6 2020 The main change to the forecast was to add the potential for freezing rain tonight. The high terrain and mountain passes are expected to have moderate, with periods of heavy snow, through tonight. Valley locations in northwest Montana are stable enough that snow will maintain through at least the evening, while the lower valleys of north-central Idaho and west-central Montana are seeing down-sloping effects and less precipitation. Snow changing to freezing rain and rain will create travel difficulties through Tuesday morning. Winter Weather Advisories have been expanded to include additional snow in the valleys of northwest Montana and include the potential for freezing rain.
//00Z TAFS// Cold front currently moving SE through the Hill Country should be to the I-35 terminals between 01Z and 03Z. 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.
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.
756 PM EST Mon Jan 6 2020 High pressure will remain in control just south of the region tonight with mainly clear skies/light SW flow and another night of seasonably cool temps with lows in the upper 30s/near 40 inland and lower to middle 40s closer to the coast. On Tuesday dry cold frontal passage expected during the early afternoon hours and the W-SW flow ahead of the front should push Max Temps to around 70 degrees area-wide. High pressure ridge will be overhead through Tonight.
818 PM EST Mon Jan 6 2020 A low pressure is expected to bring a quick round of snow south and east of Pittsburgh Tuesday.
