536 AM CST Sun Jan 5 2020 Gusty northwest winds early this morning with the highest of 52 mph measured at KVTN ASOS at 153 am CST. Weak cold air advection will limit daytime highs today to near 40 nctrl and the lower 40s southwest. Lows tonight mainly in the lower 20s. Another cold front will move in during the morning, with the strongest winds in the afternoon.
A cold front will move through the area today. /issued 310 AM CST Sun Jan 5 2020/ (Today and Tonight) A weak cold front will move through the Big Country this morning, reaching the Interstate 10 corridor by late afternoon, before washing out this evening. Highs this afternoon behind the front will be in the low to mid 60s across the northern half of the area and in the upper 60s to lower 70s across the southern half of the area. Overnight lows will be in the low to mid 30s for most locations. One trough will move across the central U.
Slight ridging for the first part of the next work week before the upper jet gets more active. From there attention is on the long wave trough which is progged to dig south across the western CONUS by midweek.
A dry cold front brings cooler weather back to the area on Monday, with a stronger system possible later in the week. Temperatures will drop back down to near normal values Monday as a dry cold front moves across the area Monday morning.
16 inches!) and stable conditions via 12Z raob data courtesy of high pressure building in will support very cool dry conditions across the entire forecast area the remainder of today with ample sunshine expected.
955 AM EST Sun Jan 5 2020 High pressure will continue building across the area today.
An upper level ridge builds over our area today. An upper level trough traversing the Northern Plains will send a weak cold front toward our area late this afternoon into evening. Its only impact will be compressional heating to bring warmer high temperatures this afternoon, and a wind shift to maintain the dry airmass across the Edwards Plateau, Hill Country, and our Central Texas counties tonight. An upper level trough currently moving onshore the Pacific Northwest will move across the Plains on Monday. This will send a cold front into the Edwards Plateau late Monday afternoon and across the remainder of our area Monday evening.
428 AM CST Sun Jan 5 2020 Quick update to adjust temperatures upward within and east of the valley along the warm front. Warmer air aloft was able to mix to the surface within the valley. RAP and SPC mesoanalysis indicates a narrow corridor of strong 925mb cold air advection across eastern North Dakota (along the cold front). System across southern Canada has a warm front currently (09z) near the Red River Valley, with a cold front just entering eastern North Dakota. The thermal ridge will propagate through the region this morning, and gusty west winds are mixing warmer air aloft to the surface allowing temperatures to reach near 40F along and behind the warm front. For tonight into Monday, brief ridging tonight followed by a similar, but weaker system on Monday.

415 AM CST Sun Jan 5 2020 A weak cold front will move through the area early this morning, shifting winds to the northwest. With ample sunshine and decent PBL mixing, I have opted to go with the warm side of guidance for highs today and have temperatures in the low 50s in east-central KS and near 50 degrees elsewhere. Conditions will be a little cooler to start the workweek due to increased cloud cover and lighter winds, but the pattern stays fairly settled until midweek.
550 AM EST Sun Jan 5 2020 High pressure will extend across the region through Monday.
A Pacific cold front will enter northwest NM aft 06Z tonight with breezy northwest winds through Monday afternoon. High temperatures will remain a few to around 10 degrees above normal today, despite some cooling with a back door cold front across eastern New Mexico. A Pacific cold front will cross from the northwest Sunday night causing high temperatures to fall near and below normal across northern, central and western areas on Monday.
339 AM CST Sun Jan 5 2020 Gusty northwest winds early this morning with the highest of 52 mph measured at KVTN ASOS at 153 am CST. Weak cold air advection will limit daytime highs today to near 40 nctrl and the lower 40s southwest. Lows tonight mainly in the lower 20s. Another cold front will move in during the morning, with the strongest winds in the afternoon.
Temperatures and dew points are also hovering near freezing, so frost can be expected through the morning as well. Temperatures will quickly warm as the sun comes up, and the return of southerly winds will result in warmer temperatures tonight mostly in the 40s. Some patchy fog may be possible again, as warmer and more humid air moves in. High pressure then begins to build back into the southeast, and mild weather will continue through mid week with high temperatures on a slow climb.
Accumulations should be relatively light in the valleys with the potential of an inch in the higher terrain. On Monday, the nose of a jet streak will be on top of the Northern Rockies causing gusty westerly winds, especially in the higher terrain. This disturbance will also begin a period of fairly steady moderate snow for the higher terrain along the Montana/Idaho border and up into northwest Montana.

Conditions will be a little cooler to start the workweek due to increased cloud cover and lighter winds, but the pattern stays fairly settled until midweek.
Yesterdays passing sharp upper trough now well east. but incoming upper ridge will weaken rapidly as next upper trough already expected to pass early Tue. Wed/most of Thu setting up with dry conditions as SFC/LL highs and upper ridges work across the region. Both models show a deep upper trough coming out of the desert southwest by early Sat but GFS remains more aggressive moving this trough east. This brings a warm front and another round of pcpn to the area Mon/Mon night. ending early Tue when a cold front swings across.

1022 AM EST Sun Jan 5 2020 High pressure will extend across the region through Monday.
/15/ Strong high pressure ridging prevails across the ArkLaMiss and this will continue through the day. Clear skies will also continue, with high temperatures climbing into the low to mid 60s. Bumped up highs this afternoon a couple of degrees as guidance has come in a touch warmer, but other than that the forecast is on track. Temperatures and dew points are also hovering near freezing, so frost can be expected through the morning as well. Temperatures will quickly warm as the sun comes up, and the return of southerly winds will result in warmer temperatures tonight mostly in the 40s. Some patchy fog may be possible again, as warmer and more humid air moves in. High pressure then begins to build back into the southeast, and mild weather will continue through mid week with high temperatures on a slow climb.
Gusty winds this morning will weaken as high pressure takes over the lower Missouri valley.
Sites below 4k feet that have accumulated snow will see most of it melt off this afternoon as temperatures warm above freezing.

Early afternoon surface map indicated the surface trof was pushing through central IL, accompanied by gusty west winds. This ridge will track east, and stretch across the area on Monday. The result will be much lighter winds and cooler but still above normal temperatures in the upper 30s to mid 40s.
Strong high pressure ridging prevails across the ArkLaMiss and this will continue through the day. Clear skies will also continue, with high temperatures climbing into the low to mid 60s. Bumped up highs this afternoon a couple of degrees as guidance has come in a touch warmer, but other than that the forecast is on track. Temperatures and dew points are also hovering near freezing, so frost can be expected through the morning as well. Temperatures will quickly warm as the sun comes up, and the return of southerly winds will result in warmer temperatures tonight mostly in the 40s. Some patchy fog may be possible again, as warmer and more humid air moves in. High pressure then begins to build back into the southeast, and mild weather will continue through mid week with high temperatures on a slow climb.
