357 AM MDT MON SEP 12 2016 Today and upr level trof wl lie from MT southwestward into nrn CA. As a result, the MAV guidance temps are a little cooler than the MET guidance, although the difference is not really significant. There could be some isold showers ovr some of the high country before noon today, but most pcpn chances wl hold off until afternoon. Moderate southwest flow aloft progged across the region into the middle of the week, as a broad upper trough digging across the Pac Northwest Monday night, carves out an upper low across the Great Basin on Tuesday.
03Z surface analysis showing high pressure parked across Lake Erie and this will be the dominant feature for the short term period. Otherwise cool start to the day with temperatures in the low to mid 50s for most. This high pressure will move east into the Mid Atlantic Coast through the day with more moisture return and warmer temps will be the story this afternoon. Given the mostly clear conditions again tonight would suspect another reasonable ridge valley temperature split will be in place by Tuesday morning. Upper ridging will remain parked across the southeastern U.

205 AM MDT MON SEP 12 2016 Splitting upper trough will bring increasing clouds all areas, with increasing chances for precip over the western third today. High center lift from the splitting northern stream trough will support a band of rain showers into the western third of the fa, initially in a waning fashion as it shifts east. Cooling profiles will support a mix of snow on some portions of the ne WY plains, with a trans to all snow expected in the higher elevations of the northern Black Hills, esp above 5. Trough and associated lift will exit the region Tues, with a few lingering rain showers possible across the far nw.

The lowered temps for the wedge development still look appropriate, and neighbors seem to be in better agreement with our thinking.
455 AM CDT MON SEP 12 2016 An upper trough will approach the Panhandles from the western states this week with a cold front slowly tracking south into the Oklahoma Panhandle by sunset this evening and then into the northern Texas Panhandle by late tonight. The cold front may push as far south as the central Texas Panhandle by daybreak Tuesday and then across the far southern and eastern portions of the forecast area by late Tuesday morning. Increasing isentropic lift behind the cold front on Tuesday. and the approaching upper trough from the west will allow for chances for convection to continue by Tuesday afternoon through late this week.
/issued 236 PM CDT SUN SEP 11 2016/ A weak upper level high will move off to the east and mid level winds will be backing from a more southwesterly direction this week as a trough slowly develops over the western US.

Cold front has advanced through north- central Montana and will continue moving south this evening. Web cams at Two Medicine Bridge. Additional slushy snowfall is expected along I15 through Elk Park, but have decided against a winter weather advisory for this area with less than half an inch snowfall forecast and road surface temperatures forecast to remain well above freezing. In southwest Montana, skies remain cloudy with isolated showers possible through Tuesday as the upper level trough closes off over the Great Basin.
The upper level trough sliding down the back of the upper level ridge well offshore will continue to slide southwards just east of the forecast area today. As the upper trough continues south and closes over the bay area.
425 AM EDT MON SEP 12 2016 A broad upper ridge will continue across the southeast during the period.
The rain showers near and behind the advancing cold front will linger over our southern and southeastern zones mainly this morning before moving beyond our CWA by this afternoon and evening. With the cold front now through the region, the colder air will filter through the area and settle across northeast Montana over the next day or two. The upper level trough axis will continue to slowly make its way across the northern Rockies and the northern high plains regions. As skies are expected to clear out tonight, and winds are expected to become light and variable if not calm, the stage is set for low temperatures tonight through early Tuesday morning to drop down to the freezing mark or just below the freezing mark, probably between midnight tonight and 8 AM Tuesday morning.

a low pressure system moving southward into California and Nevada will bring stronger onshore flow with cooling to 5 to locally 10 degrees below average.
A strong cold front pushed through the region today and in its wake gusty northerly winds are funneling into the region. The high resolution models indicate a wind switch from northwest to northeast across north Idaho this evening, possibly enhanced by the convection. For Monday, it will be dry and slightly cooler.
358 AM CDT MON SEP 12 2016 Cold front as of 08z just to the west of the forecast area across central South Dakota. As the cold front moves through, cooler air will take hold. Chances will be kept on the low side.
A weak disturbance had passed through the region and cooler overnight temps are expected. For tomorrow our region will be sandwiched between high pressure to the west and low pressure to our south.
122 AM EDT MON SEP 12 2016 High pressure builds in through Monday and moves into the northern Atlantic Tuesday and Tuesday night as a cold front approaches.
310 AM CDT MON SEP 12 2016 Dry high pressure centered over NY/PA extended into Mid TN early this morning with clear skies and temperatures in the 50s. Through daybreak, readings will dip into the low to mid 50s with patches of fog developing mainly over lakes and rivers. Humidity will remain tolerable with strong vertical mixing lowering dew points into the low to mid 50s in the afternoon. Upper level ridging will gradually strengthen. This will bring even warmer temperatures and a return to uncomfortable humidity levels. The upper level ridge will keep conditions mostly rain free, but there will be enough instability for the possibility of isolated thunderstorms.
An upper ridge over Montana will be flattened by an upper trough moving through the Canadian Prairies this morning. Then, a cold front will drop south across the forecast area late this afternoon and early evening. Air mass will become somewhat unstable ahead of the cold front allowing for the chance of thunderstorms. Upper trough over Western Canada along with a secondary cold front drops south into Montana during the day which will bring enough moisture with it for a chance of showers and thunderstorms. With the trough over Montana Thursday night, the southwest half of the forecast area will have deep moisture over it with showers possibly thunderstorms.
The low level pattern is very weak with weak wind flow. Brief upper level ridging, a weak cap, and lack of a trigger will give us a quiet weather day with hot and humid conditions. Dewpoints will begin in the lower 70s Thu morning, but mix out into the upper 60s later in the afternoon. Max heat indices will end up in the lower 90s. The low level jet will be pointed into east central MN Fri evening and then veer east across central WI overnight.

A weak upper level trough will move across the Great Lakes this afternoon, potentially yielding a few showers and storms in our area. A stronger cold front is expected to move across the region over the weekend bringing a good chance of rain. Highs through the remainder of the work week will generally be in the low to mid 80s with lows in the mid to upper 60s. A few lingering showers in our south this evening as elongated/positively tilted trough and associated convergent boundary slowly push out of our area.
213 AM EDT WED AUG 17 2016 A weak cold front will wash out over the area tonight. As high pressure settles into the Ohio Valley region by Thursday, drier conditions are expected for the end of the workweek. Another cold front will approach the Ohio Valley this weekend. Low temperatures tonight will range from the upper 60s in the northwest to the lower 70s in the southeast. Drier conditions are expected to filter in Wednesday night as high pressure begins to settle into the region. Expecting an atypical temperature pattern on Wednesday as clouds and precipitation will keep the south cooler than the north. Highs will top out in the lower/mid 80s in the north and upper 70s/near 80 in the south. However, surface ridging will remain in place, keeping a generally warm and moist pattern from completely exiting the region.
Latest guidance and trends indicate low temperatures will be a bit warmer than previously forecast for much of the area. A region of high pressure over North Dakota will keep the short term period quiet through Wednesday. But an approaching cold front will begin an active thunderstorms pattern starting Wednesday night. By Wednesday the high pressure area departs to the east as low pressure in Montana brings return moisture and warmth to the region. An approaching cold front in Saskatchewan will be the focus for scattered thunderstorms by Late Wednesday afternoon Severe weather is not expected Wednesday evening as the better 0-6km shear and cape remain to the north of the region. Wednesday night and Thursday will be more active for thunderstorms as a cold front moves through from northwest to southeast across the state.
225 AM EDT WED AUG 17 2016 Cold front will move through the forecast area today providing more rain and thunderstorms. Another cold front this weekend. Cold front and upper level short wave support will continue to move slowly through the region on Wednesday night and exit on Thursday. Somewhat cooler and drier air This will keep the area dry.
Byrd Dry weather to persist through Thursday night for the most part, then as ridge moves to our east, southerly flow to return once again. Will see increasing moisture and instability ahead of a strong cold front.
414 AM EDT WED AUG 17 2016 A weak area of high pressure will build in with drier conditions today. A an upper level trough may bring a brief showers to the north and mountains tonight and Thursday.
424 AM EDT WED AUG 17 2016 Fair weather is expected into this afternon as weak high pressure builds in from the west. A weak upper level trough will move across the Great Lakes this afternoon, potentially yielding a few showers and storms in our area. A stronger cold front is expected to move across the region over the weekend bringing a good chance of rain. Highs through the remainder of the work week will generally be in the low to mid 80s with lows in the mid to upper 60s. An upper level trof should move into the area this afternoon and should help trigger scattered thunderstorms. An upper level short wave trof will amplify and move across North America this weekend.
A cold front will approach northern North Dakota this evening. At this time most models are indicating the highest threat will be across the southern James Valley.
A weak ridge of high pressure will build into the Ohio valley later today and tonight. A better chance of storms will occur over the weekend as a cold front moves through. Dry and cooler weather will occur after the weekend as high pressure builds our way. High Res models indicate showers may continue across our far south and southeast this morning and diminish this afternoon as the a weak cold front moves to the east and gradually dissipate. Went with highs in the lower 80s today and lows in the upper 60s tonight which is near a MOS blend.
High pressure will bring hotter temperatures and fewer thunderstorms early this week. As high pressure shifts off to the east, deeper moisture will return along with an increasing chance of thunderstorms the second half of the week. I'm less inclined to emphasize that scenario this time due to a brief and modest strengthening of the remaining portion of the ridge that's still over our area this afternoon.
Synoptic setup has not changed much in the past day or so, with a weak upper level ridge nosing into the southeast states from the western Atlantic. Along the periphery of this ridge, from east Texas up to the Ohio Valley, there is a band of cloudiness and enhanced moisture. Over the weekend, the upper ridge is forecast to weaken further and allow a dip in the jet stream to push into the Tennessee Valley.
