Area Forecast Discussion National Weather Service Goodland KS 646 AM MDT Thu Jun 1 2017 .UPDATE... Issued at 645 AM MDT Thu Jun 1 2017 Just completed an update to add fog and to increase the cloud cover this morning. && .SHORT TERM...(Today through Saturday night) Issued at 337 AM MDT Thu Jun 1 2017 Main forecast issue will be continued chances for thunderstorms. Satellite showing a progressive and somewhat amplified flow over the most of the Pacific. From along the west coast of North America into the far western Atlantic a highly amplified flow exists with also some split flow in the western portion of this amplified flow. At jet level...models initialized fine. At mid levels...models started out close but would give a slight advantage to the Canadian, Gfs, and Ecmwf. Models appear to start a little warm today. At this time it looks like the Ecmwf, Canadian, and Sref were doing the best. Today/tonight...Very moist low level air mass in place right now. However the winds are steady with a decent amount of mid and high level cloud cover around. So at this time do not think there will be fog but will continue to watch. Surface wind and pressure field chaotic right now due to major thunderstorm complex/MCV that plowed through our area during the night. Significant cold pool forced the front further south. The high resolution and Cams caught last nights convection and the resulting wind field. As it looks now the front looks to only move back through the southern half of my area by 18z and does not move north of the area until mid afternoon. Analysis and satellite showing a lot of low level moisture and moisture in the ridge aloft as it moves into the area today. There looks to be a decent amount of instability around. However, the surface focus will be north and west of the area during peak heating with no lift aloft around due to the ridge on top of us. However, with all the residual moisture and continued south to southeast winds around, could see an isolated thunderstorm develop over almost anywhere in the forecast area. Not enough confidence to insert any chance through the evening hours so left it dry. After midnight the next shortwave to affect our area will be approaching the western portion with adequate moisture and instability still available. It will be a low probability but did insert a slight chance of thunderstorms after midnight. Friday/Friday night...Models in good general agreement in bringing a shortwave trough through the area in weak west to northwest flow aloft during the afternoon and into the night. The shortwave also pushes a cold front through during the night. Models show little to no inhibition with a generous amount of Cape. Even though the flow will be weak there will be veering with height. Also instability indices would support a chance that some of these storms could become severe. Of more important note, models have precipitable water values in the 1 to 1.5 inch range with the mean flow only 5 to 15 knots. So no matter how much severe there will be, these storms look capable of producing moderate to heavy rainfall. Forecast builder gave me medium to high chance pops and that looks reasonable for now. However, it is possible that these will need to be raised. High temperatures also look fine. However, cloud cover could affect how warm it gets. Saturday/Saturday night...Tricky forecast. Above mentioned shortwave only moves ever so slowly through the area with the ridging behind it staying just to the west of our through late afternoon. Models do not have shortwave south and east of our area until during the evening hours. The forecast builder echoes this with a slight chance to low chance of precipitation until early evening. Hard to argue against that so for now will keep that chance. Temperatures will be cooler in a post front upslope air mass. Did lower the temperatures given to me a touch because of this and residual cloud cover and precipitation. .LONG TERM...(Sunday through Wednesday) Issued at 237 AM MDT Thu Jun 1 2017 An active pattern will prevail across the central High Plains through the extended period. Ridge axis remains centered over the CWA on Sunday before moving slightly to the east overnight into Monday. There will be highly amplified troughs on either side of the ridge both east and west in a block type pattern. Sunday will remain dry; however, moisture advection will continue into the region with persistent southeasterly flow in the lower levels. The ridge will slide slightly further eastward late Monday and into Tuesday with PoPs returning to the forecast area late Monday afternoon. Continued moisture advection will increase PW values to near 1.5 inches in portions of the CWA. This combined with weak flow aloft and slow storm motion will increase the risk of flash flooding with any thunderstorm development on Tuesday. A slow moving, embedded shortwave will provide a focus for thunderstorm development on Tuesday that will persist through the night and into Wednesday. As we head into Wednesday afternoon, slgt chc PoPs remain in the forecast as the weak shortwave pushes through the region. The ridge will rebuild and amplify on Thursday with diminishing PoPs across much of the area during the morning with a chc of thunderstorms during the afternoon along a dryline that will begin to set up in along the CO/KS border. Model agreement through the extended period is mixed, with decent agreement through around 06Z Monday and little to no agreement thereafter. && .AVIATION...(For the 12Z TAFS through 12Z Friday morning) Issued at 541 AM MDT Thu Jun 1 2017 Vfr conditions are expected through the period. For Kgld...very light fog, 6sm, will be possible for the first few hours of the period. Light and variable winds will gradually to south in the afternoon and increase into the 10 to 15 knot range. These winds will continue through the end of the period. For Kmck...light and variable winds will shift to the southeast in the afternoon as the speeds to near 10 knots. The winds shift to the south around 06z at near the same speed. Low level wind shear will develop around 06z and continue through the end of the period. && .GLD WATCHES/WARNINGS/ADVISORIES...

The South Beaver Creek overflowed its engineered channel and followed the natural channel of the creek bed. This caused the creek to wash out a small section of CR 74 east of the CR 74/CR 24 intersection near the bridge over the South Beaver Creek.
