Area Forecast Discussion National Weather Service North Platte NE 336 AM CDT Thu Jul 2 2020

SYNOPSIS. Issued at 336 AM CDT Thu Jul 2 2020

H5 analysis from earlier this evening had a closed low over southern New England with a trough of low pressure extending south into the western Atlantic. Further west, high pressure was located over Lake Michigan. A ridge extended northwest of this feature into northern Manitoba. West of this feature, a closed low was located over western Alberta with a trough extending south into the Pacific NW states. Across the central CONUS, weak southwesterly flow was noted and extended from the Four Corners into the Dakotas and western Nebraska. At the surface, a trough of low pressure extended from southeastern Montana, south into eastern Colorado. Low pressure was noted across southeastern Colorado with a frontal boundary extending east into southern Kansas and the Arkansas Ozarks. Overnight, skies were mostly clear across western and north central Nebraska. Temperatures as of 2 AM CDT, ranged from 59 at Broken Bow to 69 at Gordon.

SHORT TERM. (Today through Friday night) Issued at 336 AM CDT Thu Jul 2 2020

Low level moisture will continue to advect into the forecast area this morning thanks to easterly and southeasterly winds. Will continue to monitor cloud development across northern Kansas and far southern Nebraska for inclusion in this morning's forecast. Based on the latest NAM12 soln, the best potential for low level cloud development will be across the far southwestern forecast area. ATTM, this should remain just off to the southwest of North Platte. Hot and humid conditions will develop by afternoon with readings in the lower 90s. By late afternoon the threat for thunderstorms will increase in the far western forecast area as storms develop INVOF a surface boundary draped across the western panhandle, eastern Wyoming and NE Colorado. Forecast SB capes in the NAM this afternoon reach 5000J/KG along and west of a line from North Platte to Rushville. With little to no cap noted late this afternoon, thunderstorm development is a good possibility along the surface boundary. Deep layer shear is on the order of 25 to 30 KTS this afternoon/evening, so the severe threat appears meager at best. However, very steep mid level lapse rates (H5-H7) are noted in the western third of the forecast area- favoring a large hail threat. By evening, activity will transition east into central and eastern Nebraska overnight into Friday morning, with the severe threat ending by mid evening. On Friday, precipitation chances will linger in the east in the morning with dry conditions expected for the afternoon in most locations. There will be an increased threat for thunderstorms late Friday afternoon in the west. Deep layer shear is very weak tomorrow afternoon, so there is some doubt as to how far convection can reach central and eastern Nebraska Friday night.

LONG TERM. (Saturday through Wednesday) Issued at 336 AM CDT Thu Jul 2 2020

The synoptic pattern will remain largely unchanged through the middle of next week. High pressure and ridging aloft will remain the dominant weather feature across the central and southern plains. This will focus the brunt of thunderstorm activity off to the west and north of the forecast area. There will be some minor chances for thunderstorms during the late afternoon and evening hours as weak forcing lifts along the western and northern periphery of the ridge axis. ATTM, the NBM has low pops primarily during the late afternoon and evening hours and this seems plausible given the flow pattern. Temperatures will remain above normal through midweek and may trend warmer late next week into next weekend.

AVIATION. (For the 06Z TAFS through 06Z Thursday night) Issued at 1246 AM CDT Thu Jul 2 2020

VFR to prevail for most locations across west central Nebraska through the forecast period. That being said, the latest solutions advertise MVFR stratus moving across SW Nebraka after 08z. If this occurs we would expect a rapid burn off with the high sun angle. Most of the low stratus should remain south and southwest of KLBF, but there's enough support for at least a prevailing MVFR mention in the forecast for KLBF. Otherwise isolated thunderstorms are a possibility for locations generally along and west of Highway 83 this afternoon, confidence in thunderstorm placement is low due to the isolated nature. If storms form, extreme instability in the atmosphere would present a large hail threat with erratic wind.

LBF WATCHES/WARNINGS/ADVISORIES. None.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
