Area forecast discussion, Jun 30, 12:40 AM CDT, 1 minute before
Area Forecast Discussion...UPDATED National Weather Service Grand Forks ND 1240 AM CDT Sun Jun 30 2019 .UPDATE... Issued at 1240 AM CDT Sun Jun 30 2019 Severe weather threat has ended along and west (ND side) of the Red River Valley. Radar imagery as of 1230 am shows an west-east MCS spreading from the Red Lakes west to Thief River Falls. Expect this complex to continue along the warm sector/instability gradient slanting southeast across northern MN toward Duluth, MN overnight, bringing the main threat for severe weather with potential for damaging wind gusts and large hail. Cannot rule out some isolated thunderstorms developing out ahead (south) of this line as well across MN lakes country. UPDATE Issued at 953 PM CDT Sat Jun 29 2019 Strong capping and lack of strong surface heating (due to morning/afternoon convection) prevented a significant portion of the area from destabilizing this evening. Current focus is on an area of weak surface convergence from Hallock MN to Carrington ND where new cells have eroded capping sufficiently enough to maintain updrafts beyond the freezing level. Updated rain chances to focus on the evolution of this region as it progresses eastward. However, these storms are moving northeast toward northwest MN where SPC mesoanalysis shows strong shear and instability weaken considerably, so may be difficult for semi- discrete storms to maintain strength long enough to reach severe limits. Most likely scenario at this point seems to be one in which storms merging into a MCS with severe wind threat given strong 850mb jet nosing up the RRV. UPDATE Issued at 634 PM CDT Sat Jun 29 2019 Updated aviation discussion for 00z TAF issuance. && .SHORT TERM...(This evening through Sunday) Issued at 350 PM CDT Sat Jun 29 2019 The exiting mesoscale convective complex brought severe weather to parts of ND and even a little into NW MN this morning/early afternoon. The rain cooled air from the thunderstorms put a damper on heating today, thus cancelled the heat advisory for all counties except the far SW. Severe storms still look to be likely this evening with a growing tornado threat in the western zones. The latest Supercell Tornado Parameter (STP) has an area up to 9 over southcentral ND...and the favorable conditions are expected to drift east over the next few hours. The SPC has a 10% tornado area in the far west in their Enhanced Risk. Discrete supercells are expected right away with hail/wind/tornado all a concern across eastern ND, esp the Devils Lake to Valley City area. Models hint the storms may morph into a line and move east...most likely across the northern Red River Valley and into NW MN. Although the best chance the line will affect the north...it is possible the whole area will see this line of storms later tonight. Temps stay warm tonight...with lows in the upper 60s. After that a few showers/storms may affect the far south tomorrow, but most of the activity should be to the south of the area. Highs will be mostly in the 80s on Sunday. .LONG TERM...(Sunday night through Saturday) Issued at 350 PM CDT Sat Jun 29 2019 The overview is that the large scale pattern over the Northern Plains will become more westerly early next week as ridge breaks down and upper low drops out of the Arctic into northern Manitoba through the first part of the week. Eventually southwest flow will redevelop for a time, but there is little change in 500 heights, so temps through the extended will tend to be near (or slightly below) normal in the upper 70s/lower 80s for highs. These pattern shifts will keep an active storm track within the vicinity of our CWA, resulting in several opportunities for shower and thunderstorm chances through the extended period. A period of potentially better severe chances is Tue and Tue night where strong synoptic forcing in the form of an upper jet streak, mid level shortwave trough, and surface cold front are shown to drop near or over our CWA. At least elevated instability would be supported with adequate deep unidirectional shear to suggest the threat of hail and damaging wind. Looking ahead to Independence Day and Friday, increasing southwest flow will raise the possibility for more shower and thunderstorm activity. Details in these later periods are still uncertain though and will be refined with time. && .AVIATION...(For the 06Z TAFS through 06Z Sunday night) Issued at 1240 AM CDT Sun Jun 30 2019 Expect VFR conditions for all TAF sites except KBJI late tonight and early Sunday AM. As a complex of storms progresses southeastward (leaving TVF) toward DLH, expect TSRA to affect KBJI over the next few hours with potential for large hail and damaging winds. TSRA threat for KBJI ends by 12z, but lingering MVFR cigs are possible through much of the morning. Other sites will see a similar trend to KDVL, with anvil overcast cirrus giving way to mostly clear skies and southeast winds turning northwest as a cold front passes through late tonight. && .FGF WATCHES/WARNINGS/ADVISORIES...
