Area Forecast Discussion National Weather Service Grand Forks ND 1153 PM CDT Thu Jun 13 2019 .UPDATE... Issued at 1146 PM CDT Thu Jun 13 2019 No further changes were made. UPDATE Issued at 958 PM CDT Thu Jun 13 2019 Water vapor loop indicated a weak short over northwest MN and was producing showers over west central MN and couple storms over eastern ND. Upper level ridge axis was over eastern MT. Another short wave was located along the MAN/Ontario border in the northern stream. Low level jet is expected to increase overnight with approaching ridge axis from the west and short wave over eastern MAN. Showers and thunderstorms are expected to develop overnight with low level jet and low level moisture transport. Raise overnight low a tad. UPDATE Issued at 656 PM CDT Thu Jun 13 2019 Tweaked sky conditions and pops for the evening. No other changes at this update. && .SHORT TERM...(This evening through Friday) Issued at 345 PM CDT Thu Jun 13 2019 Northwest flow remains in place with weak/disorganized energy rotating across the region. Southerly flow has led to some increases in Tds, and with WAA/increased temps, lapse rates have increases and there is enough instability to support showers or even a few thunderstorms through this evening with a little better forcing as a mid level shortwave rotates over our CWA overnight leading to a possible increase in shower/thunderstorm coverage. Overall, instability not expect to be enough to support severe threat through tonight. Friday-Friday night: A slightly stronger trough axis rotates into the region after midnight and chances may increases overnight. Behind this there may be a lull in coverage before an even stronger mid level trough passes through the region. As this trough approaches surface low pressure will deepen sliding south and east towards our southern CWA, and an associated frontal zone will set up across the southern part of our CWA. This front will delineate warm sector where ML CAPE may increase to the 2500 J/KG range and better shear 30-40kt to the north. There is some question to whether this shear will overlap or not, but even it fit doesn't there should be potential for severe updrafts in our south with hail/wind still the main concerns. Presence of frontal zone and potential for deep layer shear to be further south raises the potential for more organized convection and all modes of severe being in play (including isolated tor threat). Some CAMs show possible linear complexes developing along this front and tracking through our southern CWA, but consensus is low and other CAMs favor disorganized clusters. .LONG TERM...(Friday night through Thursday) Issued at 345 PM CDT Thu Jun 13 2019 Saturday and Sunday... The unsettled pattern will continue into the weekend with showers and storms possible, especially on Saturday. Surface-based CAPE values of 500-1000 J/kg will prevent any large-scale severe event. Bulk shear values of 30-60 knots suggest the possibility of stronger storms. Current models suggest that the greatest chance for stronger storms will be in southern portions of region. Sky cover will keep temperatures fairly mild during the day with most areas seeing highs in the mid-60's to mid-70's. For Sunday, a more northerly shift in winds and cloud cover will keep instability limited. Also, this wind shift will lead to cooler temperatures across the area with much of North Dakota and northern Minnesota seeing highs in the 60's. Shear and CAPE values will still allow for development of showers and storms, but coverage will be low. Chances of rain will taper off by the night. Monday to Thursday... Monday and Tuesday are looking generally calm with temperatures in the 70s. There will be a trough starting to dig into the Northern Plains from the Canadian Rockies by the middle of the week. This trough will be the area of interest for Wednesday and Thursday. Models are beginning to disagree with the placement and the timing of this trough, GFS is hinting at an occluded low sitting around Central North Dakota while the ECMWF is placing this low further north into Manitoba. The placement of the low will dictate where a moisture tongue will create the most instability. && .AVIATION...(For the 06Z TAFS through 06Z Friday night) Issued at 1146 PM CDT Thu Jun 13 2019 Mid clouds will dominate thru the pd. A surface boundary will slide south into northern ND Saturday with winds turning east then northeast behind it. Timing of this boundary is uncertain. Not expecting a sudden gusty wind shift though. Scattered showers and t-storms to be over the area, with the usual timing issues looking ahead leading to some VCTS vs predominate. && .FGF WATCHES/WARNINGS/ADVISORIES... ND...None. MN...None. && UPDATE...Riddle SHORT TERM...DJR LONG TERM...NC/BSW/JRS AVIATION...Riddle
