(on/off) Help NOTE: mouseover dotted underlined text for definition| Fxus63 kapx 242300 afdapx area forecast discussion national weather service gaylord mi 700 pm edt Fri may 24 2019 Near term (through tonight) issued at 327 pm edt Fri may 24 2019 The marginal risk... high impact weather potential... Thunderstorms tonight run a marginal risk of becoming severe. The most likely thing expected would be general thunderstorms with wind gusts of 35-45 mph, and small hail. However, there is a small threat that a thunderstorm could become severe (>60 mph >1" hail). Pattern synopsis forecast... The warm front looks to have moved into the region but has been stymied from moving much farther north by the convection that has moved along it since this morning. This has also produced cloud cover that has been able to keep daytime heating down, and with the warm front well to the south, the dewpoint remains around 50. The warm front is expected to move a little more north, allowing some of the warm sector to move into lower michigan. The soundings from the models show strong sfc based inversions with some limited elevated convection overnight, through at least 09z sat. After 09z sat, the cold front begins to cross the region pushing the warm air southeast. However, there is a 30-40kt llj around 850 mb that will head into the warm front overnight and push east across the lower peninsula, primarily south of m-55, and possibly us-10. Primary forecast concerns... With all of the ingredients, it looks like the best area for severe convection will be south of us-10 as the LLJ and the warm front move east through the evening and overnight. Based on this, think that our chance for severe convection will be late as the LLJ warm front tries to get the northern end of the line of convection to push north of m-55. Not impossible, but think that trying to get severe north of m-72 and m- 32 will be difficult with the sfc based inversion, and based on the mode of convection that has moved through the region today. If the line gets organized south of us, then we will expect stratiform rain with embedded thunder that would blow north off of the storms. It could become a heavy rain situation, which we also stand at a marginal chance (5-10%) for exceeding flash flood guidance. Short term (Saturday through Monday) issued at 327 pm edt Fri may 24 2019 high impact weather potential: minimal. A few thunderstorms remain possible Saturday. Pattern synopsis forecast: anomalously strong upper level ridge and attendant very warm air remains anchored across the SE states into the gulf, with 594 dm h5 heights observed on a couple gulf states 12z soundings this morning. In the wake of yesterdays system, upper level ridging has managed to build up through the great lakes over the last 24 hours or so. Upstream, larger scale troughiness is bottled up across the western CONUS with short-wave energy and attendant surface low pressure advancing up through the dakotas heading toward canada. In between, strong deep layer S SW flow has spread low-mid level warm moist air up through the midwest and just now pivoting into the western southern great lakes region. Active weather has will continue along this axis heading into the weekend. Through the upcoming holiday weekend, strong upper ridge will remain anchored across the SE gulf coast states through the entire weekend and into early next week. Initial short-wave energy surface low moving through the northern plains today will get shunted up through the far NW great lakes and into ontario through Saturday while attending surface cold front slowly sags down through northern michigan... And upper level heights across the great lakes get knocked back down a few ticks. High pressure settles in for Sunday and into the first half of memorial day. But another wave of low pressure ejects out of the plains and through the lower lakes region along the stalling front, bringing rain chances back to the region for later Monday and Monday night. Primary forecast concerns challenges: minimal. Lingering shower chances Saturday. Short-wave and surface low pressure will be crossing up through the far NW great lakes into ontario Saturday morning with a cold front trailing down through the midwest and surface warm front lifting up through northern michigan. Showers and some thunderstorms will probably be ongoing early Saturday morning across lower michigan as low-mid level moisture axis continues to spread into the region on a |
stout low level jet. Moisture axis and LLJ will eventually fold back into southern lower michigan with the majority of showers storms diminishing as we get into the afternoon. Meanwhile, non-descript surface cold front will eventually sag down through northern michigan late in the afternoon into the evening ushering in cooler air heading into Sunday. But with cooling aloft and lingering low level moisture daytime heating, soundings and model instability forecasts show several hundred j kg MLCAPE Saturday afternoon, and suggests the possibility for a few more showers thunderstorms later in the afternoon into the evening as the front moves through. We are not outlooked for any severe storm threat. But with strong mid level flow and 0-6 km bulk shear values in excess of 40 knots supportive of organized updrafts, for any storms that might develop it's something we will have to keep an eye on. High pressure builds back into the region for Sunday into early Monday. Still think we will have at least a fair amount of sunshine on Sunday although with continuing weather off to our south, there may be some mid and high cloud cover around. Back into the below normal column for temperatures on Sunday with readings in the middle 60s to lower 70s. Monday begins quiet. But another round of showers will be moving into the region later in the day (see below). Long term (Monday night through Friday) issued at 327 pm edt Fri may 24 2019 high impact weather potential: minimal. An overall wet and cool-ish week ahead. Northern michigan will remain on the northern periphery of ridging anchored over the SE gulf coast states through at least midweek with more of less zonal flow across the great lakes and stalled boundary draped across the lower lakes ohio valley region. Aforementioned low pressure ejecting out of the plains along the boundary is still looking to bring a round of rainfall through the region Monday night into Tuesday, with another wave and round of showers later Tuesday into Wednesday. Longer range guidance today continues to advertise a fairly substantial closed low and core of cold air dropping down out of canada into the great lakes for the latter half of the week. Guidance (ecmwf in particularly) is not quite as cold in great lakes vs yesterdays solutions. But regardless... More shower potential while temperatures get knocked back to several degrees below normal to bring a close to meteorological "spring" 2019. Aviation (for the 00z tafs through 00z Saturday evening) issued at 700 pm edt Fri may 24 2019 showers and thunderstorms expected late tonight. MVFR to ifr conditions very late tonight and much of Saturday. Parent low pressure will move from the northern plains to far northern ontario. A weaker low will cross mi early Saturday. Showers and thunderstorms are expected to develop late tonight, mainly after 06z. Occasional MVFR ifr vsby restrictions are possible. As precip is departing, a longer period of cig restrictions are forecast for very late tonight and much of Saturday. Ifr CIGS are progged at apn mbl, and MVFR at tvc pln. Se winds will veer south tonight, and SW Saturday, and will be a touch gusty at times. Some llws is possible tonight. Marine Issued at 327 pm edt Fri may 24 2019 winds will remain variable at 10 knots or less as the pressure gradient remains rather slack around the low pressure tonight. Winds will increase, but looks to remain below small craft overnight. A cold front will move through the upper great lakes Saturday morning, and with the cooler air and tightened gradient, small craft winds will be expected for Saturday afternoon. Then high pressure builds into the region Saturday night and drop off again and remain below small craft criteria through Sunday. Apx watches warnings advisories Mi... None. Lh... None. Lm... None.
