Area Forecast Discussion National Weather Service Grand Rapids MI 718 PM EDT Sat May 26 2018 LATEST UPDATE... Aviation .SYNOPSIS... Issued at 319 PM EDT Sat May 26 2018 Temperatures will warm to near record readings for the remainder of the Holiday weekend, with highs across the area reaching mostly into the low 90s. It will be noticeably cooler immediately near Lake Michigan, however, where some morning and early afternoon fog will be possible. Chances for showers and thunderstorms Sunday will remain east of a line from Big Rapids to Battle Creek, keeping the Grand Rapids area and the lakeshore dry. Dry weather is expected for Memorial Day. && .SHORT TERM...(This evening through Monday night) Issued at 319 PM EDT Sat May 26 2018 Warm and unstable airmass will continue to favor showers and thunderstorms this afternoon and evening where a trigger exists for upward forcing. Best chance will be over the far southeast portion of the forecast area (Jackson/Ingham counties), closer to upper energy tracking through the Ohio Valley. Another area where we will have better potential for development will be along/north of M-10 as a weak surface trough tracks through Northern Michigan. Very slow storm motion and high PW values (1.1 to 1.4 inches per AM Raobs and model estimates) will bring potential for heavy downpours with storms that develop. Modest ML CAPE (1000-1500 J/kg) but low shear may allow strong but brief updrafts to develop. Biggest threat from storms will be gusty winds, and of course lightning. Showers and thunderstorm potential will decrease through the evening as shortwave trough passes through and drier air at the mid-levels works in. Another warm and muggy night is in store for the area as dewpoints remain in the 60s. Min temps tonight should also reach low/mid 60s. Warm, high dewpoint airmass, flowing over Lake Michigan will again create potential for fog (some dense) to develop along the lakeshore tonight into Sunday afternoon, similar to today. We will slowly transition to surface high pressure and ridging aloft Sunday and Monday. Stability provided by warming mid-levels should keep the far western portion of the state dry tomorrow. Showers and thunderstorms will remain possible roughly east of a line from Big Rapids to Battle Creek during the afternoon and evening. Dry weather is then expected Sunday night through Monday night as ridging at the surface and aloft settles in overhead. Potential for fog over and near Lake Michigan will continue each night through early afternoon. Continuation of seasonably hot conditions will likely be the most noticeable weather trend of the Holiday weekend as temperatures the next few days soar to near records (see below). Warming trend can be expected the next few days as H850 temps rise to near 18C and 588dm ridge builds at H500 near Chicago. Grand Rapids May 26...90 (2010) May 27...93 (1911) May 28...92 (1978) May 29...92 (1962) Lansing May 26...90 (1911) May 27...93 (1911) May 28...96 (1874) May 29...94 (1895) Muskegon May 26...87 (2010) May 27...86 (2012) May 28...89 (2012) May 29...93 (1962) .LONG TERM...(Tuesday through Saturday) Issued at 325 PM EDT Sat May 26 2018 Main forecast concern in the long term are the chances for heavier rain mid week associated with moisture from the former tropical system Alberto. Quite a bit of uncertainty with a developing tropical system that at this point is still off the west coast of Cuba. That said, the ECWMF and GFS are in pretty good agreement in bringing a slug of moisture associated with the former system through our area Wednesday and Thursday. PWAT values will be off the chart for this time of year, in excess of 2.00 inches. Thinking we are looking at a steady moderate to heavy rain (with some embedded thunder) from Wednesday into Thursday. QPF totals at this point are not all that high around 0.75 to 1.00 inch. Some of the ensemble members nudge up into the 1 to 2 inch range and that seems reasonable given tropical moisture. Bottom line, there is still some uncertainty with the direction the moisture goes, but a focus will be on this system for sure going forward. Otherwise, the long term looks fairly uneventful with mainly dry weather Tuesday and Tuesday night. There could be a spotty shower or storm Tuesday afternoon, but coverage should not be large. Cannot rule out a few showers and storms Thursday night into Friday as well, before 500mb ridging takes hold again into Friday night and Saturday. A warm period overall, with highs topping out around 90 on Tuesday, cooling into the mid to upper 70s as the rain moves through mid week. && .AVIATION...(For the 00Z TAFS through 00Z Sunday evening) Issued at 718 PM EDT Sat May 26 2018 A few storms this evening in lower Michigan but these should avoid Terminal Forecast locations. Otherwise...some reduction in visibility due to fog may be possible for 3 to 6 hours early Saturday at all forecast locations but confidence is low in this occurring. && .MARINE... Issued at 319 PM EDT Sat May 26 2018 Main concern for marine interests will continue to be potential for dense fog to form as a warm and moist airmass remains in place through Tuesday. The highest potential will be from late each night through early afternoon. Otherwise, the weather is expected to remain quiet as thunderstorm potential remains mainly east of the lake and winds stay fairly light. && .HYDROLOGY... Issued at 319 PM EDT Sat May 26 2018 River stages continue falling. This trend will continue through the holiday weekend. The next risk for basin wide, measurable rainfall will hold off until the middle of next week when the remnants of Alberto will likely move into the Great Lakes region. Projected rainfall amounts may boost a few river sites out of their banks, but flooding appears unlikely at this time given the progressive nature of the system across the area. Trends will continue to be monitored. && .GRR WATCHES/WARNINGS/ADVISORIES... MI...None.
