(on/off) Help NOTE: mouseover dotted underlined text for definition| Fxus63 kapx 262011 afdapx area forecast discussion national weather service gaylord mi 411 pm edt Sun may 26 2019 Near term (through tonight) issued at 411 pm edt Sun may 26 2019 Quiet bonfire weather tonight... high impact weather potential: none. Pattern synopsis forecast: great lakes remains nestled within westerly flow aloft along the northern periphery of a strong upper ridge centered along the gulf coast. Per water vapor satellite imagery, weak short-wave trough is passing through the western great lakes with little fanfare across northern michigan. All the weather action remains confined well south through southern lower michigan and into the ohio valley, along the cold front that passed through our area last night. Across northern michigan, weak surface high pressure and dry air is in control. We had quite a bit of thick high cloud cover from the weather to our south earlier in the day. That has largely thinned and slipped off to the south east leaving some afternoon heating of the day fair weather clouds across interior parts of the forecast area. There is a narrow w-e band of lower cloud cover just north of lake superior that will eventually slip into the region toward Monday morning. Tonight: heating of the day CU will fade quickly this evening leaving mainly clear skies for much of the night. Aforementioned narrow band of lower cloud cover will begin to slip down into the region late overnight and result in a bit more clouds for some by morning. But otherwise, a quiet night ahead with winds going calm this evening and temperatures dropping down into the 40s. Short term (Monday through Wednesday) issued at 411 pm edt Sun may 26 2019 high impact weather potential... Heavy rain possible (low probability for now) Monday. Pattern synopsis forecast... As a system moves from the c rockies, and into the c plains, the warm front stretches along a well defined sfc trough into S lower. The GFS and ECMWF have this system similarly portrayed at 12z mon, but begin to diverge a bit as we go into the day, and into the evening the GFS begins to push the qpf, from a mcs, more north than the ECMWF (see the primary forecast concerns for more). The system continues to move east into the mid- atlantic states, allowing high pressure to build into the state and give us a pause in the rain for about 12 hours. Around 00z wed (Tuesday evening) the warm front remains, and the main low moves more out into the c plains. This looks to kick off another MCS that both models seem to have similar solution with through the day on Wednesday. Primary forecast concerns... The main concern over this will be the convection that is fired off along the warm front over the 2 1 2 days of the period. The first instance, as mentioned above, is the difference in the where the QPF goes. The GFS and ECMWF have two slightly different solutions, as the ECMWF has a MCS that follows the warm front, which stays somewhat stationary in S lower, and dumps the rain mainly just south of m-55, and possibly up to m-72. The GFS deepens a small sfc low in the trough, and pushes the warm |
front north. This causes isentropic rain elevated thunder with possibly heavy rain, north around m-32, while more convection fires south of there in S lower mi. This seems problematic as the high ahead on the north side of the warm front helps to produce east to northeast winds at the sfc. Which would impede the warm air from moving north much like the GFS idea. The sref namnest namdng hiresw(arw nmm) all support the ecmwf, so have used a blend for that. The GEFS plumes show about 3 members with decent CAPE to support the operational gfs. So think that the thunder will mainly remain south of the forecast area. So the main issue will be not thunder, but the possibility of heavy rain. While, it is possible, not really expected, as it seems that it should fall with the mcss that track along the warm front. Long term (Wednesday night through Sunday) issued at 411 pm edt Sun may 26 2019 high impact weather potential... Thunderstorms Wednesday night extended (Wednesday night through Sunday)... There's a brief pause with the rain as the second MCS moves through, and then warm front resets as the low moves closer and another MCS with the low moves into the region and rain comes back into the region overnight and Thursday. The models disagree with the evolution of the system that drops into the middle of the country. The GFS continues to cut off the 500 mb low which continues the chances for rain through Friday, while the ECMWF idea is a more open wave that lifts out and high pressure dries things out for Friday. Saturday, both models have rain, but from different systems. However, by Sunday both models have the trough(east coast) ridge(central conus) configuration that dries us out for the early part of the following week. Aviation (for the 18z tafs through 18z Monday afternoon) issued at 144 pm edt Sun may 26 2019 high pressure across the region will provide solidVFR weather for northern michigan through the TAF period. That said, expect sct- bkn fair weather CU through the afternoon with bases at or above 4k feet along with sct-bkn high cloud cover. Clouds thin out tonight leaving mainly clear skies. Cloud cover will begin to increase again late overnight and particularly Monday morning (stillVFR) as our next system begins to move into the region. Overall light winds under 10 knots this afternoon and nearly calm tonight. Easterly winds develop Monday and increase to around sustained 10 knots will a little higher gusts. Marine Issued at 411 pm edt Sun may 26 2019 light winds and waves anticipated through tonight. Easterly winds develop on Monday and remain in place for the next few days.

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. |
