LATEST UPDATE . Aviation

SYNOPSIS. Issued at 330 AM EDT Sun May 31 2020

- Cool Sunday and Monday then warming up

- Chance of storms Monday night and Tuesday night to Wednesday

DISCUSSION. (Today through next Saturday) Issued at 330 AM EDT Sun May 31 2020

-- Cool Sunday and Monday then warming up --

We will remain in the comfortably cool and dry air today with the center of high pressure located very near southwest Michigan this afternoon. Somewhat warmer air will begin advecting in on Monday, but the truly warmer and more humid air will arrive on Tuesday. 850 mb temperatures between 12Z Sunday and 12Z Tuesday will climb 12 degrees C, so this will be quite the change in airmass. There is pretty strong model agreement for highs in the lower 80s on Tuesday away from the lake. A growing spread in temperature solutions exists from Wednesday onward, but temperatures will in the 70s if not the 80s should continue for a few days. It will be a rather amplified upper level pattern over North America late in the week with a ridge buckling poleward over the northern high plains, so warm temperatures next weekend are not quite a lock at this point depending on downstream trough amplification. The 00Z ECMWF is an example of this, though it may lie on the cold side of the ensemble range.

-- Chance of storms Monday night and Tuesday night to Wednesday --

A couple rounds of convection appear possible for the first half of the week: first warm-advection-related elevated storms Monday night, then potentially surface-based storms ahead of a cold front late Tuesday. Given NAM and GFS forecast soundings, it is conceivable that deep enough instability will be present with adequate shear, especially late Tuesday, for storms to be capable of hail. Strong winds may also be possible depending on near- surface instability and dry mid-layers. Specifics of storm evolution is still pretty low- confidence at this point.

AVIATION. (For the 18Z TAFS through 18Z Monday afternoon) Issued at 128 PM EDT Sun May 31 2020

VFR conditions will continue through Monday morning. West winds around 10 knots this afternoon will be decreasing to 5 knots overnight.

MARINE. Issued at 330 AM EDT Sun May 31 2020

Winds and waves will likely become hazardous to small craft Monday afternoon through Tuesday morning. There may be enough instability above the marine layer Monday night for thunderstorms which could produce local gale-force winds.

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. 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.
