Marine Weather and Tides
Version 3.4 |
12/16/2019 NOAA is having trouble with requests that include wind gusts. I am posting graphs without wind gusts until it gets fixed. 10/9/2019 Updated the Marine Zones. 9/4/2019 Fixed the weather maps due to NOAA moving them. 7/25/2019 New feature in the Airports section gives a link to 5 minute updates for data reports. |

NEAR TERM. (Through Sunday) Issued at 324 PM EDT Sat Apr 4 2020
. Clearing tonight, sunshine returns Sunday .
High Impact Weather Potential: None.
Pattern Synopsis/Forecast: Sharp short-wave ridging/narrow ridge of warm air continues to progress through the central Great Lakes downstream from broader troughing/cold air rotating through the northern Plains/Upper Midwest. Short-wave trough/1.5 pv anomaly is swinging up through Ontario/Manitoba with a weak-ish area of low pressure across northern Ontario and cold front that arcs down into Lake Huron (front just passed through APN a short time ago). Narrow corridor of light precipitation along and behind through front has been gradually passing through the forecast area. Largely of the liquid variety although there was a period of snow in eastern Upper Michigan and light accumulation reported in the Soo area.
Upstream, high pressure and substantially drier air is just across the lake with a sharp clearing line already pushing into Lake Michigan. Some lake cloudiness is across central/eastern Lake Superior. No lake induced precip on radar, although ERY continues to report -SN.
Cold front and attending light precipitation will continue to slide off the Lake Huron coast and east of the region heading into the evening. High pressure and substantially drier air build into the region tonight and dominate through Sunday.
Details: No big changes to the going forecast. Cold front and attending light precip will slide east of the region this evening while cooler and substantially drier air overspreading the region tonight. We should see a fair amount of clearing skies as we go through the night although with todays rainfall and minimal mixing there might be some lingering low level moisture/stratus hanging around through the night into Sunday morning.
High pressure and a fairly dry airmass dominate the region on Sunday with forecast sounding temp/dewpoint profiles substantially "opening up" through the day. Any lingering stratus that may be lingering around Sunday morning will quickly erode/mix out through the morning . with abundant sunshine anticipated thereafter. This will lead to temperatures easily rebounding into the middle 40s to middle 50s for high temps.
SHORT TERM. (Sunday night through Tuesday) Issued at 324 PM EDT Sat Apr 4 2020
. Slightly above normal temperatures .
High Impact Weather . None is expected.
Forecast Concerns . Pops through the period.
Surface high pressure holds across the region through the first half of Sunday night yielding mostly clear skies and when combined with light winds, cold overnight low temperatures. Increasing mid/high clouds late Sunday night. Various short waves moving by to our north and south Monday into Tuesday will bring chances for a few rain showers. High temperatures are expected to generally be a few degrees above average in the upper 40s to the upper 50s. Cold as mentioned above Sunday night with lows ranging from the upper teens in low lying spots to the mid 20s. Lows Monday night in the milder 30s for the most part.
LONG TERM. (Tuesday night through Saturday) Issued at 324 PM EDT Sat Apr 4 2020
. Turning colder .
High Impact Weather . Minimal as of now.
Forecast Concerns . How chilly it will turn late next week and whether or not we'll see any snow.
Zonal flow from early in the week will be replaced with a long wave trough aloft from mid week into next weekend (at a minimum). This trough will be the conduit for sending modified chunks of arctic air into the Great Lakes region. In addition, upper level disturbances moving through the flow will bring chances for precipitation in the form of rain and snow showers. Some spots could even see a little snow accumulation Thursday night into Friday (which would not be totally unusual). After one more mild day Wednesday, temperatures are expected to be several degrees below average for the remainder of the forecast period. Unfortunately to many peoples dismay, the pattern looks like it will remain chilly through the middle of the month.
AVIATION. (For the 00Z TAFS through 00Z Sunday evening) Issued at 742 PM EDT Sat Apr 4 2020
IFR cigs improving to VFR this evening.
A cold front is moving east of Lake Huron. Associated showers have exited ne lower MI. Low cigs (high-end IFR to low-end MVFR) are lingering behind the front, with clearing progressing eastward across northern Lake MI. This clearing will quickly improve cigs from w to e this evening. VFR conditions are expected overnight into Sunday . for the most part. Patchy stratus could redevelop overnight, will not include in the current set of TAFs given uncertainty as to exactly where to include, but something to monitor closely.
Ongoing somewhat breezy nw to n winds will diminish tonight.
MARINE. Issued at 324 PM EDT Sat Apr 4 2020
Behind a departing cold front, gustier north/northwesterly winds will impact the the region tonight leading to a period of marginal small craft advisory conditions on parts of the Great Lakes. Winds/waves weaken substantially on Sunday with no marine impacts expected through the first half of the week.
APX WATCHES/WARNINGS/ADVISORIES. MI . NONE. LH . SMALL CRAFT ADVISORY until 8 AM EDT Sunday for LHZ347-348. LM . SMALL CRAFT ADVISORY until 8 PM EDT this evening for LMZ345-346. LS .
