You’re headed to Minneapolis today to pick up your daughter from college and bring her home to Milwaukee for a family wedding. Since winter is starting to recede, it looks like a good chance to dust off your 1978 Cessna 172 and make the 2 1/2 hour flight from KMWC to KFCM. You’ll spend the night in Minneapolis, then fly home tomorrow morning. You’re working on your instrument rating, but you don’t have it yet, so this will be a strictly VFR flight. You are current in the airplane and have over 200 hours in it since buying it 4 years ago.
Read the weather briefing below, then decide if you’re making the trip or not. Your proposed departure time is 2130Z.
Your route will take you northwest from the Milwaukee area, across central Wisconsin and into Minnesota.
The current surface analysis shows a weak low pressure system off to the southwest.
The 12-hour prog chart doesn’t show much action with that front.
The 24-hour forecast chart is a little more worrying, although the valid time is for tomorrow afternoon.
The radar is pretty clear across your entire route of flight, with the only significant precipitation well south of your route.
The satellite image tells the real story here, with some areas of fairly thick cloud cover. This is worth investigating more.
It looks like clouds are your main worry today, so you start with a look at Weather.aero’s new ceiling and visibility tool.
That overview picture looks pretty benign, which is encouraging. But there are a few green METAR circles in western Wisconsin, so it’s smart to dive into the METARs and TAFs for all the details. Here are the current weather reports for your departure, five en route airports and your destination:

Your departure and destination look pretty good, and even the winds look light. But a few of those en route stations are reporting lower ceilings. Now let’s look at the forecasts for your departure area and destination:

Are you going or calling the airline? The weather at your departure and destination are both pretty good, winds are light and there’s plenty of daylight left. But are the 2300 ft. ceilings in western Wisconsin enough to scrap the flight? Even with good visibility? And what about the return trip?
