I would like to congratulate brendan(sorrygottarunway) on his first big PIC decision. Yesterday on the way back from Redding, PA, after getting several briefings, and checking the METAR's, we took off. The METAR's and forecasts agreed that the ceilings would be an overcast layer at around 4600' east of the hudson river, with 10 miles or greater visability. As we were about 15 or so miles out of Farmingdale, we discovered that there was a broken layer at 3000', and we were at that same altitude. We managed to just barely skim that layer, as we advised approach that we were descending to 2500'. Getting an update of the winds at farmingdale, they were 050@17, with runway 1 in use. So we happened to get copious amounts of windshear. The decision came when we thought about our trip from farmingdale to danbury. The ceilings were more like 3500-4000', not anything above 4500'. With that broken layer that we discovered, we called FSS, and made a PIREP. Brendan then made the decision to not go until we were positive about the cloud layer, as he does not have his instrumet ticket yet, but is taking his checkride this week. Our route back would also take us over the long island sound, where an IFR Advisory was issued for likely IMC conditions. Brendan and I then called our CFII's to get their opinions on the issue. After that, he made the decision to wait a little while, and not think about the common "getting home-itis". Just wanted to publically congratulate him on that!
