Narrative:

Student and I departed day for the practice area centered 15 mi north of day. A standard VFR WX briefing obtained at approximately XA30 local time made no mention of flight precautions for IFR and listed the lowest expected WX for the time of our flight as 3000 ft broken and 5-7 mi visibility. The ATIS broadcast at day at the time of departure called a ceiling of 2600 ft and 7 mi visibility. Shortly after lift-off, areas of what appeared to be light rain became visible to the north. We were assigned a heading of 300 degrees and climbed to our requested altitude of 2500 ft MSL as we entered the first of the very light, drizzly precipitation. We then requested and were given a right turn to the north and were told to proceed to the practice area. Shortly thereafter, we began to pass through the bases of a scattered layer at 2500 ft MSL and the visibility dropped to 3 mi. At this time we decided to return to the airport and made a right turn to 090 degrees toward what appeared to be clrer WX. We informed ATC of our situation and requested a return to the airport. Before ATC could respond, the clouds again thickened and I brought us around to a 180 degree heading. ATC said we couldn't stay sbound for very long and wanted us to fly a 060 degree heading. That was unacceptable due to the clouds, and I told her we could either fly 180 degrees or descend to 2000 ft MSL. ATC gave us a 180 degree heading at 2500 ft over the top of day for a landing on runway 24L. Prior to landing, I passed a PIREP to the tower controller. The student learned several things on this outing. The WX in ohio during this time of yr can change very rapidly. Flight service can be wrong. If an ATC clearance cannot be complied with, fly the plane first, notify ATC of the situation, and request an amended clearance. If unforecast/unrpted WX is encountered, pass on a PIREP to ATC or FSS to aid fellow pilots. If you're flying along and run into adverse WX, make a 180 degree turn and fly out of it.

Title: INSTRUCTOR PLT AND STUDENT PLT ENCOUNTER UNRPTED, UNFORECAST, IMC.

Narrative: STUDENT AND I DEPARTED DAY FOR THE PRACTICE AREA CTRED 15 MI N OF DAY. A STANDARD VFR WX BRIEFING OBTAINED AT APPROX XA30 LCL TIME MADE NO MENTION OF FLT PRECAUTIONS FOR IFR AND LISTED THE LOWEST EXPECTED WX FOR THE TIME OF OUR FLT AS 3000 FT BROKEN AND 5-7 MI VISIBILITY. THE ATIS BROADCAST AT DAY AT THE TIME OF DEP CALLED A CEILING OF 2600 FT AND 7 MI VISIBILITY. SHORTLY AFTER LIFT-OFF, AREAS OF WHAT APPEARED TO BE LIGHT RAIN BECAME VISIBLE TO THE N. WE WERE ASSIGNED A HDG OF 300 DEGS AND CLBED TO OUR REQUESTED ALT OF 2500 FT MSL AS WE ENTERED THE FIRST OF THE VERY LIGHT, DRIZZLY PRECIPITATION. WE THEN REQUESTED AND WERE GIVEN A R TURN TO THE N AND WERE TOLD TO PROCEED TO THE PRACTICE AREA. SHORTLY THEREAFTER, WE BEGAN TO PASS THROUGH THE BASES OF A SCATTERED LAYER AT 2500 FT MSL AND THE VISIBILITY DROPPED TO 3 MI. AT THIS TIME WE DECIDED TO RETURN TO THE ARPT AND MADE A R TURN TO 090 DEGS TOWARD WHAT APPEARED TO BE CLRER WX. WE INFORMED ATC OF OUR SIT AND REQUESTED A RETURN TO THE ARPT. BEFORE ATC COULD RESPOND, THE CLOUDS AGAIN THICKENED AND I BROUGHT US AROUND TO A 180 DEG HDG. ATC SAID WE COULDN'T STAY SBOUND FOR VERY LONG AND WANTED US TO FLY A 060 DEG HDG. THAT WAS UNACCEPTABLE DUE TO THE CLOUDS, AND I TOLD HER WE COULD EITHER FLY 180 DEGS OR DSND TO 2000 FT MSL. ATC GAVE US A 180 DEG HDG AT 2500 FT OVER THE TOP OF DAY FOR A LNDG ON RWY 24L. PRIOR TO LNDG, I PASSED A PIREP TO THE TWR CTLR. THE STUDENT LEARNED SEVERAL THINGS ON THIS OUTING. THE WX IN OHIO DURING THIS TIME OF YR CAN CHANGE VERY RAPIDLY. FLT SVC CAN BE WRONG. IF AN ATC CLRNC CANNOT BE COMPLIED WITH, FLY THE PLANE FIRST, NOTIFY ATC OF THE SIT, AND REQUEST AN AMENDED CLRNC. IF UNFORECAST/UNRPTED WX IS ENCOUNTERED, PASS ON A PIREP TO ATC OR FSS TO AID FELLOW PLTS. IF YOU'RE FLYING ALONG AND RUN INTO ADVERSE WX, MAKE A 180 DEG TURN AND FLY OUT OF IT.
