Narrative:
I turned a student loose on a cross country from arb to alma and back. A front was southwest of fwa and sbn. I felt that the forecast for frontal passage at XD00 was pessimistic. With a XA00 am departure I thought the student would be back at XC30 am. I included a deviation to lansing in his signoff in case WX worsened. I did not check 18000 ft winds to see how fast the front was actually moving. I was in the run-up area when I heard the tower call the aircraft repeatedly. I inquired as to the problem. Apparently the student was lost and disoriented. After being turned over to detroit approach he descended out of radio contact. I took vectors to the student's position in hopes of visual contact to lead him home. I was vectored within 1 mi of his position and never saw him. Visibility was 1/2 to 3/4 of a mi. Between approach and I we talked the student home. 1) I will stress the importance of landing when facing deteriorating conditions. The student passed 3 airports while being forced lower. 2) I will look at 18000 ft winds when trying to gauge a front's speed. 3) spend more time on WX theory with solo cross country students.

Title: STUDENT IN C152 BECAME DISORIENTED WHEN ENRTE WX DETERIORATES. ATC AND HIS INSTRUCTOR IN ANOTHER ACFT LEAD HIM HOME. THE STUDENT PREFLT BRIEFING BY HIS INSTRUCTOR WAS INCOMPLETE.
Narrative: I TURNED A STUDENT LOOSE ON A XCOUNTRY FROM ARB TO ALMA AND BACK. A FRONT WAS SW OF FWA AND SBN. I FELT THAT THE FORECAST FOR FRONTAL PASSAGE AT XD00 WAS PESSIMISTIC. WITH A XA00 AM DEP I THOUGHT THE STUDENT WOULD BE BACK AT XC30 AM. I INCLUDED A DEV TO LANSING IN HIS SIGNOFF IN CASE WX WORSENED. I DID NOT CHK 18000 FT WINDS TO SEE HOW FAST THE FRONT WAS ACTUALLY MOVING. I WAS IN THE RUN-UP AREA WHEN I HEARD THE TWR CALL THE ACFT REPEATEDLY. I INQUIRED AS TO THE PROB. APPARENTLY THE STUDENT WAS LOST AND DISORIENTED. AFTER BEING TURNED OVER TO DETROIT APCH HE DSNDED OUT OF RADIO CONTACT. I TOOK VECTORS TO THE STUDENT'S POS IN HOPES OF VISUAL CONTACT TO LEAD HIM HOME. I WAS VECTORED WITHIN 1 MI OF HIS POS AND NEVER SAW HIM. VISIBILITY WAS 1/2 TO 3/4 OF A MI. BTWN APCH AND I WE TALKED THE STUDENT HOME. 1) I WILL STRESS THE IMPORTANCE OF LNDG WHEN FACING DETERIORATING CONDITIONS. THE STUDENT PASSED 3 ARPTS WHILE BEING FORCED LOWER. 2) I WILL LOOK AT 18000 FT WINDS WHEN TRYING TO GAUGE A FRONT'S SPD. 3) SPEND MORE TIME ON WX THEORY WITH SOLO XCOUNTRY STUDENTS.
