Narrative:
ATIS said 10000 ft broken, 400 ft scattered but I did not see any lower clouds and I was confident that the overcast was high. I departed (VFR) runway 21 and at about 500 ft AGL, entered IMC. I could not detect the lower layer due to the low light at dawn and after climbing through to the clear I could see that the whole river valley was closing in with fog. I am instrument rated and current but a VFR pilot likely would of panicked and lost control. I should have known that it was too dark to judge the ceiling. My instincts told me before takeoff to file IFR but I ignored them. Next time I will heed them.

Title: PLT OF A C210 INADVERTENTLY ENTERED IMC CONDITION RIGHT AFTER TKOF DUE AN UNFORECASTED FOG LAYER FORMING OVER ENTIRE AREA AT 'DAY BREAK.'
Narrative: ATIS SAID 10000 FT BROKEN, 400 FT SCATTERED BUT I DID NOT SEE ANY LOWER CLOUDS AND I WAS CONFIDENT THAT THE OVCST WAS HIGH. I DEPARTED (VFR) RWY 21 AND AT ABOUT 500 FT AGL, ENTERED IMC. I COULD NOT DETECT THE LOWER LAYER DUE TO THE LOW LIGHT AT DAWN AND AFTER CLBING THROUGH TO THE CLR I COULD SEE THAT THE WHOLE RIVER VALLEY WAS CLOSING IN WITH FOG. I AM INST RATED AND CURRENT BUT A VFR PLT LIKELY WOULD OF PANICKED AND LOST CTL. I SHOULD HAVE KNOWN THAT IT WAS TOO DARK TO JUDGE THE CEILING. MY INSTINCTS TOLD ME BEFORE TKOF TO FILE IFR BUT I IGNORED THEM. NEXT TIME I WILL HEED THEM.
