First off, what are you using to calculate the strike temp, and what vessel are you mashing in?
Some of these mash calculators online do not allow for thermal loss adjustments. That means what ever vessel you are using as a mash tun has to be pre-heated or else it will absorb some heat lowering the mashes target temp.
try this calculator out to see if you can see how much thermal loss you had.
you need to:
Measure grain temp just prior to dough in
how much grain in pounds and how much water in either qts or gals, and desired temp
by tracing what your last brew was off by you can bump up the thermal loss to adjust the strike temperature needed. http://www.brewheads.com/strike.php
