Has there been more than one day above 70 this year?    Maybe, cannot remember.  1990 had 4 days in the 80's before St Pats day. 
 
	 
 
	Edit-just checked.  2 days so far but MDT is only at 66 as of 3 PM.   So I looked at one year, 1990....it had 5 days above 70 before St Pats day (and St Pats day was in the 70's as well).   So,  not such a rare feat.  Only one day in March, March 1, does not feature record high temps in the 70's.   17 out of the 31 March days have records 80 and over.
