I am super excited to join the University of North Dakota Department of Atmospheric Sciences (
@UNDATSC
) this upcoming fall as an Assistant Professor! I will mainly be teaching the Numerical Weather Prediction course and continuing my research into various aspects of convection!
We are pleased to announce Dr. Jake Mulholland will be joining our faculty as an Assistant Professor this fall! Jake is currently a researcher at the Naval Postgraduate School studying various aspects of convection.

As mentioned in this evening's
@NWSBoulder
forecast discussion, the upcoming 90s/100s F-to-potential accumulating snows across the CO Front Range this weekend into next week is, at least in part, due to downstream influences of WPAC TCs Maysak and Haishen as seen on the 18Z GFS.

Might be a neat example of a squal line--supercell merger event about to unfold across C NE... attached also is a nice schematic from French and Parker's (2014; MWR) paper of this process (also see French and Parker's 2012; WAF observational study of these types of events).
