Areas affected...portions of northern North Dakota
Concerning...Severe potential...Watch unlikely=20
Valid 042308Z - 050015Z
Probability of Watch Issuance...20 percent
SUMMARY...A few instances of severe gusts/hail may accompany the
stronger storms that can develop over the next few hours. The severe
threat is expected to remain relatively isolated.
DISCUSSION...A small, embedded 500 mb vortmax is cresting the ridge
across northwest ND per latest RAP analysis, which is likely
supporting convective initiation along multiple outflow boundaries
strewn across the state. Overall storm coverage along these
boundaries should remain limited given the overall weak upper
support. Surface temperatures exceeding 80 F amid mid to upper 60s F
dewpoints, overspread by 7.5 C/km tropospheric lapse rates, are
contributing to 1000+ J/kg MLCAPE per 22Z mesoanalysis. Stronger
mid-level flow is also contributing to 40+ kts of effective bulk
shear, supporting storm organization for any updraft that can become
sustained. Should a storm mature, transient supercell structures may
result and would be associated with a large hail/severe wind threat.
