Trend and Expectancy Guidelines
The trend of the last 3 half-hourly estimates is nearly constant
The speed of the coldest tops is nearly constant, but not quasi-stationary
No mergers or intersections with boundaries are expected
The time of day is still favorable
The system continues in the same topographic region
The direction of the warm, moist, low-level inflow maintains its orientation with the direction of movement of the coldest tops
Hourly surface data show no change in dewpoint, precipitable water, or stability of low-level inflow
