If a storm form in the southwest and be forced to the left of a normal track (Charts 10 and 11), another storm will immediately begin to develop in the southwest and it becomes a sure rain producer. Storms that develop in the southwest and move normally are quickly followed by clearing weather. 3. Troughs of low pressure moving from the west are of two types--the narrow and the wide. The former moves eastward slowly and storm centers develop in the extreme northern and the extreme southern ends. When the trough is wide, the development of an extensive storm area is not uncommon, especially if the wide intervening area between the Highs shows relatively high temperatures. 4. When the northern end of a trough moves eastward faster than the southern end, the weather conditions in the south and southwest remain unsettled and the chances are that a storm will form southwest of the High that follows. When the southern end moves faster than the northern end, settled weather follows. 5. Storms that start in the northwest and move southeastward do not gather great intensity until they begin to recurve to the northward. At the time of recurving they move slowly, as a rule, and care must be exercised in predicting clearing weather. 6. Marked changes in temperature in the southeast and northwest quadrants imply an increase in the storm's intensity. Small temperature changes do not indicate a further development of the storm. 7. Abnormally high temperatures northwest of a storm indicate that it will either retrograde or remain stationary. 8. East of the Rocky Mountains, a storm which moves to the left of its normal track increases in intensity. 9. Storms with isobars closely crowded...
