The Line of Wind Discontinuity is an established pattern during pre monsoon period. Actually the depression caught hold of this line or it moved close to this line.
This time the Line of Wind Discontinuity is well pronounced at higher levels too.
At higher latitudes this discontinuity line is weak and thus the system will dissipate soon over central India and there wont be much moisture dragging from seas and thus DRY TS / DUST storm or sometimes TS with light rain will be possible.
