Exactly, and that is why the winds are expected to be 100-120 knots in that area. The jet stream is the dividing point between cold and warm air. When a low pressure system moves in, it brings cold air from the north due to the counter clockwise rotation of the winds. The greater the contrast of warm and cold air, the stronger the jet stream is. Also in order for a low pressure system to move from its source region, it needs a push from above (jet stream). The jet stream also provides vorticity which allows clouds to from and that is why we get bad weather with low pressure. High pressure is sinking air with inhibits clouds to form, thus we get good weather. Pay attention to the low moving in from the Pacific Northwest. If it moves farther north than expected, we might miss the rain, but still expect at least overcast skies and strong winds aloft (turbulence).
